Description


[0001] This application claims priority to China Patent Application No. 201710614917.4, filed on July 27, 2017 to China Patent Office and entitled "Visual Field Testing method and System Based on Head-Mounted Testing Equipment, and Testing Apparatus", which is hereby incorporated by reference in its entirety.

Field



[0002] The present invention relates to the technical field of medical testing, and more particularly relates to a visual field testing method and system based on head-mounted testing equipment, and testing apparatus.

Detailed Description of the Embodiments



[0035] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below in combination with the drawings in the embodiments of the present invention. Obviously, the embodiments described herein are part of the embodiments of the present invention, not all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skilled in the art without creative efforts shall fall within the protection scope of the present invention.

Embodiment I



[0036] As shown in Fig. 1, the embodiment of the present invention provides a visual field testing system based on head-mounted testing equipment. The visual field testing system of the present embodiment may include: electronic equipment 01, the head-mounted testing equipment 02 and an eye movement tracking system 03.

[0037] The eye movement tracking system 03 may be located in any electronic equipment independent from the above electronic equipment 01, as shown in Fig. 1(a), or may be located in the electronic equipment 01, as shown in Fig. 1(b). The present embodiment does not limit the position, and may be adjusted according to an actual need.

[0038] It should be noted that when the eye movement tracking system 03 is independent from the electronic equipment 01, it communicates with testing apparatus in the electronic equipment 01 and is located on the head-mounted testing equipment 02 to acquire a movement state of a pupil of a to-be-tested eye of a subject in real time, for example, acquiring a plurality of images of the pupil of the to-be-tested eye of the subject through an infrared imaging photographing method. Or, the eye movement tracking system 03 is connected with shooting apparatus of the head-mounted testing equipment 02 to control the shooting apparatus to acquire the movement state of the pupil of the to-be-tested eye of the subject in real time. The present embodiment may be adjusted according to an actual need.

[0039] The electronic equipment 01 of the present embodiment may be integrated with the testing apparatus, i.e., an application program for testing the to-be-tested eye of the subject. In addition, the eye movement tracking system 03 may also be integrated in the electronic equipment 01, and is also an application program for acquiring a movement track of the pupil of the to-be-tested eye. At this time, the testing apparatus in the electronic equipment 01 interacts with the eye movement tracking system 03 to realize a test on the to-be-tested eye of the subject.

[0040] During use, the electronic equipment 01 may be located in the head-mounted testing equipment 02, and image information in a screen of the electronic equipment is displayed within a visual field range of the head-mounted testing equipment.

[0041] The electronic equipment 01 of the present embodiment may be a mobile phone, an IPAD or other sets of equipment with display screens. The head-mounted testing equipment 02 may be virtual reality (VR) glasses, or a VR visual field analyzer or a VR tester, and the present embodiment is not limited thereto.

[0042] In the embodiment of the present invention, the visual field testing range of the subject depends on the size of the visual field of the head-mounted testing equipment, such as the VR glasses. For example, the visual field testing range may reach about 40 degrees in an up direction, a down direction, a left direction and a right direction, and is finally up to actual equipment.

[0043] For example, when the electronic equipment is the mobile phone, the mobile phone may be inserted into the head-mounted testing equipment 02. The head-mounted testing equipment 02 in the present embodiment may be the VR glasses/the VR visual field analyzer.

[0044] In addition, the current head-mounted testing equipment is associated with a controller, such as a common hand shank. When the electronic equipment 01 is located in the head-mounted testing equipment 02 for testing, the electronic equipment is in communication connection with the controller associated with the head-mounted testing equipment, so as to receive a signal transmitted when the subject triggers the controller.

[0045] Generally, the hand shank may be connected to the testing apparatus in the electronic equipment 01 through Bluetooth, so as to realize communication.

[0046] In a specific testing process, a use method of the above visual field testing system may include that:
First step: an input interface of the testing apparatus may receive relevant parameters input by a user after the testing apparatus of the electronic equipment 01 receives a start instruction triggered by the user, and a predicted image of the to-be-tested eye is displayed on a testing interface after the parameter setting is completed.

[0047] The start instruction of this step may be understood as an instruction that the user triggers the testing apparatus to be turned on through a screen of the mobile phone. For example, the user double clicks an icon, corresponding to the testing apparatus, in a touch display screen of the electronic equipment, and then the testing apparatus is turned on.

[0048] After the testing apparatus is turned on, the mobile phone may be used to take a picture to acquire a head portrait of the subject/an image of the to-be-tested eye, and the subject may manually type in user information (name, sex, age, file label, remarks, identity card information and the like) or set other testing related parameters in the input interface of the testing apparatus and enter the testing interface.

[0049] Other testing related parameters may include: the number of the tested eye, the color (red, yellow), etc. of a stimulation light source, duration of stimulation points, the interval time of the stimulation points and the like.

[0050] In addition, in the present embodiment, the above-mentioned predicted image of the to-be-tested eye may be an image of a center point/center dot displayed in a white background. The image information partially reflects the other testing related parameters. The center point/center dot may be a pre-displayed reference element for assisting in acquiring the movement track of the pupil in the electronic equipment.

[0051] Second step, the electronic equipment is inserted into the head-mounted testing equipment, so that the image information, i.e., the image information of the testing interface, in the screen of the electronic equipment is displayed in the visual field of the head-mounted testing equipment.

[0052] For example, after the mobile phone is inserted into the VR glasses, the position of the mobile phone is adjusted, and a patient wears the VR glasses with the inserted mobile phone.

[0053] Third step, when the head-mounted testing equipment is arranged in front of the eye of the subject, a focal length button of the head-mounted testing equipment is adjusted such that the image information seen by the pupil of the to-be-tested eye of the subject is clearest.

[0054] Fourth step, a testing process is started after the controller transmits the test start instruction upon receiving the trigger of the subject. That is, the position of the pupil of the to-be-tested eye of the subject is tracked and calibrated, and an eye photo is taken.

[0055] That is, the subject may adjust the focal length of the VR glasses through an adjustment knob (such as a focal length adjustment knob) on the VR glasses, so as to adjust the center dot in the image information to the highest definition, and then the subject operates the controller, i.e., the hand shank, to proceed to the next step. At this time, the testing apparatus may inform the eye movement tracking system in the background to start to monitor the state of the eye.

[0056] The eye movement tracking system is operated in the background, and may select an infrared imaging manner to acquire images, in order to monitor a movement track of a pupil of a single eye of the subject wearing the VR glasses and a blinking state in real time.

[0057] It should be noted that the visual field testing system of the present embodiment may selectively test the single eye only or test two eyes simultaneously. When the two eyes are tested, one is tested at first, and then the testing apparatus will automatically start to test the other eye. A doctor and the patient/subject do not need to carry out any operations, and the test operations are all automatically completed.

[0058] Specifically, the testing apparatus acquires an identity label of the subject before being inserted into the head-mounted testing equipment, such as the VR glasses, and receives the test start instruction after acquiring the identity label.

[0059] For example, the testing apparatus may acquire a picture of the current to-be-tested eye of the subject, and regard an iris of the to-be-tested eye in the picture as a unique label of the to-be-tested eye, so as to be used in generation of a testing report.

[0060] Or, for example, the testing apparatus receives an identity label input by the subject. Generally, in a visual field testing technology, the iris may be used as an identification label.

[0061] It can be understood that a human eye structure is composed of a sclera, an iris, a pupillary crystalline lens, retina and other portions. The iris is a circular-ring portion located between the black pupil and the white sclera, and contains many staggered spots, filaments, corona, stripes, recesses and other detailed features. These features decide the uniqueness of the iris feature, and also decide the uniqueness of the identity identification. Therefore, the iris feature of the eye may be used for the identity identification of the to-be-tested eye of each subject.

[0062] A testing process of the VR glasses with the mobile phone is described below in combination with Fig. 2 and Fig. 3.

[0063] Specifically, referring to Fig. 2, a visual field testing method based on head-mounted testing equipment of the present embodiment may include that:
201, testing apparatus located in electronic equipment transmits a start notification for starting to monitor a movement track of a pupil in a current to-be-tested eye to an eye movement tracking system after receiving a test start instruction transmitted by a controller. For example, the eye movement tracking system may receive a left eye or right eye test start communication signal transmitted by the testing apparatus.

[0064] It should be understood that the controller of the present embodiment is a component that is associated with the head-mounted testing equipment and in communication connection with the testing apparatus of the electronic equipment.

[0065] It should be noted that the testing apparatus may acquire an identity label of a subject after receiving the test start instruction. For example, the testing apparatus pre-acquires iris information of the current to-be-tested eye of the subject as the identity label of the subject, and then receives the test start instruction after acquiring the identity label. That is, a picture of the current to-be-tested eye of the subject may be pre-taken, and the iris information is identified from the picture.

[0066] In addition, before the testing apparatus receives the test start instruction, the testing apparatus may acquire the identity label of the subject, and transmit an instruction for acquiring the iris information to the eye movement tracking system. The eye movement tracking system takes the picture of the to-be-tested eye according to the instruction and transmits the picture to the testing apparatus, so that the testing apparatus identifies the iris information according to the picture to generate the identity label of the to-be-tested eye to guarantee the uniqueness of the to-be-tested eye, and effectively stores a testing report according to the identity label.

[0067] 202, the testing apparatus receives movement state information, transmitted by the eye movement tracking system, of the pupil.

[0068] For example, the testing apparatus may receive distance information between the center of the pupil and a center point transmitted by the eye movement tracking system. The center point may appear in a visual field of the head-mounted testing equipment, and belongs to a pre-displayed reference element for assisting in acquiring the movement track of the pupil in the electronic equipment.

[0069] Or, the testing apparatus may receive information indicating that the pupil is switched from a first state to a second state or from a second state to a first state, transmitted by the eye movement tracking system. The first state here may be understood as a to-be-tested eye open state, and the second state may be understood as a to-be-tested eye closed state.

[0070] Or, the testing apparatus receives a plurality of images transmitted by the eye movement tracking system within a preset time period. Each image includes position information/distance information of the center of the pupil and the center point, and then the testing apparatus determines the movement state information of the pupil according to the distance information in all the images.

[0071] In actual application, if the testing apparatus receives the information indicating that the pupil is switched from the first state to the second state or from the second state to the first state, transmitted by the eye movement tracking system, the testing apparatus needs to transmit prompt information for prompting a state change of the subject.

[0072] 203, the testing apparatus determines the movement track of the pupil according to the movement state information.

[0073] Optionally, the method further includes the following step 204:
204, the testing apparatus generates the testing report by the determined movement track of the pupil.

[0074] The testing report in the present embodiment may include: a start point of the test, an end point of the test, a pause time point during the test, the number of the tested eye, the movement track of the pupil in the tested eye, other information of the pupil in the tested eye, and the like. The present embodiment does not limit the content of the testing report, and makes adjustment according to an actual need.

[0075] It should be noted that the testing apparatus may regard the iris in the to-be-tested eye as a unique identity identification label, that is, the testing report includes the iris information. For example, the testing apparatus may identify the iris information included in the picture transmitted by the eye movement tracking system, and then regard the iris information as the label of the to-be-tested eye.

[0076] Compared with a testing method in the prior art, the method of the present embodiment is simple in testing process, and can improve the comfort of the subject during the test, improve the testing accuracy of the subject and enhance the use experience of the user.

[0077] Referring to Fig. 3, a visual field testing method based on head-mounted testing equipment of the present embodiment may include that:
301, testing apparatus transmits a start notification for starting to monitor a movement track of a pupil in a current to-be-tested eye to an eye movement tracking system after receiving a test start instruction transmitted by a controller.

[0078] For example, if the testing apparatus receives the test start instruction transmitted by the controller, but the pupil of the to-be-tested eye of a subject is not aligned with the above center dot, and at this time, the testing apparatus may transmit third prompt information for prompting the subject to adjust the center of the pupil of the to-be-tested eye to be aligned with the imaging center point, such as voice prompt information.

[0079] After the eye movement tracking system receives a left eye or right eye test start instruction, such as a test start communication signal, the testing apparatus may further prompt a wearer to adjust the sight to be aligned with the center point of imaged content in a content way of voices or VR imaging characters. After the eye movement tracking system monitors the alignment, the visual field test is started by counting down a preset time period, such as 3 seconds.

[0080] The VR imaging characters here may be displayed on a screen of electronic equipment, and seen within the VR visual field.

[0081] It should be noted that the center point may appear in the visual field of the head-mounted testing equipment, and belongs to a pre-displayed reference element for assisting in acquiring the movement track of the pupil in the electronic equipment.

[0082] 302, the eye movement tracking system acquires pupil information of the to-be-tested eye of the subject in real time after receiving the start notification.

[0083] The eye movement tracking system of the present embodiment may acquire pupil image information in real time through an infrared imaging method and analyze the image information to acquire movement state information of the pupil, such as, to monitor a movement track of the pupil of a single eye of the wearer and a blinking state in real time.

[0084] 303, the testing apparatus may receive first prompt information transmitted by the eye movement tracking system when the center of the pupil of the to-be-tested eye of the subject is deviated from the center dot, wherein the first prompt information is information transmitted when the eye movement tracking system determines that a distance between the center of the pupil in at least one image and the center point is greater than a preset threshold within a first preset time period, and used for prompting adjusting the center of the pupil of the to-be-tested eye.

[0085] For example, in an operating state of the eye movement tracking system, the center point of the imaged content in the VR virtual test is used as a main corresponding monitoring region. When the movement track of the pupil of the wearer leaves the center point (+/-0.5 mm), the first prompt information is transmitted. When the movement track of the pupil of the wearer returns to the center point, following second prompt information is transmitted.

[0086] 304, the testing apparatus further transmits, according to the first prompt information, a first alarm signal for prompting the subject to adjust the center of the pupil of the to-be-tested eye.

[0087] For example, the testing apparatus may switch the color of the center fixation point of the to-be-tested eye into a warning color, such as red, that is, the first alarm signal is transmitted.

[0088] For example, the eye movement tracking system determines a position state of an eyeball of the pupil, i.e., the center of the pupil, in real time after starting the monitoring. When the eyeball is not located near to the center point, the testing apparatus may display the center dot on the screen of the electronic equipment in red, and at this time, the wearing position of the VR glasses needs to be adjusted, or the subject needs to adjust the state of the pupil of the to-be-tested eye till the center dot turns into green, that is, the eyeball is located near to the center point, i.e., a first region.

[0089] 305, the testing apparatus may receive the second prompt information transmitted by the eye movement tracking system when the center of the pupil of the to-be-tested eye of the subject returns to the above center dot from the deviated state, wherein the second prompt information is information transmitted for prompting that normal monitoring is executable, when the eye movement tracking system determines that a distance between the center of the pupil in at least one image and the center point is less than or equal to the preset threshold within a second preset time period.

[0090] 306, the testing apparatus may transmit, according to the second prompt information, a second alarm signal for prompting the subject.

[0091] For example, the testing apparatus switches the color of the center fixation point of the to-be-tested eye from the warning color into a normal testing color.

[0092] 307, a preset image video is displayed on the screen of the electronic equipment when the testing apparatus determines that the pupil of the to-be-tested eye is in a normal monitoring state.

[0093] The image video of the present embodiment may be that at least one stimulation point appears in a second region near to the center point. For example, the image information included in the image video may be that stimulation points appear randomly around the center point in a flickering manner.

[0094] For example, the testing apparatus may determine that the pupil of the to-be-tested eye is in the normal monitoring state after receiving the second prompt information; or, the testing apparatus receives at least one image transmitted by the eye movement tracking system, and determines whether the to-be-tested eye is in the normal monitoring state according to a movement state (i.e., the distance between the center of the pupil and the center point) of the pupil in the at least one image.

[0095] 308, the testing apparatus receives stimulation point notification information transmitted by the controller, wherein the stimulation point notification information is obtained by triggering the controller when the pupil of the to-be-tested eye finds that at least one stimulation point appears in the visual field of the head-mounted testing equipment, and
the stimulation point is an element included in each image video frame in the image video.

[0096] It can be understood that in the visual field testing process, there is a normally on dot, i.e., the center dot, in the center of the visual field of the VR glasses. To test a fixed view point, the subject keeps the to-be-tested eye looking at this dot. The stimulation points appear randomly around this dot in the flickering manner. When the subject keeps the to-be-tested eye looking at the center fixed view point, the subject presses the controller in the hand immediately in case of seeing the emerging stimulation points.

[0097] In specific application, after the stimulation point appears at each time, if the subject presses the controller once and only within fixed time, the testing apparatus considers that the patient can see this stimulation point. If the subject does not press the controller within the fixed time, the testing apparatus considers that the subject cannot see this stimulation point. If the subject presses the controller for multiple times, the testing apparatus considers that the subject presses the controller by mistake, and the stimulation point is re-tested in the subsequent test.

[0098] 309, the testing apparatus transmits an end signal after the image video is played completely, and transmits test stop information to the eye movement tracking system.

[0099] After all the stimulation points are tested, the test is ended, and the testing apparatus prompts the subject to take off the equipment. In case of any special situations in the test, the equipment may be taken off in the middle of the test, and then the test is ended manually. At the end of the test, the testing apparatus may inform the eye movement tracking system to stop testing the state of the eye.

[0100] 310, the testing apparatus generates a testing report by the determined movement track of the pupil, reactions of the to-be-tested eye to the stimulation points, and the like.

[0101] The testing report in the present embodiment may include: a testing result of each tested point (displayed in a manner of a polar coordinate system: visible points are green, and invisible points are red);
the total number of the tested points (not include repeatedly tested points), the number of the visible points and the number of the invisible points; a testing duration; the number of times of pausing the test in the testing process; the number of the repeatedly tested points in the testing process; the total number of times of pressing the controller by the subject in the testing process, and the like.

[0102] It can be understood that the testing apparatus may regard the iris in the to-be-tested eye as a unique identity identification label, that is, the testing report includes the iris information. For example, the testing apparatus may identify the iris information included in the picture transmitted by the eye movement tracking system, and then regard the iris information as the label of the to-be-tested eye.

[0103] Or, the testing apparatus pre-acquires a picture of the to-be-tested eye of the subject before starting the test of the subject, and acquires the iris information from the picture for unique identity identification, and the testing report generated at each time includes an identity identification label of the iris.

[0104] 311, the testing apparatus may show a user, such as a doctor or the subject, the testing report.

[0105] That is, the testing result may be selected to be saved and uploaded, or may not be saved, and another test is carried out.

[0106] After the above step 308, the displaying of the image video is paused when the testing apparatus determines that the pupil of the to-be-tested eye is in an abnormal monitoring state;
or, the testing apparatus receives at least one image transmitted by the eye movement tracking system, and pauses the displaying of the image video when the testing apparatus determines that the to-be-tested eye is in an abnormal monitoring state according to the movement state of the pupil in the at least one image;
or, the displaying of the image video is paused when the testing apparatus determines that the pupil of the to-be-tested eye is in an abnormal monitoring state after receiving the first prompt information transmitted by the eye movement tracking system.

[0107] In one optional implementation scene, before the above-mentioned image video is played, i.e., before the stimulation point appears at each time, the testing apparatus may determine whether the pupil of the to-be-tested eye is in the normal monitoring state according to the movement state of the pupil of the eye movement tracking system. If the pupil is in the normal monitoring state, i.e., at least three states of the eye are all normal, the image video is played, at this time, the stimulation point appears in the VR visual field, and the center point is kept in green.

[0108] If the testing apparatus determines that the pupil is in the abnormal monitoring state according to the movement state of the pupil of the eye movement tracking system, the playing of the image video is paused, i.e., the stimulation point is paused to appear, and at this time, the first alarm signal may be sent, namely the center point turns into red. The above process of determining whether the state of the pupil of the to-be-tested eye is in the normal monitoring state according to the movement state of the pupil of the eye movement tracking system is repeated till the subject adjusts the state of the pupil of the to-be-tested eye.

[0109] In addition, after the step 302, in the operating state of the eye movement tracking system, the closed and open states of the eye of the wearer may be monitored in real time. When the to-be-tested eye of the subject is monitored to be closed, eye closed prompt information or the second state prompt information is transmitted to the testing apparatus. When the subject is monitored to open the eye after closing the eye, after-eye-closing eye open prompt information or the first state prompt information is transmitted to the testing apparatus.

[0110] The visual field testing method of the present embodiment is simple in testing manner and convenient to operate, and the subject does not need to fix the head in the testing process, so that the comfort of the subject is improved.

[0111] Further, the background brightness in the testing process of the present embodiment, the color of a center fixation point, and the like can be adjusted and configured according to a condition of the subject, and it is not limited to a dark environment, so that the test is convenient, quick and comfortable.

or, the receiving unit 51 is configured to receive a plurality of images transmitted by the eye movement tracking system within a preset time period, wherein each image includes position information/distance information of the center of the pupil and the center point.

[0119] In a specific implementation process, the receiving unit 51 is further configured to receive first prompt information transmitted by the eye movement tracking system, wherein the first prompt information is information transmitted when the eye movement tracking system determines that a distance between the center of the pupil in at least one image and the center point is greater than a preset threshold within a first preset time period, and used for prompting adjusting the center of the pupil of the to-be-tested eye.

[0120] The transmitting unit 52 is further configured to transmit, according to the first prompt information, a first alarm signal for prompting a subject to adjust the center of the pupil of the to-be-tested eye. For example, the color of a center fixation point of the to-be-tested eye is switched into a warning color.

[0121] In another optional implementation mode, the receiving unit 51 is further configured to receive second prompt information transmitted by the eye movement tracking system, wherein the second prompt information is information transmitted for prompting that normal monitoring is executable, when the eye movement tracking system determines that a distance between the center of the pupil in at least one image and the center point is less than or equal to the preset threshold within a second preset time period;

For example, the color of the center fixation point of the to-be-tested eye is switched from the warning color into a normal testing color.

[0123] In a further optional implementation scene, the transmitting unit 52 is configured to transmit third prompt information for prompting the subject to adjust the center of the pupil of the to-be-tested eye to be aligned with an imaging center point after the receiving unit 51 receives the test start instruction transmitted by the controller.
