The body part in the embodiment may include the head, the arms, the trunk, the lower limbs and the like, which is not limited in the embodiment.

[0083] Step 203: the image recognition device takes a picture to be matched.

[0084] After the relationship is established, multiple game users may start the game, and in the game process, each game user may hold the image recognition device with a hand to photograph a target game user to obtain a picture to be matched, and the photographed game user, i.e. the shot game user, may subsequently be determined according to the picture to be matched and the relationship.

[0085] In addition, in order to simulate shooting actions in the first-person shooter game and improve reality, the image recognition device may play shooting sounds during photographing every time.

[0086] In the first-person shooter game, when ammunitions of the simulative guns used by the game users are exhausted, the game users are required to supplement ammunitions to continue shooting, and may not unlimitedly shoot. Then, in order to simulate a scene where ammunitions are exhausted in the embodiment, a photographing right, i.e. a right of shooting the other game users, may be allocated to each image recognition device in the game process, and the photographing right is controlled according to the number of pictures which have been taken.

[0087] In a photographing process, the image recognition device may record the current number of the pictures which have been taken and update the recorded number of the pictures which have been taken according to detected photographing operation. Then, every time when the image recognition device takes a picture to be matched, the current number of the pictures which have been taken may be acquired at first, the number of the pictures which have been taken is judged whether to be larger than a preset number or not, and when the number of the pictures which have been taken is determined to be larger than the preset number, it is indicated that the pictures taken by the image recognition device have exceeded a limit, the shooting right of the image recognition device is disabled, a picture which is currently taken is ignored, and the photographing right of the image recognition device is enabled again after a preset time length. That is, the timing is recorded when the photographing right of the image recognition device is disabled, and the photographing right of the image recognition device is enabled again when the recorded time length reaches the preset time length.

[0088] In a subsequent process, the current number of the pictures which have been taken is reset to be 0 after the photographing right of the image recognition device is enabled, the current reset number of pictures which have been taken is recorded, and then the game user may continue photographing the other game users with the image recognition device.

[0089] Herein, the preset number may be determined by the image recognition device according to a preset game rule, or may be determined by negotiation of the multiple game users. The preset time length may be determined by the image recognition device according to the preset game rule, or may be determined according to a time length consumed by ammunition supplementation in the first-person shooter game, and there are no limits made in the embodiment.

[0090] In addition, in order to improve flexibility, the image recognition device may provide a resetting option when the photographing right is in an on state. The resetting option is configured to disable the photographing right and set the number of the pictures which have been taken to be 0. Thus, the game user may initiatively click the resetting option at the right time. The photographing right of the image recognition device may be disabled no matter how many pictures have been taken at present when the image recognition device detects clicking operation over the resetting option, and after the preset time length, the photographing right is enabled, and the current number of the pictures which have been taken by the image recognition device is set to be 0.

[0091] For example, the preset number is 12, the preset time length is 3 seconds. When the number of the pictures which have been taken is 11 or the game user is in a safer state and is not required to shoot the other game users, the game user may initiatively click the resetting option and the photographing right of the image recognition device is disabled. After 3 seconds, the photographing right is enabled again, and meanwhile, the number of the pictures which have been taken is reset to be 0.

[0092] Step 204: the image recognition device acquires first body characteristic information corresponding to the picture to be matched.

[0093] The image recognition device may acquire the body characteristic information corresponding to the picture to be matched as first body characteristic information after taking the picture to be matched, thereby determining the photographed game user according to the first body characteristic information and the established relationship. Herein, a process of acquiring the body characteristic information corresponding to the picture to be matched is similar to a process of acquiring the body characteristic information of each game user according to the at least one picture of each game user in Step 202, and will not be repeated here.

[0094] In addition, in order to improve photographing accuracy, the photographed game user may also be determined only according to body characteristic information in a preset central area of the picture to be matched. That is, the image recognition device may determine the preset central area of the picture to be matched and perform characteristic extraction on the preset central area to obtain the first body characteristic information, and does not perform characteristic extraction on other areas except the preset central area in the picture to be matched.

[0095] Herein, the preset central area may be a circular area determined by taking the center of the picture to be matched as the circle center and taking a preset distance as a radius, and may also be a square area determined according to the center of the picture to be matched and the preset distance, which is not limited in the embodiment.

[0096] Correspondingly, the game user is required to aim at the target game user with the image recognition device when photographing the target game user during a practical application, and photographs the target game user only when the target game user is located in the preset central area of a picture displayed by the image recognition device to ensure that an image of the target game user falls in the preset central area. In order to facilitate photographing by the game user, the image recognition device may display a prompting identifier in the preset central area to prompt the game user to align the prompting identifier with the target game user to ensure that the target game user is at a position where the prompting identifier is located when displaying the taken picture. Herein, the prompting identifier may be a red point identifier, a crossed identifier or four arrows pointing to the center of the picture to be matched in upward, downward, leftward and rightward directions, which is not limited in the embodiment.

[0097] Step 205: the image recognition device determines a first user identifier corresponding to the first body characteristic information according to the pre-established relationship between the user identifier and the body characteristic information.

[0098] The image recognition device judges whether the body characteristic information in the relationship is matched with the first body characteristic information or not after acquiring the first body characteristic information, and determines the user identifier corresponding to the body characteristic information matched with the first body characteristic information as the first user identifier according to the relationship when any piece of body characteristic information in the relationship is matched with the first body characteristic information, and the game user indicated by the first user identifier is the photographed game user, i.e. the shot game user. At this time, the image recognition device may display a shooting success prompting message to prompt a photographing success, and may also display the first user identifier to prompt the game user with the shot game user.

[0099] In addition, when every piece of body characteristic information in the relationship is determined not to be matched with the first body characteristic information, the game user corresponding to the image recognition device is determined not to photograph any game user, and then the picture to be matched and the first body characteristic information may be deleted to reduce an occupied storage space. At this time, the image recognition device may also display a shooting failure prompting message to prompt the corresponding game user with a shooting failure.

[0100] Step 206: the image recognition device executes shooting processing operation on the first user identifier.

[0101] Herein, shooting processing operation represents that any shot game user shall be subjected to "punishment" operation, and may be determined according to the preset game rule. The image recognition device may execute shooting processing operation on the first user identifier when determining the first user identifier.

[0102] For example, shooting processing operation may include operation of disabling a game right of the first user identifier, that is, the game right of the first user identifier may be disabled to set the first user identifier into a state of quitting the game after the image recognition device determines the first user identifier, and at this time, the game user indicated by the first user identifier is disabled to perform photographing operation.

[0103] Alternatively, shooting processing operation may include operation of reducing a life value, that is, the image recognition device may maintain a life value of each user identifier, reduces the life value of the first user identifier when the first user identifier which is shot is determined, and disables the game right of the first user identifier when determining that the life value of the first user identifier is lower than a preset threshold value in a subsequent process. Moreover, the image recognition device may reduce the life value of the first user identifier according to a preset difference.

[0104] Herein, the life value may be a numerical value within a preset range. The preset range may be determined according to the game rule. The preset threshold value may be a minimum value within the preset range. The preset threshold value may, for example, be 1 or another integer. The preset difference may also be determined according to the game rule. There are no limits made in the embodiment.

[0105] In addition, when the pre-established relationship includes a relationship among the user identifier, the body part and the body characteristic information. The image recognition device may execute shooting processing operation corresponding to the body part on the first user identifier according to the body part corresponding to the first body characteristic information of the picture to be matched.

[0106] That is, the image recognition device may determine shooting processing operation corresponding to each body part in advance, and shooting processing operation corresponding to different body parts may be the same, and may also be different. When determining that any piece of body characteristic information in the relationship is matched with the first body characteristic information, the image recognition device determines the user identifier and body part corresponding to the body characteristic information matched with the first body characteristic information as the first user identifier and the first body part respectively, so as to determine shooting processing operation corresponding to the first body part, and executes the determined shooting processing operation on the first user identifier.

[0107] For example, the image recognition device determines a life value difference corresponding to each body part, and reduces the life value of the first user identifier according to the life value difference corresponding to the first body part when determining the first user identifier and the first body part. Herein, the life value differences corresponding to different body parts may be the same or different, the life value difference corresponding to each body part may also be determined according to importance of the body part. The corresponding life value differences are greater if the body parts are more important, and the corresponding life value differences are smaller if the body parts are more unimportant.

[0108] For example, the preset threshold value is 1, a life value difference of the head is 100, a life value difference of the trunk is 20, a life value difference of the arms is 10 and a life value difference of the lower limbs is 5. An initial life value of the game user is 100 at the beginning of the game. If the head of the game user is photographed, the life value is reduced based on the life value difference 100 of the head and thus the remaining life value is 0. The game right of the game user is directly disabled. If the trunk of the game user is photographed, the life value is reduced based on the life value difference 20 of the trunk and thus the remaining life value is 80. When the life value is reduced to be 0 after the game user is subsequently photographed for many times, the game right of the game user is disabled.

[0109] It is noted that the game user may play the game for many rounds but a validity duration of the game right is only one round. That is, after the game right of a certain game user is disabled, the game user may not play the game in this round, but the game right of the game user may be enabled again at the beginning of the next round of the game after this round of the game ends, and at this time, the game user may rejoin the game.

[0110] In addition, a user identifier for login of the image recognition device which takes the picture to be matched is employed as a second user identifier, and then shooting completion operation may also be executed on the second user identifier when shooting processing operation is executed on the first user identifier. The shooting completion operation represents that any game user shooting another game user shall be subjected to "rewarding" operation, and may be determined according to the preset game rule, which is not limited in the embodiment.

[0111] For example, the shooting completion operation may include operation of increasing the life value, that is, the image recognition device increases the life value of the second user identifier after determining the second user identifier shooting the other game user. Moreover, the image recognition device may also increase the life value of the second user identifier according to the preset difference.

[0112] In addition, when the pre-established relationship includes the relationship among the user identifier, the body part and the body characteristic information, the image recognition device may also execute the shooting completion operation corresponding to the body part on the second user identifier according to the body part corresponding to the first body characteristic information of the picture to be matched.

[0113] That is, the image recognition device may determine shooting completion operation corresponding to each body part in advance, and shooting completion operation corresponding to different body parts may be the same, and may also be different. After determining the first body part which is shot, the image recognition device may determine the shooting completion operation corresponding to the first body part and execute the determined shooting completion operation on the second user identifier. For example, the image recognition device increases the life value of the second user identifier according to the life value difference corresponding to the first body part.

[0114] In addition, in the game process of the embodiment, an initial score may be allocated to each user identifier, and the score of each user identifier may be updated according to game data such as shooting times, hitting times and shot times of the user identifier. Correspondingly, the image recognition device may reduce the score of the first user identifier when determining the shot first user identifier, and may increase the score of the second user identifier when determining the second user identifier shooting the other game user. At the end of the current round of the game, a final score of each user identifier, i.e. a final score of each game user may be determined.

[0115] In the embodiment, the image recognition device is adopted for the shooting game. For example, in a game process in which user A and user B involve, each of user A and user B is equipped with an image recognition device, and performs photographing with the image recognition device before the game is started, and the image recognition devices store body characteristic information of each user. After the game is started, user A photographs user B to obtain a picture to be matched, the image recognition device determines that user B is shot, disables a game right of user B or reduces a life value of user B according to different photographed body parts of user B, and increases a score of user A.

[0116] From the above, according to the method provided by the embodiment, the relationship between the user identifier and the body characteristic information is pre-established, and during the game, the picture to be matched is taken, the first body characteristic information corresponding to the picture to be matched is acquired, the first user identifier corresponding to the first body characteristic information is determined according to the relationship, and shooting processing operation is executed on the first user identifier. According to the embodiment, the image recognition device is adopted to simulate a simulative gun required in the game and a manner of taking the picture by the image recognition device is adopted to simulate a shooting action. Thus, multiple users may be equipped with image recognition devices respectively, and if a certain user is photographed, it is indicated that the user is shot. A special simulative gun is not required to be equipped in the game, so that limits of simulative guns are broken, and flexibility is improved.

[0137] Fig. 6 is a flow chart showing an image recognition method for a game, according to another exemplary embodiment. As shown in Fig. 6, the image recognition method for the game is applied to a server and a terminal, and includes the following steps.

Step 601: the terminal photographs at least one game user to obtain at least one picture of the at least one game user respectively, and sends the at least one picture to the server.
Step 601 is similar to operation of photographing with the image recognition device in Step 201, and will not be repeated here.

[0138] Step 604 to Step 606 are similar to operations of acquiring the first body characteristic information by the image recognition device in Step 204 to Step 206, and will not be repeated here.

[0139] In addition, after executing the shooting processing operation, the server may send a prompting message to the terminal which takes the picture to be matched and the prompting message is displayed by the terminal which takes the picture to be matched to prompt that shooting processing operation over a shot game user has been completed to a current game user. Alternatively, the server may also send the prompting message to the terminal corresponding to the first user identifier, and then the terminal corresponding to the first user identifier displays the prompting message to prompt that the shooting processing operation over the shot game user has been completed.

[0140] For example, the server sends a game right disabling message to the terminal corresponding to the first user identifier when disabling a game right of the first user identifier, and the terminal corresponding to the first user identifier displays the message to prompt that the current round of the game ends for the game users.

[0141] In the embodiment, the terminal and the server are adopted for the shooter game. For example, there are multiple game users, and a terminal of each game user logs in the server. Before the game starts, each game user takes own picture to obtain own image data such as clothes and body postures at any angle with own terminal, and uploads the taken pictures to the server on the basis of a login user identifier. The server performs characteristic extraction on the pictures uploaded by each terminal to obtain body characteristic information of each game user, and establishes the relationship between the user identifier and the body characteristic information. After the game starts, the game users photograph target game users with the terminals, and upload the obtained pictures to be matched to the server. The server performs characteristic extraction on the pictures to be matched to obtain the first body characteristic information, and compares the first body characteristic information with the body characteristic information of each game user, thereby determining which game user is shot.

[0142] From the above, according to the method provided by the embodiment, the relationship between the user identifier and the body characteristic information is pre-established, and during the game, the server may acquire the first body characteristic information corresponding to the picture to be matched by receiving the picture to be matched, determine the first user identifier corresponding to the first body characteristic information according to the relationship and execute shooting processing operation on the first user identifier. According to the embodiment, the terminal is adopted to simulate a simulative gun required in the game, and a manner of taking the picture by the terminal is adopted to simulate a shooting action. Thus, multiple users may be equipped with terminals respectively, and after the pictures taken by the terminals are uploaded to the server, the server performs image processing to indicate that a certain user photographed by the terminal is shot. A special simulative gun is not required to be equipped in a game process, so that limits of simulative guns are broken, and flexibility is improved.

[0143] The embodiment is described with respect to the condition that Step 601 and Step 603 are executed by the terminal and Step 602, Step 604 and Step 605 are executed by the server as an example. In addition, according to different parties for executing each step, the method may further include the following three conditions.

The terminal executes Step 605 according to the first body characteristic information to send the first user identifier corresponding to the first body characteristic information to the server, and then the server executes Step 606 according to the first user identifier to execute shooting processing operation on the first user identifier.
    Before the game starts, the terminal of each game user may perform characteristic extraction on the pictures are taken to obtain the body characteristic information of the corresponding game user, establish the relationship between the login user identifier and the body characteristic information and upload the relationship to the server. The server summarizes the relationship uploaded by each terminal to obtain the relationship including the user identifiers and body characteristic information of all the game users, and sends the relationship to each terminal. Each terminal stores the relationship. After the game starts, each game user photographs the target game user with the terminal, and uploads the obtained picture to be matched to the server. The server performs characteristic extraction on the picture to be matched to obtain the first body characteristic information, and sends the first body characteristic information to the terminal. The terminal compares the first body characteristic information with the stored body characteristic information to acquire the first user identifier corresponding to the body characteristic information matched with the first body characteristic information, and sends the first user identifier to the server. The server determines which game user is shot according to the first user identifiers.
  2. 2. Each terminal executes Step 601 to send the taken pictures to the server. The server executes Step 602 to establish the relationship between the user identifier and body characteristic information of each game user and send the relationship to each terminal. Each terminal stores the relationship. Then, any terminal executes Step 603 to 605 to acquire the first user identifier corresponding to the picture to be matched according to the stored relationship and send the first user identifier to the server. The server executes Step 606 according to the first user identifier to execute shooting processing operation on the first user identifier.
    Before the game starts, the terminal of each game user may perform characteristic extraction on the pictures which are taken to obtain the body characteristic information of the corresponding game user and establish the relationship between the login user identifier and the body characteristic information, and upload the relationship to the server. The server summarizes the relationship uploaded by each terminal to obtain the relationship including the user identifiers and body characteristic information of all the game users, and sends the relationship to each terminal. Each terminal stores the relationship. After the game starts, each game user photographs the target game user with the terminal. The terminal performs characteristic extraction on the picture to be matched to obtain the first body characteristic information, compares the first body characteristic information with the stored body characteristic information to acquire the first user identifier corresponding to the body characteristic information matched with the first body characteristic information, and sends the first user identifier to the server. The server determines which game user is shot.
  3. 3. Each terminal executes Step 601 to send the pictures are taken to the server. The server executes Step 602 to establish the relationship between the user identifier and body characteristic information of each game user. Then, any terminal executes Step 603-604 to acquire the first body characteristic information corresponding to the picture to be matched and send the first body characteristic information to the server. The server executes Step 605-606 to determine the first user identifier corresponding to the first body characteristic information and execute shooting processing operation on the first user identifier.


[0144] Before the game starts, the terminal of each game user may perform characteristic extraction on the pictures which are taken to obtain the body characteristic information of the corresponding game user and establish the relationship between the login user identifier and the body characteristic information, and upload the relationship to the server. After the game starts, each game user photographs the target game user with the terminal, and the terminal performs characteristic extraction on the picture to be matched to obtain the first body characteristic information, and sends the first body characteristic information to the server. The server compares the first body characteristic information and the body characteristic information of each game user to acquire the first user identifier corresponding to the body characteristic information matched with the first body characteristic information, and determines which game user is shot according to the first user identifier.
