(54)A COMPUTER-IMPLEMENTED METHOD, A COMPUTER PROGRAM PRODUCT, AND AN APPARATUS FOR FACILITATING PLACEMENT OF A SURVEYING TOOL


(57) A computer-implemented method of a mobile device for facilitating placement of a surveying tool, such as a rover rod is disclosed. The method comprises capturing (110), by a camera (14), at least one image (28) of surroundings; generating (120), by the mobile device (20), a representation (300) of the surroundings, based on the at least one captured image (28); creating (130), by the mobile device (20), a model (310) of the surveying tool (10) based on an estimation of a diameter and/or a length of the surveying tool (10) from a lockup table with known diameters and/or lengths of surveying tools, thereby producing a virtual surveying tool (312); receiving (140), by the mobile device (20), a model (320) of survey-related data, the survey-related data identifying a placement area/point (52) for the surveying tool (10); calculating (150), by the mobile device (20), respective mappings (32, 33) of the model (310) of the surveying tool (10), based on the position of the placement area/point (52), and of the model (320) of survey-related data to the representation (300) of the surroundings, based on sensor data from an electronic receiver (12) detachably attached to the mobile device (20), and based on sensor data from an inertial measurement unit, IMU, (16), the sensor data being associated with the at least one image (28) of the surroundings, thereby aligning the models (310, 320) with the representation (300); augmenting (160), by the mobile device (20), the representation (300) of the surroundings by superimposing the mappings (32, 33) onto the representation (300) of the surroundings, thereby producing at least one augmented representation (330); and displaying (170), by a display device (18), the at least one augmented representation (330). Corresponding apparatus and computer program product are also disclosed.
