PROBLEM TO BE SOLVED: To provide a method, a device, and a program capable of correctly tracking an object regardless of the presence or absence of an occlusion, while respecting the privacy of an object using a depth video image only.SOLUTION: An object detection part 10 detects an object from a video (depth video) frame having depth data only. An object area setting part 20 sets a rectangular object circumscribed to or contained in the profile for each object. An ID allotment processing part 30 compares a position, a size, and a moving vector of each object between the video frames, and allots the same IDs with the objects exceeding a prescribed threshold value in similarity as the same objects. An occlusion determination part 41 determines that the occlusion is generated between objects A, B superposed with a portion of object areas Ka, Kb, and registers an ID intrinsic to the object in an occlusion list 4.SELECTED DRAWING: Figure 1 |
