PROBLEM TO BE SOLVED: To precisely track an object, regardless of presence/absence of an occlusion, while protecting privacy of the object, by using only a depth video.SOLUTION: An object detection part 10 detects objects on a depth video. An object curve extraction part 30 extracts object curves along left and right contours of the objects, respectively. An occlusion processing part 61 determines an occlusion between objects and manages an ID of the object in which the occlusion may be present, and presence/absence of the occlusion. An ID allocation processing part 40 determines correspondence of each object based on object curves of each object before occurrence of the occlusion and after dissolution of the occlusion, then allocates the same ID to the corresponding objects. A second occlusion dissolution time allocation part 43 allocates the same ID to the objects in which, similarity of the object curves before occurrence of occlusion and after dissolution of the occlusion, exceeds a predetermined threshold value.SELECTED DRAWING: Figure 1 |
