Apparatus, program, and method for tracking an object using a dedicated discriminator when occlusion occurs

摘要

PROBLEM TO BE SOLVED: To provide a device capable of immediately and accurately grasping the position of an object body and tracking it even if an occlusion occurs.SOLUTION: The present device capable of tracking a tracking object body using a time-series image group acquired by one or more cameras capable of photographing the tracking object body has: first body tracking means of tracking the body by identifying a region of the body in each image of a body identification object by a first identifying unit which learns the body using acquired images including the body; occlusion determination means of determining whether occlusion has occurred to the identified region of the body; and second body tracking means of tracking the body by identifying a part associated with the body in each image of the body identification object by a second identifying unit which performs learning about the body using an occlusion-excluding region which occlusion of the region of the body does not extends to when it is determined that the occlusion has occurred.SELECTED DRAWING: Figure 3
