Document Type and Number:

WIPO Patent Application WO/2018/159775

Kind Code:

A1

Abstract:

Provided is an object tracking device that comprises: a superimposed image creation unit (C6) that creates a plurality of superimposed images (26) in which each of a plurality of images of untracked objects not including tracking object image characteristics is superimposed on a tracking object section image (23) that includes tracking object image characteristics (21); a discriminator creation unit (C9) that creates a discriminator by learning at least the image characteristics of the tracking object or the position thereof on the basis of the plurality of superimposed images (26); and a tracking object identification unit (C12) that, on the basis of the discriminator and a tracked image (28) that includes the image characteristics of the tracking object and of an obstacle, identifies at least the image characteristics of the tracking object or the position thereof in the tracked image (28). As a result of the foregoing, the object tracking device makes it possible for the location of the tracking object to be identified more easily without being affected by obstacles, as compared to the image tracking methods based on the template matching of the prior art.
