Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/019076
Kind Code:
A1
Abstract:
Provided is an information processing device that tracks a specific object from images captured at a plurality of times. The information processing device is provided with: a retention means that retains a feature amount of a tracking target on the basis of a learned model that detects the position of a predetermined object in an image that has been input; an acquisition means that acquires feature amounts of objects in a plurality of images on the basis of the learned model; a detection means that detects a candidate object similar to the tracking target on the basis of the feature amount of the tracking target and the feature amounts of the objects acquired from the plurality of images; and an identification means that identifies a correspondence relationship between the candidate object detected in a first image among the plurality of images and the candidate object in a second image captured at a time different from that of the first image.
