物体認識装置および物体認識方法
Document Type and Number:
Japanese Patent JP7434138
Kind Code:
B2
Abstract:
The problem to be solved by the invention is to accurately detect a distant object while preventing an increase in cost. An object recognition device includes: an imaging unit configured to acquire a plurality of thermal images having an object captured therein; a stereo matching unit configured to perform stereo matching using the plurality of thermal images and calculate a distance to the object; a specific temperature region extracting unit configured to extract a specific temperature region from the thermal images; and an area ratio estimating unit configured to estimate, based on the distance to the object calculated by the stereo matching unit, a ratio of an area of the object included in a pixel for the specific temperature region.
