Abstract
Provided is an object recognition device for detecting an object in an image, with which it is possible to detect, with high accuracy, a target object even in an image that has a background and other objects shown therein. This object recognition device is characterized by comprising: an image acquisition unit which acquires a first image composed of two-dimensional pixels; a three-dimensional shape approximation determination unit which determines whether image information of a prescribed rectangular region within the first image can be approximated by prescribed three-dimensional shape information; an image region estimation unit which clips out the rectangular region as a first estimation region on the basis of a determination result provided by the three-dimensional shape approximation determination unit; and a region selection unit which selects, from among a plurality of the first estimation regions, a first estimation region that has the smallest area.
