ABSTRACT:
A target recognition apparatus that improves a recognition rate of a target by emphasizing vertical components of picked-up images, even if the target has a round shape of which the edges are is difficult to extract. The target recognition apparatus carries out the following processes. It compresses two images that have been simultaneously picked up with a left camera and a right camera that are mounted on a vehicle, in a lateral direction respectively. It detects both ends of the target in the two images, based on gradations of pixels in the images that have been compressed in this lateral direction. It measures a distance to the target, based on a parallax of the both detected ends of the target. A searching area of a target can be set based on the images compressed in a lateral direction.
