Stereo Camera Apparatus
First Claim
1. A stereo camera apparatus which measures a distance to an object, using two images picked up by two cameras, comprising:
- an image capture unit which takes in the two images;
an image generating unit which changes resolution of a area of each image taken in by the image capture unit; and
a distance calculating unit which calculates a distance from the vehicle to an object that is imaged in the partial area, based on disparity of the partial area of each image in which resolution is changed by the image generating unit.

Abstract
A stereo camera apparatus which carries out distance measuring stably and with high accuracy by making measuring distance resolution variable according to a distance to an object is provided. A stereo camera apparatus 1 takes in two images, changes resolution of a partial area of each image that is taken in, and calculates a distance from a vehicle to an object that is imaged in the partial area, based on disparity of the partial area of each image in which resolution is changed. Thus, even when the object exists at a long distance and is small in size, distance measuring processing can be carried out stably.
