Abstract
A disparity calculation apparatus for a stereo camera implements ranging of an object that includes consecutive similar patterns. In stereo matching, if a plurality of corresponding point candidates are present in a sum of absolute differences or similar evaluation value distribution for a target point, an evaluation value map is generated by superimposing an evaluation value distribution of a target point, for which a plurality of corresponding points are determined to be present, and an evaluation value distribution of each other target point present in a peripheral area of that target point. The shape of an object is represented in real space around a target point for which a plurality of corresponding points are determined to be present. The true distance of a railing that extends in a straight line is determined by extracting a line segment with the strongest linearity in the evaluation value map.
