Abstract
The present invention provides a stereo camera in which it is possible to improve the precision of correcting vertical offset between a first image captured by a first image-capture unit and a second image captured by a second image-capture unit. In the present invention, an image-capture system unit 100a captures a benchmark image. An image-capture system unit 100b captures a reference image. A geometry correction unit 125 generates a plurality of geometry-corrected reference images having differing amounts of vertical-direction movement from the reference image. A parallax calculation unit 126 generates a plurality of parallax images from the combination of the benchmark image and each of the reference images. A parallax image evaluation unit 131 calculates evaluation values pertaining to the reliability of each of the parallax images. A vertical offset correction unit 132: calculates, on the basis of a correspondence relationship between vertical offset and the evaluation values pertaining to reliability, an evaluation value pertaining to the maximum reliability and a vertical offset that corresponds to this evaluation value; and sets the vertical offset that corresponds to the …
