Abstract: PROBLEM TO BE SOLVED: To provide a stereo camera system capable of solving the problem in the stereo camera system, ensuring corresponding point search between two images to thereby make deduction of a parallax value accurate, thereby increasing certainty of object shape recognition, and heightening its reproduction accuracy. SOLUTION: In this high precision stereo vision using a continuous frame image, plural pairs of stereo images from different viewpoints of a non- deformable object, and the corresponding point search having high correlation between each pair of images is executed to detect the parallax, and the object shape is operated from the parallax value, and the corresponding point search is executed similarly between each pair, and the object shape is operated, and data are accumulated, and overall operation of accumulated information is executed, to thereby ensure the object shape estimation value.
