PROBLEM TO BE SOLVED: To reduce an operation quantity for searching for a corresponding point, and to determine the corresponding point accurately, when performing stereo matching. SOLUTION: The first distance image generation part 30 generates a distance image D1 from data for the distance image acquired by an imaging part 2A. A stereo matching part 31 detects the corresponding point from a standard image and a reference image acquired by imaging parts 2B, 2C, and the second distance image generation part 32 generates a distance image D2. In this case, a domain within a prescribed distance range based on a standard point determined on the distance image D1 is set as a searching range of corresponding points of the standard image and the reference image.
