STEREO CAMERA DISPARITY CORRECTION

A measuring device (50) includes an acquisition unit (500) configured to obtain at least one pair of stereo captured images captured by a stereo camera (6), a detection unit (503) configured to detect two or more feature points from each one of the at least one pair of stereo captured images, and a measuring unit (506) configured to measure a disparity error using a distance between a pair of feature points of the two or more feature points detected by the detection unit (503) on each one of the at least one pair of stereo captured images, where an equation S img > ΔS E da d is satisfied. In the equation, S denotes the distance, and ΔS denotes a detection error between the pair of imaging devices (601R, 601L). Moreover, E denotes precision of measurement of a disparity error in disparity between a pair of images of the at least one pair of stereo captured images, and d denotes the disparity. The stereo camera (6) including a pair of imaging devices (601R, 601L).
