Abstract
A measuring device and a measuring system. The measuring device includes circuitry to obtain at least one pair of stereo captured images captured by a stereo camera, detect two or more feature points from each one of the at least one pair of stereo captured images, and measure a disparity error using a distance between a pair of feature points of the two or more feature points on each one of the at least one pair of stereo captured images, where an equation is satisfied. In the equation, Sdenotes the distance, Δ denotes a detection error between the pair of imaging devices. Moreover, Edenotes 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 including a pair of imaging devices.
