Calibration system for stereo camera

The invention discloses a calibration system for a stereo camera. The calibration system comprises a flat-screen liquid crystal display and perpendicular guide rails, wherein the perpendicular guide rails are symmetrically arranged on two sides in front of the flat-screen liquid crystal display; each perpendicular guide rail is provided with two sliding blocks which can move on the perpendicular guide rail; the side surfaces of the perpendicular guide rails are provided with threaded holes which are uniformly arranged at intervals; the sliding blocks are provided with through holes; bolts are arranged in the through holes in the sliding blocks in a penetration manner to be in threaded connection with the threaded holes in the perpendicular guide rails to fix the sliding blocks on the perpendicular guide rails; the sliding blocks are provided with the stereo camera; the flat-screen liquid crystal display displays a black card checkerboard grid pattern used for calibrating the stereo camera.
