IMAGE CALIBRATION SYSTEM AND CALIBRATION METHOD OF A STEREO CAMERA

摘要

A calibration method of a stereo camera includes controlling a left eye image capture unit and a right eye image capture unit of the stereo camera to execute an image capture operation on a calibration pattern with a plurality of feature points to generate a left eye image and a right eye image, respectively; extracting a plurality of first feature points and a plurality of second feature points corresponding to the plurality of feature points from the left eye image and the right eye image, respectively; calculating camera calibration parameters corresponding to extrinsic parameters of the stereo camera according to the plurality of first feature points, the plurality of second feature points, and intrinsic parameters of the stereo camera; and executing an camera calibration process on the left eye image capture unit and the right eye image capture unit according to the camera calibration parameters, respectively.
