Abstract
A calibration method of a stereo camera includes optionally setting a plurality of camera calibration parameters and a plurality of image rectification parameters of the stereo camera; executing an image capture step on at least one left eye pattern and at least one right eye pattern corresponding to each two-dimensional image of at least one two-dimensional image; generating a plurality of new camera calibration parameters according to a plurality of first images corresponding to all left eye patterns corresponding to the at least one two-dimensional image and a plurality of second images corresponding to all right eye patterns corresponding to the at least one two-dimensional image; and generating a plurality of new image rectification parameters of the stereo camera according to the plurality of new camera calibration parameters.
