Abstract: A stereo vision image calibration method is applied to an image capturing device having a first image capturing unit, a second image capturing unit and an image rectify unit. The first image capturing unit and the second image capturing unit are arranged along a first direction. The first image capturing unit and the second image capturing unit are respectively utilized to acquire a first image and a second image. The image rectify unit rectifies the first image and the second image by a stereo vision parameter. The stereo image calibration method includes selecting the rectified first image and the rectified second image to compute a global disparity vector between the adjust image and the reference image, and if a vector component of the global disparity vector along a second direction which is different from the first direction has non-zero value, processing a stereo vision calibration according to the vector component.
