Described are methods and apparatus for adjusting images of a stereoscopic image pair based on keypoint matches. The quality of the key point matches is first evaluated to determine whether the quality exceeds a keypoint quality threshold. If the quality level of the keypoint matches exceeds the threshold, the vertical disparity between the images of the stereoscopic image pair can be evaluated based on vertical disparity vectors between the keypoint matches. If the vertical disparity is below a threshold, no adjustment of the stereoscopic image pair may be performed. If the vertical disparity is above the threshold, an affine correction may compensate for pitch, roll, and scale differences between the images. A projective correction may compensate for yaw differences. The vertical disparity between the two images is then evaluated after the corrections to determine if additional adjustment should be performed.
