Tri-level optimization-based image rectification for polydioptric cameras

作者：

Highlights：

• An image-rectification method for polydioptric cameras is proposed.

• It is based on an optimization that reduces the disparity error of correspondences.

• The disparity error was reduced by 66.57% compared with the conventional methods.

• Low x and y disparity errors were achieved in various types of images.
