Minimizing deformation geometric rectification of non-calibration stereovision

YANG Bi-wu ( The Second Artillery Equipment Academy, Beijing 100085, China )  
Projective transform in the process of image rectification produces under-sampling or over-sampling. To reduce deformation from image rectification, multi-type image deformation was studied emphatically. Firstly, a pair of images was normalized to simplify fundamental matrix, and the geometric constraint was applied to simplify rectification transform matrix. Secondly, the extremum of sum of projective transform weight change was solved to minimize projective distortion. Lastly, the rectification transform matrix was solved to minimize resampling effect which was weighed by Jacobian determinant. A planar rectification on epipolar geometry from the matrix could minimize the deformation including the projection distortion and the resampling effect.
