Paper Abstract

In order to correct the distortion phenomenon of photoelectric image acquired by CCD camera because of bigger visual field, a correction method based on using bilinear interpolation to control rectangular grid interpolation in radial distortion model is proposed. The basic principle that corrects the image which has geometric distortion was analyzed in detailed. Firstly, the distortion correction model along the radial direction and the subsequent image processing are analyzed. After the preliminary correction, in order to correct the non integer position of the distorted image, the gray interpolation and curve fitting was given. Finally, so as to prove the correctness and validity of the basic principle analysis, a distortion correction experiment of photoelectric image acquired by CCD camera is actualized, the subjective and objective results are presented to validate the proposed method.
