Based on the theory of true ortho rectification,this paper discussed the method in dealing with the occlusion areas of the image.Aiming at detecting and identifying the occlusion areas in true ortho rectification,a modified method based on Z-Buffer algorithm and threshold selection was proposed.The Z-Buffer algorithm was modified by dividing one image into four to do the rectification.Experiments showed that the modified method could realize true ortho rectification quickly and the result was with good effect.
