Of the image feature point extraction problem. In the corner over the course of extraction, using the Harris corner detection algorithm, and the actual photos were corner extraction.3.Use svd factorization, through the camera when the image on the imaging point and the relationship between the real scene, the establishment of equations, using orthogonal projection ratio of the final determined outside the parameters of the camera.Key words: Camera calibration;Transform relationship between the coordinate system ;svd factorization algorit
