In order to improve the calculation efficiency in the process of image disposal for children's vehicle distortion,Hough transform was optimized.First,the continuous search was melted with the Hough transform,and the oversize less size outline of the image was filtrated,at same time the continuous outline obtained was screened.By this way,the points participating in the Hough transform might be decreased.Second the information in the continuous transform was maximized in application to change the whole diagram searches into the partial element search,which reduced the search range consumedly.Experiment shows:compared with the Primitive Hough transform,the calculation efficiency of the Hough transform melted with the continuous search is 13times of the original Hough and the calculating speed of optimized Hough transform melted with continuous search is 497times of the original.Thus a good result is obtained.
