Method for processing CCD images

The invention relates to a method for processing CCD images. The method includes the steps that firstly, MATLAB software is utilized to simulate light spot images generated by CCD sensors on a highway, the light spot images are preprocessed, and median filtering is utilized to denoise laser spots generated through simulation; secondly, binarization processing is conducted on the images processed through the first step, wherein gray values of pixels on the images are set as 0 and 255 according to a designated threshold value, and through a CCD image measurement system light spot center locating method, the images on which binarization processing is conducted can present the obvious black and white effect, and the threshold value is selected based on the standard of reflecting the whole and local characteristics of the images; thirdly, a Gaussian Laplace operator is utilized to conduct edge extraction on the images processed through the second step. Light spot center locating is conducted on the images collecte
