Summary:The invention relates to a light source detection method based on image processing. Acquiring corresponding grayscale images of the shot object under different degrees of light sources; dividing each gray-scale image into a plurality of gray-scale image blocks, calculating the mutation degree of each pixel point in each gray-scale image block, and further obtaining an estimated noise point in each gray-scale image block; replacing the gray value of the estimated noise point with the gray replacement value to obtain an estimated image block corresponding to each gray image block; obtaining a singular value threshold value corresponding to each gray level image block; carrying out denoising operation on each grayscale image block based on the singular value threshold to obtain a denoised image block corresponding to each grayscale image block; splicing the de-noised image blocks to obtain de-noised images corresponding to the grayscale images; and judging the number of noise points in each grayscale image accor
