Proposed based on improved Sobel operator license plate location algorithm, first pre-processing of the license plate image has adopted the use of the improved Sobel operator to conduct operations, and then demand the use of iterative thresholds the image segmentation algorithm for optimal binarization car At last, the level of brand image projection and vertical projection algorithm to the analysis of the candidate region locking plate position.
