%X For the problem of the boundaries of the license localization being not correct and existing many non-license plate regions, the paper proposed a new framework of precise license plate localization combined edge analysis and color statistics. The framework included four parts, preprocessing, coarse positioning, precise positioning and non-license plate rejection. Firstly, this method carried out preprocessing such as edge detection and binarization, then adapted the method of projection to located some candidate regions coarsely, after that, analysed edge and color information in and around candidate region to rea-lize the precise locating. For the situation of existing more than one candidate regions, the method sorted the candidate regions, then passed the sorted regions to the character segmentation module, it could effectively eliminate the influence of non-license plate.Experiment results show that the method is highly accurate and precise, high real-time, adapting to different situations.
