Research And Realization Of License Plate Location And Segmentation Technique

License plate recognization(LPR) system is an important link in the realization of the Intelligent Transportation System(ITS),the research of LPR system has very important practical value.The LPR system consists of three modules in general,those are:License plate location,character segmentation and character recognization,and we mainly research the former two parts in this paper.In this paper we have summarized the lastest research achievements and development of license plate location and character segmentation. In the License plate location part,this paper presents a plate location algorithm based on HSV space.In the character segmentation part, the paper presents a algorithm based on projection method and template matching to segment characters. The experimental results indicate that the experimental algorithms in this paper can be adapted to complex background,and they are excellent in accuracy and robustness.
