The Intelligent transportation system is a real-time, accurate and efficient integrated transportation management system, with the LPR(License Plate Recognition) as one of its key technologies. In order to realize the real-time detection of license plate in the embedded systems, the license plate detection, location and recognition technology based on TMS320DM642 are studied. This paper proposes a kind of license plate location algorithm by combining texture detection with the Adaboost classifier. The system design combining with DM642 is based on EMCV and Opencv image processing library to come true coding porting. The system avoids the non-directional under the condition of only texture detection and the non-integrity under the condition of only Adaboost Classification, it also improves the accuracy of the positioning. In addition, the license plate image which has been located can be sent to the PC server by the TCP protocol. Then the license plate location and monitoring of remote vehicles can be realized.
