Abstract


With the rapid economic development , highway construction projects increasing road traffic safety operational issues become increasingly prominent. How to make road traffic management scientific and modern , intelligent road traffic management department has become the most important issue . Through in-depth study of the Highway Toll System in the vehicle license plate recognition system , speeding detection and alarm systems and image storage, transmission system , the image processing and models, license plate recognition algorithm and implementation ; analysis recognition of the basic models , design the composite model recognition system using infrared detectors piezoelectric transducers vehicles weighing meetings ; speeding detection alarm algorithm based on the video image detection technology ; designed road vehicles speeding detection and alarm of the hardware and software of the system ; in image processing , this paper proposes the use of large areas of softening an image DCT transform coding and strengthening the license plate parts of the image wavelet transform coding , combined with digital identification technology to generate a high compression ratio hybrid coding method . Thus solving many of the problems of the DVR storage and transmission of digital video processing . The focus of this study is to model, license plate recognition system design and implementation, speeding detection and alarm and digital video image compression and coding . Model and license plate recognition , this paper proposes the use of fuzzy template matching method to locate the vehicle license area , the method can be based on regional search and locate edge features license area . Vehicle detection , the use of digital video processing technology to achieve the speeding vehicle detection and alarm . This article analyzes the digital video image processing method in image processing , to create a model of the specific area of the digital video image processing program ; illustrates the basic structure of the digital video image compression coding method and the image processing method of the specific area ; proposed in the digital video image , an image processing method used for license plate recognition .
