The Vehicle License Plate Recognition And Speeding Detection Systems Based On Digital Image Processing

With the rapid economic development and highway construction projects is growing. Highway traffic safety problems operation is becoming more and more prominent. Highway traffic management how scientific,modern and intelligent traffic management has become the most important issue. It is based on the monitoring system of toll-road vehicle and license plate recognition system. Detection and Alarm System speeding vehicles, and image storage and transmission system of in-depth study, Image preprocessing and the models, algorithms and implementation of the LPR; Vehicle identification of the basic methods Piezoelectric sensors using infrared detector design + vehicles weighing you and the composite models identification system; Based on the analysis of the video image detection technology, the speeding vehicle detection algorithm reports, The design of the highway speeding detection and alarm systems; In image processing, This paper proposes the use of large-scale regional image weakening the DCT and strengthen parts of the wavelet transform image plates Addendum identification and integration of digital techniques to produce code with a high compression ratio of mixed coding method. Thus solving DVR storage and processing of digital video transmission problems. Is the focus of this paper models, license plate recognition system design and implementation Detection and Alarm speeding and digital video image compression and coding. In the vehicle and license plate recognition, fuzzy matching method is proposed in this paper for vehicle license regional location, Vehicle license can be based on the periphery of the regions rich features of the regional search and positioning. We are detection of the vehicles, using the digital video processing technology to achieve the speeding vehicle detection and alarm. In image processing, digital video image analysis of this basic approach established a special digital video image processing model and regional programs; Digital Video Image explained the basic structure and special regional coding methods and image processing; Digital video images in the image processing method for LPR.
