Abstract:

The license plate location is a key problem in the automatic recognition system of the license plate. More in-depth design did in two areas. Firstly, the video of the mobile vehicle positioning that mainly involved in the Gauss background modeling. Secondly, the static image of the license plate extraction system included the top hat transform, energy filtering, to find the area of the Unicom area and other modules to accurately locate the license plate region. The mobile license plate location algorithm using OpenCV and C++ programming is based on the QT platform to achieve a comprehensive use of the structure and texture features of the license plate, improving the reliability of the license plate location. Experimental results show that the method is faster and more accurate. The system can meet the needs of real-time monitoring.
