| The rapid development of city modernization make demand of make demand of makes stronger demand of intelligent modern traffic,which means the Intelligent Traffic management System (ITS) has become the main platform in current urban traffic management. Embedded Technology combined with License Plate Recognition(LPR) is an important development field. On the other hand, the embedded Smart Camera has integrated image acquisition, image intelligent processing and network communication functions, using high performance embedded processor,which makes the power consumption of the system reducing and operation ability raising.A complete license plate recognition system consists of three parts:license plate area location, license plate character segmentation and character recognition. Starts from engineering applications, the thesis makes a detail study on optimization and transplant method of embedded license plate recognition system,and makes in-depth research on the key technology of character recognition.The main contents are as follows:1. Describe EagleEye 3 Smart Camera embedded development platform in detail,and research status of license plate recognition technology along with the current problems and difficulties.2. Accomplish embedded transplantation of license plate recognition system, and optimize license plate recognition algorithm based on Gabor filter.So enhancing the accuracy of recognition algorithm as well as reducing the. time-consuming.3. Use Local Binary Patterns algorithm in character recognition of license plate recognition. Maintaining the high character recognition accuracy at the same time, the average time is reduced greatly.4. The key technologies being used to implement and optimize license plate recongnition system and hardware optimization method based on Eagleeye3 smart camera were provided in detail. Realize the license plate recognition subsystem in electronic police system of intelligent integrated machine,linked with other modules in the system. |
