Abstract:
Because the PC based license plate recognition system has a high cost, heavy complex operation, security is low and many other defects, we proposed license plate recognition technology embedded monitor video license plate recognition and embedded together by median filter, Sobel edge detection, global thresholding,texture features based on the approximate location, character normalization, different classifier character recognition technology to form a complete license plate recognition system. The system is small, stable, practical and accurate. We conducted 900 patients with different license plate recognition experiment under different circumstances, the accuracy rate is as high as 97. 3%, and the system can achieve very high precision.
Key words: license plate recognition, embedded system, character normalization, sobel edge detection
