Research on License Plate Recognition Method Based on HALCON

With the rapid development and continuous improvement of image processing technology, intelligent management traffic system for vehicles has accelerated speed road safety information, in which car license plate as identification vehicle identity, its character information is key to recognition system. In order solve problem traditional algorithm such long period, this study adopts HALCON a programming platform, acquisition preprocessing enhance contrast, through affine transformation complete correction tilt image, at completion design after segmentation OCR based on neural network classifier accurate Chinese characters, letters Numbers. The experiment shows that ability adapt environment can recognize efficiently accurately.
