Abstract: Identification of digital traffic signals indicator is the process of analyzing image content based on the characteristics of digital indicator to identify, classify and recognize digital indicator target, including pretreatment, positioning, segmentation, identification and etc. This paper designs a more simple, accurate digital signal light recognition method by using the target detection algorithm based on the color-shape characteristics and the recognition algorithm based on BP neural network. Simulation experiments results show that this method is of higher accuracy rate and execution efficiency.

Key words: BP neural network, semaphores recognition, digital indicator
