Abstract:
To ensure revulsive driving of intelligent vehicles at intersections, a method is presented to detect and recognize the traffic lights.First, the stabling siding at intersections is detected by applying Hough transformation.Then, the colors of traffic lights are detected with color space transformation.Finally, self-associative memory is used to recognize the countdown characters of the traffic lights.Test results at 20 real intersections show that the ratio of correct stabling siding recognition reaches up to 90%;and the ratios of recognition of traffic lights and divided characters are 85% and 97%, respectively.The research proves that the method is efficient for the detection of stabling siding and is robust enough to recognize the characters from images with noise and broken edges.
