| Abstract: | A method for detection and recognition of traffic lights based on intelligent vehicle mounted camera was proposed. Applying the threshold acquired by image training, the candidate regions of traffic lights are extracted using the color segmentation method. Next the concatenated filters are proposed as a way to classify the extracted candidate regions. And then template matching using normalized cross correlation techniques is adopted to validate the classified traffic lights candidates. The experimental results show that the proposed algorithm works effectively and robustly for traffic lights recognition for intelligent vehicles in complex urban environments. |
