A Kind of Vehicle Pressure Yellow Line Detection Algorithm Based on Wavelet Transform

For the Development of China's transportation industry, to develop video-based vehicle detection system prohibited the need for pressure line, the article compares and learns from the existing video surveillance technology on the basis of intelligent transportation system's analysis and research. According to distribution characteristic of central yellow line area roads, the article proposes the algorithm based on wavelet transform pressure line detection. It has more practical significance on achieving the testing about vehicles rolling pressure and the central yellow line area roads. Firstly, the central road of the yellow line is separated to narrow the scope of testing by wavelet transform technique for image segmentation; and then using image segmentation based on color histogram matching algorithm judges whether the vehicle is rolling and pressing the yellow line area. On this basis, we developed a prototype vehicle contraband detection system pressure lines, the results show that the success rate in detection, false detection rate and timeliness are superior to other algorithms, and better meets the needs of engineering practice.
