The Road Information Video Capture and Processing Research for Smart Car Based on CMOS Camera
In this paper,the road information collection systems and processing algorithms of video signal was researched based on vision sensor,the processor of Smart car used MC9S12XS128. The hardware part of capture system using the LM1881 as the sync signal segregator of video,the video signal through the internal MCU AD to sample. The key of Sample software system is to use the turn of double-array storage and processing technology,Image data through the median filter,the continuity of navigation lines and width determine to deal with,the final use the edge detection technology on the black navigation line to accurately detect the edge. This algorithm narrows the scope of edge detection so it greatly reduces the processing time, improve the reliability of detection.Experiments have proved that the algorithm has good real-time performance,reliability and robustness.
