[Abstract]:In today's society, automobile traffic accidents cause very serious injuries. Automobile manufacturers all over the world are committed to the research of automobile safety technology. The ideal state of automobile safety is zero accident death. The man-car-road cooperative intelligent transportation system will be able to achieve this ideal state. The vehicle safety driving assistant system based on panoramic vision is one of the key technologies of the "man-vehicle-road" link in the intelligent transportation system. The system uses electronic information technology to expand the driver's vision and make the driver better perceive the road environment. Reduce the incidence of traffic accidents effectively. This paper analyzes the research status of vehicle safety driving assistant system based on panoramic vision at home and abroad, aiming at the blank in the design and implementation of panoramic vision system platform in domestic universities and academies. How to design embedded digital information processing system platform to realize panoramic vision system is studied deeply. In this paper, "Nine Point" interpolation algorithm is designed, and the characteristics of panoramic vision system algorithm are studied. According to its characteristics, the Leonardo da Vinci technology of Texas Instruments Company is applied to the research and development of vehicle panoramic vision system. Research and design digital image processing system based on TMS320DM642 processor, make panoramic vision system platform, write the bottom code of panoramic vision system, after completing the integration of software and hardware, The laboratory simulation test and the real vehicle test of the vehicle safety driving assistant system are carried out. Through the laboratory simulation test and the actual vehicle test, the smooth and clear panoramic aerial vision image is obtained. The effect of the image shows that the design scheme based on Leonardo da Vinci technology has excellent performance in the application of the vehicle safety driving assistant system platform. The new "nine-point" interpolation algorithm designed in this paper takes up less hardware resources. The optimized Nine Point interpolation algorithm can greatly improve the smoothness of the image. The design and implementation of vehicle safety driving assistant system based on panoramic vision is successfully completed in embedded system.
