Design And Realization Of Vision Navigation System Based On SOPC

This essay do the research mainly in the field of Vision-based Navigation System. As an important section of this field, the research and development of the Intelligent Automatic Vehicle Driving Simulation Technique (IAVDST), paves a broad prospect for the improvement of transportation envirionment, the enhancement of vehicles'safety and reliability, as well as the reduction of traffic accidents caused by human factors.In this paper, the Intelligent Vehicle System is designed in there parts, i.e. the video capture part, the image processing part, the object recognition part and the controlling part.In the first part, we use the cmos to capture the analog image,transform the analog image to digit image by the saa7111 from Philips company,use the FPGAas the main chip; in the second part, graying processing, median filtering, Sobel edge detection, threshold segmentation and mathematical morphology are applied to process the image collected by the camera; in the third part, the road shape based algorithm and the improved template matching method are applied respectively for the road edge recognition and traffic light recognition; in the fourth part, the controlling method and the hardware design and realization of the imtelligent vehicle are introduced in this thesis. Finally, refering to some deficiency in the designing process, some suggestions are proposed, and the prospect is also viewed for the IAVDST.
