The Design Of Interactive Vehicle Vision System For Safety Driving Assist

Intelligent vehicle vision of auxiliary driving system can detect obstacle to find out the potential danger to vehicle driving, and make the vehicle brake away from it. The Ethernet interface and initiator mode design of intelligent vehicle vision system is discussed in detail.In this paper, we perform primary research on Safety Driving Assist. Some problems of the latest intelligent vehicle vision system in the world such as complex structure, non real-time and low transfer speed are existed. Therefore, this paper proposes a real time video platform design scheme based on DSP. And it is made up of high performance TMS320C6204 acted as the system core, PCI I/O accelerator PCI9054 and Ethernet controller DM9000A with programmable logic CPLD to implement PCI initiator configuration and high speed dada exchange.Moreover, video control program to detect moving target is designed, including three buffer strategy control and the self-adapting background updating algorithm. The program's simulation and analysis are also provided to prove it effective. At last, the thesis describes the application prospect of the system.
