| With the rapid development of our economy, car is more and more extensive spread to every corner of our life. However, traffic accident potential crises make us facing huge sense of urgency. There are many measures to avoid traffic accident happened, besides strengthen management, perfecting statutory and improve pilot quality, Using automobile electronic products in cars installation to improve road traffic safety has become the consensus of people. This research content is about lane departure warning system, this system has a decent role in avoiding the traffic accident caused by the driver's inattention.After investigation of domestic and foreign lane departure warning system development trend, we find domestic lane departure system research lagged far behind the abroad, the majority in algorithms and the relevant system hardware platform less. The main content of this paper is the whole platform's construction and related image processing algorithm in the validation work on the platform. By comparison, DaVinci experiment board Produced by Texas instruments was chosen as system based development platform. Then in the platform based on the design of the system, build the hardware framework, design the video acquisition module, the video image processing module and video display module. Then we design the system's hardware framework and software framework. On the basis of hardware platform, the structures of software development environment and the DaVinci system development process to do a detailed discussion.On the good foundation of system hardware and software platform, we made a video of real-time processing and storage test. In the test, we made smooth processing of image process and edge detection. In the platform, we made the classical algorithm test. So we find well filtering algorithm and edge detection algorithm to our platform, meanwhile we also proves this platform meet the system of performance requirements. Finally, we made depth research in the path real-time image storage, design the hard disk drive storage module, and realize the real-time storage of the road images. At last, we establish a solid foundation for the research. |
