Abstract


With the rapid development of Intelligent Transportation, video-based vehicle detection technology becomes the focus of research in the world. Video-base vehicle detection technology gained rapid development because it can detect range and provide comprehensive traffic information and other advantages.Based on analysis and understanding of the embedded technology and video detection technology, proposed an embedded video detection system solution to detect the traffic flow on real-time.This paper describes a video system based on the ARM11 of S3C6410; this system is an embedded terminal equipment with the transplant of the Linux operating system. This equipment is placed on top of road, using its own camera as a video capture device to collect video data in the v412 (video for Linux two) programming model. The energy value of the current image is obtained in the real-time processing of video data and we can determine whether there is a car passing through by way of updating the energy value of the background frame, so as to achieve the purpose of traffic detection.
