[Abstract]:In the application of Intelligent Transportation system (its) technology, how to automatically adjust the traffic signal display according to the real-time traffic congestion is an important content of its. However, because of the complexity of road detection scene and the influence of mutual occlusion, shadow, water accumulation or diurnal conversion between vehicles, the queue number of road vehicles can be obtained by image processing. And the design and implementation of intelligent traffic signal control system based on embedded system has become a meaningful practical issue. The traffic control system based on embedded system has unparalleled advantages in extending function, reducing system volume, reducing power consumption and cost, improving real-time control and stability, etc. Therefore, it is of great practical significance to study the embedded intelligent traffic signal control system based on image processing algorithm. The research and design of embedded traffic signal control system based on image processing algorithm aims to construct an embedded traffic signal control system based on embedded S3C2440 chip and related peripheral hardware. The road vehicle images collected by the camera are processed by the related image processing algorithm to obtain the information such as the contour features of the queuing vehicles and the number of the vehicles, which can be used as the judgment basis of the embedded traffic signal control system. The main work of this paper is to compile and transplant Linux3.10.42 kernel, build file system, compile and transplant driver, compile and implement interface functions and main functions in the software layer. According to the result of image processing, the system can control the time of traffic light display in real time, make the traffic signal can regulate the traffic in real time and efficiently, and achieve the purpose of improving the traffic rate.
