【摘要】：在智能交通系统(ITS)技术应用领域,如何根据道路车辆实时拥堵状态自动调整交通信号显示是实现智能交通的一个重要内容。然而,由于道路检测场景的复杂性,以及车辆之间互相遮挡、阴影、积水或昼夜转换等因素的影响,使得通过图像处理方法获得道路车辆排队数量,并基于嵌入式系统设计实现智能交通信号控制系统就成为一个有意义的实际课题。基于嵌入式的交通控制系统在扩展功能、减小系统体积、降低功耗和成本、提高控制实时性及稳定性等方面有无可比拟的优点,因此研究基于图像处理算法的嵌入式智能交通信号控制系统具有很大的实际意义。课题“基于图像处理算法的嵌入式交通信号控制系统的研究与设计”旨在以嵌入式S3C2440芯片和相关外围硬件构建一个嵌入式交通信号控制系统,将摄像头采集的道路车辆图像经过相关图像处理算法处理后获得排队车辆轮廓特征等信息及具体车辆个数,作为嵌入式交通信号控制系统的判断依据。论文主要二[作是在该系统上完成了Linux3.10.42内核编译及移植、文件系统构建、驱动编译及移植、软件层各接口函数以及主函数的编译实现。系统依据图片处理结果能够实时调控红绿灯显示时间,使交通信号能够实时高效的规制交通,达到提高交通道路通行率的目的。
[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.
