摘　　要：文中设计了基于机器视觉的行车环境安全预警系统,采用包含视频图像采集、行车环境检测以及行车环境安全预警3个功能模块的系统结构,重点研究并提出了新的行车环境识别方法,包含车道线提取和前方车辆检测方法,并对系统硬件架构及软件流程和算法进行说明,实现高速公路行车环境的识别并进行危险警示。实验结果显示,系统能够准确地对前方车道线和车辆进行检测,实现设计效果。This thesis aims to design a traffic environment prewarning system which is based on monocular vision and consists of three modules including CCD image acquisition module,driving environment detection module,and traffic environment danger alert module. The research focuses on new methods of traffic lane line extraction--preceding vehicle detection and traffic environment recognition,and also make description of the system hardware architecture and software process and algorithm,which can identify the highway traffic environment and warn drivers in case of dangerous situations. Experimental results show that the system can detect front lane and vehicles accurately to achieve the design effects.
