| 摘 要： | 在对目前视频检测系统分析的基础上,针对交通事件检测,提出了一种从微观的角度出发,在对单个车辆交通行为状态识别和实时分析的基础上,对车辆交通安全状态进行判断的方法。首先对交通冲突冲突区进行动态和静态划分,然后将车辆行驶区域根据交通行为过程分为危险区和趋势区,并对应静态和动态冲突区分别对危险区和趋势区的判定进行分析,给出了判定算法。测试表明,本文所提算法能够在一定程度上对交通事故进行提前预警,对于减少和避免交通事故发生具有重要意义。

| Abstract: | Based on the analysis of current video detection system,a method to ssess vehicle safety status for traffic incident detection at microcosmic level according to the real-time analysis and identification of single vehicle behavior was put forward.First,traffic incident impact area was divided into static area and dynamic area,then the vehicle driving area was divided into dangerous area and trend area according to the process of traffic behaviors,and the algorithm to determine the dangerous area and trend ar... |
