| 摘 要： | 针对交通冲突传统人工判读方法的缺陷,提出了基于视频处理的无信号交叉口交通冲突自动判别方法。首先,利用运动检测与跟踪技术,提取出图像中的前景运动目标及其时空运动轨迹;其次,在获取物体运动数据与类别的基础上,判别物体的运动行为,结合经典冲突理论定义,提出交通冲突的两个判别条件,以此实现交叉口交通冲突的自动判别。通过对实际无信号交叉口视频图像处理的实验表明,本方法具有较好的应用性。

| Abstract: | For the defects of traditional artificial recognition and record method of traffic conflict,traffic conflict automatic discrimination at non-signalized intersection based on video processing is presented in this paper.Firstly,foreground moving objects in the image and their spatial and temporal trajectories are extracted by motion detection and motion tracking;and then,the motion behaviors are obtained based on objects types and moving data.Traffic conflict can be discriminated in terms of two traffic confl... |
