摘　　要：目前基于视觉的车辆轨迹提取易受光照、动态背景等环境的影响,且视觉无法实现区间内多目标速度的实时检测,故提出基于毫米波雷达的车辆行为检测。首先,利用毫米波雷达探测感兴趣区域(ROI)内车辆方位和速度信息,依据ROI内车辆行驶轨迹分布和速度状态判定车辆驾驶行为,最后制定合理的检测算法。实验结果表明,该算法可有效区分双车道内正常行驶车辆与违规车辆,能够快速准确地检测车辆逆行、变道、超速和掉头等违规行为。At present,vehicle trajectory extraction based on vision is vulnerable to the influence of light,dynamic background and other environments,and vision cannot realize real-time detection of multi-target velocity in the interval.Therefore,vehicle behavior detection based on millimeter wave radar is proposed.Firstly,the millimeter wave radar is used to detect the vehicle orientation and speed information in the ROI,and the vehicle driving behavior is determined according to the vehicle trajectory distribution and speed state in the ROI,and finally a reasonable detection algorithm is developed.The experiment results show that the algorithm can effectively distinguish normal vehicles from illegal vehicles in dual lanes.This design can quickly and accurately detect the vehicle retrograde,lane change,overspeed and u-turn violations.
