摘要: 为提高车辆前向防碰撞预警系统对前方道路环境感知的准确性,提出一种毫米波雷达与视觉传感器信息融合的车辆跟踪方法。提出的剔除雷达干扰目标算法缩短了对干扰目标的处理时间;提出的对称检测算法可对雷达目标兴趣区域进行对称检测,减小雷达目标兴趣区域的横向位置误差;提出的KCF-KF组合滤波算法可提高跟踪车辆的精度。实车试验表明,该方法可有效跟踪车辆位置信息,像素坐标系下的X、Y坐标跟踪准确率分别超过97.34%与95.19%。

Abstract: In order to improve accuracy of vehicle forward collision prevention warning system on road environment perception, a vehicle tracking method of information fusion for millimeter-wave radar and vision sensor was proposed. An algorithm to eliminate radar jamming targets was proposed to reduce processing time of jamming targets. A symmetric detection algorithm was proposed to detect radar target ROI (region of interest) symmetrically and reduce lateral position errors of radar target ROI. In order to improve the tracking accuracy, a KCF-KF combined filtering algorithm was proposed to track and fuse vehicles. Actual vehicle tests show that the method may effectively track vehicle position information, and the tracking accuracy of X and Y coordinates in pixel coordinate system is more than 97.34% and 95.19% respectively.

Key words: millimeter-wave radar, vision sensor, information fusion, vehicle tracking
