摘　　要：针对城市交通路口的多车道车辆数量统计问题,提出基于车道映射矩阵的车道划分方案。根据车道映射矩阵分布情况判断车道中心线位置,利用相邻车道中心线间的距离对车道进行划分,与车辆计数算法结合,实现多车道车辆计数系统。该方案能够减少环境因素对车道划分的影响,在白天与夜晚情况下均取得较好效果。实验结果表明,该方案准确率为93.6%,能够适应复杂道路,多车道实时车辆计数系统准确率能够达到91%以上,在保证系统实时性的基础上,提供了较高的系统准确性和鲁棒性。To solve the problem of multi-lane vehicle counting at urban traffic intersections,a lane division scheme based on lane mapping matrix was proposed.The position of the lane centerline was determined according to the distribution of the lane mapping matrix,and the lane was divided by the distance between the adjacent lane centerlines.The multi-lane vehicle counting system was realized by combining with the vehicle counting algorithm.The proposed scheme can reduce the influence of environmental factors,and achieves better results in both day and night situations.Experimental results show that the accuracy of the proposed scheme is 93.6%,which can adapt to complex roads.The accuracy of multi-lane real-time vehicle counting system can reach more than 91%,providing better performance on system accuracy and robustness on the basis of ensuring the real-time performance of the system.
