The invention belongs to the technical field of traffic target recognition, and particularly relates to a signal intersection vehicle track repairing method based on a roadside laser radar. The objective of the invention is to solve the problems of wrong, lost and discontinuous vehicle trajectory tracking caused by the fact that the existing vehicle trajectory prediction method does not consider the signal phase change in the running process of a vehicle in a signalized intersection, whether there is a vehicle in front or not, the motion state of the vehicle in front and the like. According to the solution of the invention, based on roadside laser radar point cloud data, factors of signal lamps and vehicle queuing are considered, and a vehicle following model and a motion model are utilized to carry out track repair on vehicles with track interruption at different positions in a signalized intersection, so that the accuracy and continuity of track data are improved, and the accuracy of the signal intersection is improved. Therefore, high-precision and complete traffic flow trajectory data are provided for holographic sensing of road traffic flow, refined traffic signal control and accompanying traffic travel.

    本发明属于交通目标识别技术领域,具体涉及一种基于路侧激光雷达的信号交叉口车辆轨迹修复方法;本发明的目的在于解决现有的车辆轨迹预测方法未考虑车辆在信号交叉口内运行过程中信号相位变化、前方是否有车以及前车的运动状态等造成车辆轨迹跟踪错误、丢失、不连续等问题;本发明的解决方案主要以路侧激光雷达点云数据为基础,考虑信号灯、车辆排队的因素,利用车辆跟驰模型与运动模型,对信号交叉口内不同位置发生轨迹中断的车辆进行轨迹修复,以提高轨迹数据的准确性和连续性,从而为道路交通流全息感知、精细化交通信号控制、伴随式交通出行有道提供高精度、完整性交通流轨迹数据。
