The invention discloses a vehicle delay time calculation method and system based on thunder-vision fusion. The method comprises the following steps: acquiring video image data and radar detection data; performing data fusion on the video image data and the radar detection data to obtain relative space-time information of each vehicle relative to the intersection, and obtaining absolute space-time information of all vehicles at the intersection according to the relative space-time information; acquiring traffic timing information of the intersection, and classifying absolute space-time information of all vehicles at the intersection according to the traffic timing information to form a free flow vehicle class; according to the absolute spatio-temporal information corresponding to each free flow vehicle in the free flow vehicle class, obtaining standard passing time corresponding to the intersection; according to the absolute space-time information of all the vehicles at the intersection, the actual vehicle driving time of each vehicle is obtained; and obtaining the delay time of each vehicle according to the standard passing time and the actual driving time of the vehicle.
本申请公开一种基于雷视融合的车辆延误时间计算方法以及系统。方法包括:获取视频图像数据与雷达探测数据;将视频图像数据与雷达探测数据进行数据融合,获得每个车辆相对于交叉路口的相对时空信息,并根据相对时空信息获得交叉路口的所有车辆的绝对时空信息;获取交叉路口的交通配时信息,根据交通配时信息,对交叉路口的所有车辆的绝对时空信息进行分类,形成自由流车辆类;根据自由流车辆类中每个自由流车辆对应的绝对时空信息,获得交叉路口对应的标准通过时间;根据路口的所有车辆的绝对时空信息,获得每个车辆的车辆实际行驶时间;根据标准通过时间与车辆实际行驶时间,获得每个车辆的延误时间。
