The invention discloses an intersection diversion line analysis method and system based on Leiyu fusion. Performing data fusion on the video image data and the radar detection data to obtain relative spatio-temporal information; obtaining absolute space-time information of all vehicles according to the map information and the relative space-time information; obtaining the actual track width of each vehicle according to the vehicle model and the vehicle width, obtaining the latitude and longitude of the actual track width according to the actual track width and the vehicle latitude and longitude, projecting the latitude and longitude to map information, and obtaining the simulated track width of each vehicle; taking the longitude and latitude of the vehicle at each moment as a central point, carrying out line segment extension for simulating the track width in the direction perpendicular to the direction angle of the vehicle to obtain a track at each moment, and connecting the end points of the tracks one by one to form a wheel track; carrying out thermodynamic diagram effect processing on the wheel track to obtain a wheel track thermodynamic diagram; and according to the longitude and latitude of the vehicle, transferring the wheel track thermodynamic diagram to map information for analysis, and judging whether diversion line drawing is correct or not.

    本申请公开一种基于雷视融合的交叉路口导流线分析方法以及系统。将视频图像数据与雷达探测数据进行数据融合,获得相对时空信息;根据地图信息与相对时空信息获得所有车辆的绝对时空信息;根据车辆型号与车辆宽度,获得每个车辆的实际车辙宽度,根据实际车辙宽度与车辆经纬度,获得实际车辙宽度的经纬度投影至地图信息中,获得每个车辆的模拟车辙宽度;以每个时刻的车辆经纬度为中心点,向垂直于车辆方向角方向进行模拟车辙宽度的线段延伸,获得每个时刻的车辙,将车辙逐个端点连接形成车轮轨迹;对车轮轨迹进行热力图效果处理,获得车轮轨迹热力图;根据车辆经纬度,将车轮轨迹热力图转移至地图信息中进行分析,判断导流线绘制是否正确。
