The embodiment of the invention discloses a traffic condition investigation and analysis method and system based on multi-data fusion, and relates to the technical field of multi-sensor fusion. The system is invented for realizing supervision, investigation and statistics of traffic conditions and is convenient to use. The method comprises the following steps: judging whether a target object enters a preset supervision area or not according to an interested area in fused data and data acquired by a millimeter wave radar; if yes, acquiring motion information of the target object, and assigning the target object as a globally unique ID so as to distinguish different target objects; determining an estimated position of the target object at the next sampling moment according to the motion information; acquiring high-precision point cloud information of the estimated position; acquiring high-definition image information of the pre-estimated position; and performing semantic analysis according to the high-precision point cloud information and the high-definition image information to obtain traffic abnormal condition information of the preset supervision area. The method is suitable for a road traffic condition supervision scene.

    本发明实施例公开一种基于多数据融合的交通情况调查分析方法及系统,涉及多传感器融合技术领域。为实现交通情况的监管与调查统计,便于使用而发明。该方法包括:根据融合数据中的感兴趣区域及毫米波雷达采集的数据判断是否有目标物进入预设监管区域;若有,则获取所述目标物的运动信息,并将所述目标物赋值为全局唯一ID,以区分不同的目标物;根据所述运动信息,确定所述目标物在下一次采样时刻的预估位置;获取所述预估位置的高精点云信息;以及获取所述预估位置的高清图像信息;根据所述高精点云信息和高清图像信息进行语义分析,得到预设监管区域的交通异常情况信息。本发明适用于道路交通情况监管场景中。
