The invention relates to a plane intersection traffic investigation method and system based on an unmanned aerial vehicle video, and the method comprises the steps: firstly carrying out the photographing of an investigated plane intersection through an unmanned aerial vehicle, obtaining a video, extracting the vehicle track information in the video through a computer vision technology, extracting the corresponding road structure information from the vehicle track information, and carrying out the calculation of the road structure information. And finally, building a simulation road network by using the extracted vehicle track information and road structure information, restoring an actual road scene, and realizing traffic investigation of the plane intersection. Compared with a traditional traffic investigation method, the method is simpler, manpower and material resources are saved, more visual, intelligent and large-scale plane intersection traffic information can be obtained, and technical support can be provided for follow-up establishment of a traffic demand prediction model and formulation of a reasonable traffic management plan.

    本申请涉及一种基于无人机视频的平面交叉口交通调查方法及系统,首先利用无人机对调查的平面交叉口进行拍摄获取视频,其次利用计算机视觉技术提取视频中的车辆轨迹信息,再次从车辆轨迹信息中提取对应的道路结构信息,最后利用提取的车辆轨迹信息和道路结构信息搭建仿真路网,还原实际道路场景,实现对该平面交叉口的交通调查。本申请相较于传统的交通调查方法,更为简易,节省人力物力,可得到更加可视化、智能化、规模化的平面交叉口交通信息,可为后续建立交通需求预测模型与制定合理的交通管理规划提供技术支持。
