The invention discloses a traffic state information acquisition method based on an unmanned aerial vehicle. The method comprises the steps of: acquiring a traffic condition video of a to-be-measured road section by using an unmanned aerial vehicle; performing image processing on the video acquired by the unmanned aerial vehicle to obtain related data; and calculating the traffic state informationof the to-be-measured road section with a floating vehicle method. According to the method of the invention, the advantages of low cost, flexible operation, small safety risk, wide coverage area and immunity to the limitation of road traffic of the unmanned aerial vehicle is are brought into full play, so that point, line and plane traffic detection from a local area to a wide area is achieved, and situations can be rapidly and efficiently controlled by a traffic management department.
本发明公开了一种基于无人机的交通状态信息采集方法,包括利用无人机采集待测路段交通状况视频;对无人机采集的视频进行图像处理得到有关数据;结合浮动车法计算待测路段的交通状态信息。本发明充分发挥无人机成本低、操纵灵活、安全风险小、覆盖区域广、不受道路交通限制的优势,实现从局部到广域的点、线、面交通检测,有利于交通管理部门快速、高效地控制局面。
