The invention discloses a landing method for tracking a moving vehicle based on an unmanned aerial vehicle visual system, belongs to the field of unmanned aerial vehicle landing control, relates to a visual image processing technology, and solves the problems that in a landing scheme for tracking the moving vehicle based on the unmanned aerial vehicle visual system, how to make a marker simpler and how to make the marker more accurate if a machine algorithm is broken through. The problem of how to prevent the unmanned aerial vehicle from landing to other illegal landing positions is solved; comprising the steps of placing a marker at a landing position; a landing instruction is obtained, and the unmanned aerial vehicle descends to a first flight height range; analyzing the license plate number image of the current moving vehicle, and determining whether the current moving vehicle is a target moving vehicle; the moving video image of the target moving vehicle is analyzed, and the unmanned aerial vehicle is controlled to move to the position over the target moving vehicle in an airborne mode; the marker of the landing position of the target moving vehicle is analyzed, and the unmanned aerial vehicle is controlled to land to a second flight height range; and further analyzing and processing the marker image of the landing position so as to control the airborne precise landing of the unmanned aerial vehicle.
本发明公开了基于无人机视觉系统下的追踪移动车辆的降落方法,属于无人机降落控制领域,涉及视觉图像处理技术,解决了基于无人机视觉系统下的追踪移动车辆的降落方案中,如何让标识物更加简单,若机器算法被攻破后,如何防止无人机降落至其他非法降落位置的问题;包括:在降落位置放置标识物;获取降落指令,无人机机载下降至第一飞行高度范围;分析当前移动车辆车牌号图像,确认其是否为目标移动车辆;分析目标移动车辆移动视频图像,控制无人机机载移动至目标移动车辆的正上方;分析目标移动车辆的降落位置的标识物,控制无人机机载降落至第二飞行高度范围;对降落位置的标识物图像进行进一步的分析处理,从而控制无人机机载精准降落。
