The invention relates to an unmanned aerial vehicle fixed-point fire extinguishing method under a satellite positioning system denial condition. The method comprises the steps that ground image information is shot through a camera module according to a preset time interval, landmark points of the ground image information are recognized through an image recognition algorithm, and the landmark points are matched with landmark points pre-stored in a memory module; the initial position of the unmanned aerial vehicle at the current moment is obtained by communicating with a pre-deployed UWB base station, the current position information of the current unmanned aerial vehicle is obtained by adopting a three-point positioning method according to the initial position and a landmark point, and the unmanned aerial vehicle is controlled to fly to the target position according to comparison between the current position information and the target position. And the electronic ammunition is put for fixed-point fire extinguishing. By adopting the method, high-precision image transmission can be realized so as to support a fixed-point fire extinguishing task.

    本申请涉及一种卫星定位系统拒止条件下的无人飞行器定点灭火方法。所述方法包括:通过摄像头模组按照预设的时间间隔拍摄地面图像信息,通过图像识别算法识别所述地面图像信息的地标点,且与内存模块预先存储的地标点进行匹配;通过与预先部署的UWB基站进行通信,得到当前时刻无人飞行器的初始位置,根据初始位置以及地标点,采用三点定位法,得到当前无人飞行器的当前位置信息,以根据当前位置信息与目标位置进行比对,控制无人飞行器飞行至目标位置后,将电子弹药投放进行定点灭火。采用本方法能够实现高精度的图像传输,以支撑定点灭火任务。
