The invention provides an unmanned aerial vehicle aerial photography ground target positioning method and system. The method comprises the following steps: detecting a target in an image by using a target detection model to obtain a central point coordinate of the target on the image so as to determine a target pixel position of the target in a pixel coordinate system; wherein the image is obtained from video data of a ground target aerially photographed by an unmanned aerial vehicle; acquiring state information of the unmanned aerial vehicle and state information of a camera holder; and inputting the state information of the unmanned aerial vehicle, the state information of the camera holder and the target pixel position into a target positioning model to obtain longitude and latitude information of the target. The unmanned aerial vehicle aerial photography ground target positioning method provided by the invention can be suitable for real-time positioning tasks of various general unmanned aerial vehicles on the ground target, target positioning under various focal segments and multiple angles can be completed, the cost is effectively reduced, and meanwhile, the positioning accuracy and efficiency of the ground target are improved.

    本发明提供一种无人机航拍地面目标定位方法及系统。该方法包括:利用目标检测模型对图像中的目标进行检测,得到所述目标在图像上的中心点坐标,以确定所述目标在像素坐标系中的目标像素位置;其中,所述图像是从无人机航拍地面目标的视频数据中获取的;获取无人机的状态信息和相机云台状态信息;基于所述无人机的状态信息、所述相机云台状态信息以及所述目标像素位置输入到目标定位模型,获得所述目标的经纬度信息。本发明提供的无人机航拍地面目标定位方法,能够适用于各类通用无人机对地面目标的实时定位任务,可完成各焦段、多角度下的目标定位,有效降低了成本,同时提高了对地面目标的定位精确及效率。
