Embodiment 1
[0035] With the rapid development of drone technology, drones are used in various fields. Usually, the UAV is equipped with a camera on the gimbal to obtain images, and the range finder installed on the UAV is used to measure the distance of the target in front, but there is no method for remote target positioning based on UAV ranging. In order to obtain the position of the target in the captured image, at present, the positioning technology based on the video image of the UAV is usually used to process the video image information collected by the camera in real time, and then compare the pixel position of the target in the video image with the map. By comparison, the position of the target can be found out. The position of the target obtained by this method not only has a large deviation, but also takes a long time to judge, the calculation process is complicated, and it is difficult to effectively obtain the accurate position of the target. In order to solve this problem, th...
