Example Embodiment

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0045] The embodiment of the invention discloses a method for positioning a tilted image of a drone, such as figure 1 As shown, the method includes:

[0046] Step S11: Obtain POS information of the tilted image of the drone;

[0047] It is understandable that in order to locate the tilted image of the drone, the POS information of the tilted image of the drone needs to be obtained first, because the POS information contains the position coor...

Abstract

The invention discloses a slanted image positioning method and system of an unmanned aerial vehicle. The slanted image positioning method comprises the steps that POS information of a slanted image ofthe unmanned aerial vehicle is acquired; the POS information is utilized to position the slanted image of the unmanned aerial vehicle to obtain a first position coordinate; a stereo satellite image is utilized to extract second position coordinate of a ground control point; the second position coordinate is utilized to optimize the first position coordinate, and a third position coordinate of theslanted image of the unmanned aerial vehicle is obtained. It is visible that in the slanted image positioning method, the ground control point is calculated by utilizing the stereo satellite image and the ground control point obtaining process in the prior art is omitted, so that the measurement cost during positioning of the slanted image of the unmanned aerial vehicle is greatly decreased. Accordingly, the invention also discloses a slanted image positioning system and system of the unmanned aerial vehicle, a medium and a device. Similarly, the system had the above advantages.

Description

technical field [0001] The invention relates to the field of remote sensing technology, in particular to a method, system, medium and equipment for locating oblique images of drones. Background technique [0002] With the continuous development of UAV technology, UAV (Unmanned Aerial Vehicle, UAV) is widely used in agricultural management, power line inspection and terrain mapping and other fields. The UAV oblique photography technology is to collect images from different angles such as vertical and oblique by carrying multiple sensors on the UAV platform, so as to provide powerful data guarantee for the establishment of various 3D models. However, due to the limited load capacity and high equipment cost of UAVs, there are generally no high-precision professional positioning and orientation sensors on the UAV platform. Therefore, in the existing technology, ground control points (GCPs) are generally used Points, GCPs) to locate the oblique image of the UAV. However, due to ...
