Slanted image positioning method and system of unmanned aerial vehicle, medium and device

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 ...

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 the high measurement cost required to obtain the ground control points, this method cannot meet the positioning requirements of the oblique image of the UAV.
