Abstract

The invention discloses an unmanned plane three-dimensional flight track precision detection method and system. The method comprises the steps of acquiring the three-dimensional flight track of an unmanned plane in real time by an airborne differential GPS unit arranged in the unmanned plane to obtain a preset three-dimensional flight track of the unmanned plane; measuring the distances between at least three detection radars of a radar detection unit and the unmanned plane in real time to obtain at least three distance data; calculating the actual three-dimensional flight track of the unmanned plane based on the at least three distance data; and calculating accurate assessment parameters for the three-dimensional flight track of the unmanned plane based on the preset three-dimensional flight track and the actual three-dimensional flight track. According to the technical scheme of the invention, the unmanned plane can be three-dimensionally positioned by the extra arrangement of the detection radars, so that the actual flight track of the unmanned plane can be positioned at a high precision. Meanwhile, through comparing the three-dimensional flight track of the unmanned plane detected by the differential GPS unit with the actual three-dimensional flight track of the unmanned plane, the accurate three-dimensional flight track precision of the unmanned plane can be obtained. Therefore, the actual flight track of the unmanned plane can be positioned at a high precision.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a method and system for detecting the accuracy of a three-dimensional flight track of an unmanned aerial vehicle. Background technique [0002] With the rapid development of the application of UAVs in the field of electric power inspection, the traditional working mode of using manual on-site inspection of transmission lines is slowly changing. The traditional manual inspection method takes a long time, has high labor costs, and is difficult, and it is easy to affect the personal safety of inspection personnel in special environments. UAV inspections can not only improve the efficiency of inspection operations and save costs, but also record the characteristics of transmission lines, the environment of transmission lines, and the trajectory of UAV inspections in different forms (including video, visible light / infrared images, etc.) efficient storage....
