Abstract

The invention relates to an auxiliary positioning method of a drone. The auxiliary positioning method is characterized by including 1), mounting an infrared sensing receiver on a drone; 2), connectingat least four infrared sensing locaters with the infrared sensing receiver mounted on the drone respectively; 3), before flying of the drone, inserting the four infrared sensing locaters into the ground in rectangular arrangement; 4), turning on a GPS device of the drone, and starting up the infrared sensing receiver; 5), on a drone operating system, entering the positions of the four infrared sensing locaters into a GPS system; 6), flying the drone for trail, and by the system, comparing differences between the position of the drone in a matrix, formed by the infrared sensing locaters, and aGPS located position to calibrate a flying coordinate system.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an auxiliary positioning method for unmanned aerial vehicles. Background technique [0002] UAV is a hot carrier for the development of advanced technology in the world today. UAV positioning technology is the basis for UAV route revision. Most of the existing UAVs rely on GPS for positioning, but it has many limitations. The impression of weather, radio, and strong magnetic fields greatly reduces the accuracy of positioning. If it is not modified, it will pose a major hidden danger to the flight safety of the UAV when the UAV is flying beyond the visual range. Therefore be badly in need of a kind of method to solve the above-mentioned difficult problem that people face. Contents of the invention [0003] The present invention aims at the technical problems existing in the prior art and provides an auxiliary positioning method for drones. This method establishes a r...
