Problems solved by technology

[0004] There are already patents related to this kind of UAV external positioning system, such as patent CN 209617530 U, but it puts forward higher requirements on the slope and surface friction coefficient of the UAV's four legs and the outside of the positioning system. The way of slotting from the inside of the legs makes the legs of the drone relatively thick and affects the strength of its legs

Abstract

The invention discloses an external positioning system for an unmanned aerial vehicle, which belongs to the technical field of machinery. The UAV external positioning system includes a UAV external positioning device, an all-round mobile platform vehicle, a UAV, and a card position. The present invention solves the problems in related technologies such as difficulty in UAV positioning, large volume, complex structure, difficult control, high cost, and poor adaptability of the UAV external positioning system, as well as the complexity of UAV visual positioning algorithm, high cost, and resistance. The problem of large external interference and other issues, on the basis of reducing the volume, reducing the quality and reducing the cost, the positioning accuracy, anti-interference and compatibility of the external positioning system of the UAV are improved.

Description

technical field [0001] The invention relates to an external positioning system for an unmanned aerial vehicle, which belongs to the technical field of machinery. Background technique [0002] In recent years, UAV technology has developed rapidly. UAVs are widely used in industrial production and daily life due to their advantages of light weight, wide range of uses and convenient use. However, due to the current lack of substantial breakthroughs in drone battery technology, multi-rotor drones generally stay in the air for about 20-30 minutes, which is far from meeting the needs of industrial-grade applications; therefore, prepare multiple batteries to supply a drone It has become the simplest and relatively low-cost method today. Traditionally, the UAV battery is replaced manually. The connection between the UAV and the battery is complicated, the battery replacement is inconvenient, time-consuming, inefficient, and it is impossible to arrange people to be stationed during ...
