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 of an unmanned aerial vehicle, and belongs to the technical field of machinery. The external positioning system comprises an unmanned aerial vehicle external positioning device, an omni-directional mobile platform car, an unmanned aerial vehicle and a clamping position. Therefore, problems of difficult positioning of the unmanned aerial vehicle and large size, complex structure, difficult controlling, high cost, and poor adaptability of the external positioning system of an unmanned aerial vehicle in the prior art as well as problems of complex unmanned aerial vehicle visual positioning algorithm, high in cost, large in external interference resistance and the like are solved. The unmanned aerial vehicle positioning precision, anti-interference performance and compatibility of an unmanned aerial vehicle external positioning system are improved on the premise that the size is reduced, the mass is reduced and the cost is reduced.

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 ...
