Unmanned aerial vehicle follow-up carrier landing method and system

Abstract

The invention discloses an unmanned aerial vehicle follow-up carrier landing method and system. According to the invention, the unmanned aerial vehicle is controlled to return according to the GPS positioning information, and when the unmanned aerial vehicle returns to a proper range, the orientation and height of the unmanned aerial vehicle are accurately measured through the local area radio positioning base station arranged at the edge of the landing buffer device; and the unmanned aerial vehicle is accurately controlled to tend to be static relative to the ship deck according to the position and the height, so that accurate landing can be realized. The ship-borne vertical take-off and landing fixed-wing unmanned aerial vehicle can land along with the moving ship, the landing buffer device is used for integrating the local area radio positioning technology, the positioning precision of landing is improved, and the anti-interference capacity of the system is improved. Meanwhile, the problem of damage caused by hard collision between the unmanned aerial vehicle and the ship body during landing can be effectively solved.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles, in particular to a method and system for accompanying an unmanned aerial vehicle to land on a ship. Background technique [0002] Shipborne UAVs are produced to meet the needs of maritime operations and are used to perform tasks such as inspections, surveillance, search and rescue, and intelligence collection in sea areas. [0003] The common landing and recovery methods of carrier-based UAVs include: parachute recovery, net impact recovery, runway recovery, vertical landing recovery, rope hook recovery, etc. Among them, vertical landing recovery is the main recovery method used by ship-borne vertical take-off and landing UAVs. However, when a ship is sailing at sea, affected by various factors such as currents and surges, the horizontal position and heave of the ship are constantly changing, and it is difficult to accurately locate the UAV and the landing platform. Increased the...

Problems solved by technology

However, this landing method based on machine vision guidance requires the integration of additional video acquisition equipment on the UAV, which increases the load weight of the UAV; moreover, the images obtained by the video acquisition equipment are susceptible to interference from the external environment and light; The positioning of visual recognition targets requires a large amount of information to be processed, so this landing method has high requirements for the calculation and control system.

In addition, due to the lack of a landing buffer device in this landing method, it is easy to cause direct collision between the UAV and the hull and cause damage
