Take-off and landing positioning control method and system for vertical take-off and landing aircraft

Abstract

The invention discloses a take-off and landing positioning control method and system for a vertical take-off and landing aircraft, and relates to the technical field of unmanned aerial vehicle control. The method comprises the following steps: acquiring first positioning information of a target aircraft based on a satellite positioning system; determining a target base station according to the first positioning information, acquiring a real-time signal of the target aircraft based on the target base station, and calculating to obtain second positioning information of the target aircraft; acquiring real-time environment information, and acquiring real-time running state information of the target aircraft; importing the real-time environment information and the real-time operation state information into a preset building digital twin model to determine target positioning information and target aircraft attitude information; and determining a landing position of the target aircraft based on a plurality of laser generators of the take-off and landing platform and a sensor on the target aircraft according to the target positioning information, and completing landing control. According to the invention, the landing position of the aircraft can be accurately positioned, and safe and accurate landing of the aircraft is ensured.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle control, and in particular, to a method and system for taking off and landing positioning control of a vertical take-off and landing aircraft. Background technique [0002] At present, small and micro unmanned aerial vehicles, especially multi-rotor aerial vehicles, have developed rapidly. The automatic control technology of aircraft has been rapidly developed and applied in many fields, such as the automatic flight control of unmanned aerial vehicles, and the automatic driving of manned aircraft. Among them, the landing of aircraft has become a key concern. [0003] The existing aircraft landing control mainly adopts the method of human operation control, the automatic landing method using satellite navigation and positioning, or the method of visual recognition assisted landing, but these existing methods have a large inaccurate positioning and landing position. The pro...
