Vehicle-mounted landing method and system for unmanned aerial vehicle

Abstract

The invention relates to the field of unmanned aerial vehicles, in particular to a vehicle-mounted landing method and system for an unmanned aerial vehicle. The method comprises the steps: starting avehicle-mounted landing flight mode of the unmanned aerial vehicle; transmitting the speed information and the position information of the vehicle to the unmanned aerial vehicle; enabling the unmannedaerial vehicle to acquire speed information and position information of the vehicle; controlling the unmanned aerial vehicle to fly to a preset height range; combining the speed information and the position information of the vehicle with the position quantity and the speed quantity of the unmanned aerial vehicle and an algorithm updating period to obtain a control quantity, and further converting the control quantity into attitude information to control the flight information of the unmanned aerial vehicle to be matched with the motion information of the vehicle, so that the unmanned aerialvehicle is kept in a moving state, and descends and lands to a target position. The flight information of the unmanned aerial vehicle is controlled to be matched with the vehicle motion information, the flight information of the unmanned aerial vehicle can be well adjusted to be matched with the vehicle motion information, and successful landing of the unmanned aerial vehicle is guaranteed.

Description

【Technical field】 [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a vehicle-mounted landing method and system for an unmanned aerial vehicle. 【Background technique】 [0002] Unmanned aircraft, referred to as "UAV", has been a very active research field in recent years, especially vehicle-mounted drones. Vehicle-mounted drones can The combination of the operating system and the flight control system installed on the UAV enables the UAV to follow the movement of the vehicle, perform tasks such as reconnaissance, surveillance, tracking, aerial photography, etc., and take off and land on a car. It is a complex engineering technology for the UAV to return to the car and land on the car after the mission is over. Before the UAV lands, it first needs accurate positioning. At present, most positioning technologies rely on the GPS navigation system, and the positioning is accurate. The accuracy is extremely low, which can easily lead to positi...

Problems solved by technology

It is a complex engineering technology for the UAV to return to the car and land on the car after the mission is over. Before the UAV lands, it needs precise positioning. At present, most positioning technologies rely on the GPS navigation system, and the positioning is accurate. The stability is extremely low, which can easily lead to positioning failure, and the process of controlling the landing of the UAV is also relatively complicated, which can easily lead to landing failure and affect the execution of the mission.
