Problems solved by technology

For the automatic landing of UAVs, there are existing automatic landing UAVs based on Global Positioning System (GPS) navigation, but the positioning accuracy of GPS without special processing can only reach 10m, the error is large, and the GPS signal is far away from the obstruction. Many areas, such as dense buildings or forests, will cause increased errors and even signal loss; they may even be interfered by malicious satellite positioning signals and land in the wrong place; professional-grade high-precision GPS equipment is expensive and not economically practicable
The other is a vehicle-mounted drone based on electromagnetic maintenance and automatic positioning, which allows the owner to not have to get out of the vehicle to evaluate the surrounding environment in extreme environments; Severe external electromagnetic interference during tracking and positioning

Embodiment 1

[0048] This embodiment discloses a method for precise landing of a vehicle-mounted UAV, which is applied to a UAV control system. The system includes a UAV 1, a remote control terminal 2 and a parking box 3, such as figure 1 shown.

[0049] An unmanned aerial vehicle 1 includes an electric rotor 4, a fuselage 5, a camera 6 and a flight controller. The camera device is located at the bottom of the fuselage, and is connected to the flight controller through a signal, and the flight controller can transmit photos and video information to the remote control terminal in real time;

[0050]The remote control terminal 2 includes the remote control handle 9 and the UAV flight state control APP10, which controls the flight state and camera function of the UAV, and the sliding cover 7 on the top of the parking box 3 is opened and closed.

[0051] Parking box 3 equipment is positioned at car roof or behind the car, comprises shell, and described shell top is provided with the automatic ...

Embodiment 2

[0084] The purpose of this embodiment is to provide a vehicle-mounted UAV precision landing system.

[0085] A vehicle-mounted unmanned aerial vehicle precision landing system, comprising: unmanned aerial vehicle, remote control terminal and vehicle-mounted apron box with positioning marks on the apron;

[0086] The remote control terminal receives the return command input by the user and sends it to the UAV flight controller, and at the same time sends the current position information of the vehicle; receives the image data sent by the UAV, recognizes the positioning mark on the image, and generates Control commands and send them to the UAV flight controller;

[0087] The unmanned aerial vehicle includes a camera and a flight controller. The flight controller receives the return instruction and the current position information of the vehicle, controls the unmanned aerial vehicle to fly within a certain range of the position, and controls the camera to capture image data inclu...

Abstract

The invention discloses an accurate landing method and system for a vehicle-mounted unmanned aerial vehicle. The method comprises the following steps that a remote control terminal receives a return instruction, sends the return instruction to the unmanned aerial vehicle, and sends current position information of a vehicle; the unmanned aerial vehicle flies to be within a certain range of the position according to the position information, shoots image data containing a parking apron and sends the image data to the remote control terminal; the parking apron is provided with an unmanned aerialvehicle positioning mark; the remote control terminal receives the image data, identifies the positioning mark, and sends a control instruction to the unmanned aerial vehicle according to a positioning mark identification result; and the unmanned aerial vehicle moves or lands according to the control instruction. GPS positioning information is combined with target recognition based on deep learning, so that the landing precision of the unmanned aerial vehicle can be effectively improved.

Description

technical field [0001] The disclosure belongs to the technical field of drone control, and in particular relates to a method and system for precise landing of a vehicle-mounted drone. Background technique [0002] UAV is an unmanned aerial vehicle controlled by radio remote control equipment and its own program control device. Nowadays, UAVs are widely used in many fields such as surveying and mapping, cruising, environmental monitoring, and express delivery. It is of great significance to improve the intelligence, reliability and convenience of UAV applications. [0003] The precise landing of drones is an important factor affecting the application and development of drones in various industries at this stage. For the automatic landing of UAVs, there are existing automatic landing UAVs based on Global Positioning System (GPS) navigation, but the positioning accuracy of GPS without special processing can only reach 10m, the error is large, and the GPS signal is far away fro...
