Embodiment Construction

[0013] The operator's head movement indicates that the UAV pan-tilt servo system consists of a head-mounted attitude sensor (1), a ground station (3), a data station (4), (5), an airborne pan-tilt (6), and a video camera (7 ), and video stations (8), (9) form. The ground station (3) calculates the deflection direction and rate of the airborne pan / tilt (6) according to the detection result of the head movement of the operator (2) by the head-mounted attitude sensor (1). According to the airborne cloud platform (6), it can perform pitching and yaw motions under the control of the ground station (3). The camera (7) is installed on the airborne cloud platform (6), and rotates synchronously with the airborne cloud platform (6). Through the video stations (8) and (9), the camera (7) transmits the captured video to the ground station (3) in real time, and displays it in real time.

[0014] Through the real-time image of the camera (7) displayed on the ground station (3), the operat...

Abstract

The invention provides a servo system for instructing a pan-tilt system of an unmanned aerial vehicle (UAV) by adopting head movement of an operator, belonging to the field of UAV control. The servo system is characterized in that the servo system comprises a head attitude sensor, a ground station, data radios, video radios and a UAV pan-tilt system capable of pitching and yawing, wherein the head attitude sensor is used for detecting the head movement of the operator; the ground station is used for computing the deflection command according to the head movement and sending the deflection command to the vehicle-mounted pan-tilt system via the data radios to ensure the vehicle-mounted pan-tilt system and a camera carried by the vehicle-mounted pan-tilt system to deflect towards the direction expected by the operator; the camera returns the shot videos to the ground station via the video radios and the ground station displays the shot videos in real time; and the operator corrects the deflection rate and direction of the vehicle-mounted pan-tilt system in real time according to the videos displayed by the ground station to ensure the camera to aim at the expected target all the time. By using the servo system, the operator can control deflection of the vehicle-mounted pan-tilt system by adopting the gut reaction of own head movement, and the servo system has the characteristics of being easy in operation and convenient use in and can obviously reduce the workload of the UAV operator.

Description

technical field [0001] The invention is a system for controlling the deflection of the unmanned aerial vehicle's airborne platform by using the head movement of the operator, which can conveniently and accurately operate the unmanned aerial vehicle's airborne platform, and at the same time reduce the operating burden on the operator's hands. It is mainly used in technical fields such as aerospace, drones and robots. Background technique [0002] The airborne gimbal of the UAV usually carries a camera for capturing ground images in real time. Therefore, during the flight of the drone, it is necessary to continuously manipulate the deflection of the gimbal to align it with the shooting target. However, the flight of the UAV is highly dangerous and random, so it is difficult to operate the airborne gimbal while operating the UAV flight heavily and nervously. [0003] At present, there are mainly two control methods for drones and airborne gimbals. [0004] Method 1: Two oper...
