Embodiment 1

[0043] This embodiment provides a visual control system. The development of the visual control system of the present embodiment is based on the OSG (OpenScene Graph) open source application program interface, using VS2010, QT5.

[0044] figure 1 It is a block diagram of the relationship between the modules of the visual control system, such as figure 1 As shown, the visual control system of this embodiment is composed of a control input module, a communication module, a data processing module, and a control display module. The control input module provides the observer with the function of quickly inputting control commands on the programmable touch keyboard. The communication module provides a unified transceiver interface for each functional module of the visual control system. The data processing module completes the parsing and updating of the received data. The control and display module responds to the update data of the data processing module in real time, and reali...

Embodiment 2

[0055] To observe the three-dimensional physical laws of the drone, it is necessary to display the position (longitude, latitude, height) and attitude data (pitch angle, yaw angle, roll angle) of the drone at different times, and want to flexibly adjust the viewing angle position and observation attitude, the observer also needs to be able to flexibly adjust its longitude, latitude, altitude, pitch angle, yaw angle, and roll angle. Radius visibility control analysis, visibility control analysis between two points, superimposed two-dimensional sub-window display part analysis. In the software working thread, the frame cycle updates the position data of the drone, and the scene moving body is driven in real time through the 3D engine. In each frame of the scene, the drone's longitude, latitude, height, and pitch are updated once. Use these values ​​to set the position of the 3D solid model of the UAV, and draw the scene environment at the new position, so as to realize the relat...

Abstract

The invention belongs to the field of virtual scene control, and solves the problem that a scene without a mouse and a keyboard cannot be flexibly controlled in real time. The visual control system based on the unmanned aerial vehicle ground station comprises a control input module, a communication module, a data processing module and a control display module. A plurality of shortcut function keysare defined and arranged on a programmable touch keyboard; a control analysis function domain is interviewed between two points of a control input module through one or more combinations of a plurality of shortcut function keys, a control instruction is input through a central point and radius interview control analysis function domain and a two-dimensional sub-window display function domain, andrelative motion state analysis between an observation point and an unmanned aerial vehicle is achieved; the unmanned aerial vehicle is taken as the center, and the flight state analysis of the unmanned aerial vehicle is observed from different directions in cooperation with different radiuses; and instrument parameters and operation states of the unmanned aerial vehicle are selectively displayed.According to the invention, the overall use experience of the visual scene can be obviously improved, and the repeated research and development cost of visual scene control is reduced.

Description

technical field [0001] The invention belongs to unmanned aerial vehicle control technology, in particular to a visual control system based on an unmanned aerial vehicle ground station. Background technique [0002] In the UAV general ground control station, the multi-dimensional observation of the UAV's flying attitude and the relative position of the UAV and the airport can allow the UAV pilot to grasp the flight status of the UAV more vividly and intuitively as a whole. Facilitate timely judgment and decision-making. With the continuous development of virtual simulation visualization technology, research on visual control has been going on. [0003] According to different control methods, there are several common control methods: such as mouse and keyboard direct control method, directly use the left and right mouse buttons, scroll wheel and keyboard combination keys to input control; visual page control method, directly design the commands that need to be controlled to t...
