Design And Realization Of Scene Graph System Of UAV Based On Multigen-Creator/Vega Prime

The paper bases on the existing semi-physical real-time simulation environment for Flight Control System(FCS) of Unmanned Aerical Vehicle(UAV), aims at the actuality of the output in data and curve form the system,based on the sheory of the visualization,uses the technique of the modeling,the system running,the model driving and the data communication,designs and achieves the scene graph system based on Vega Prime real-time simulation system,that could show the real-time flight process of UAV and provides the truth for researching the flight rule of UAV.The paper describes the modeling method by Creator, and constructes the model of UAV, terrain and cabin.By use of the actual flight data of the UAV, we have driven the flight of the three-dimension real mould body in the virtual scene, and we have achieved the scene graph emulation for the flight of the UAV by the alternant function of Vega Prime. The emulation is effective and brings us a actual sense.We have employed the develop environment MFC and Tilcon to develop the interface part of scene graph for the aircraft, also we have designed the button for controlling the virtual scene. The assistant function of the new module for the scene graph perfects the whole scene graph emulation system.Analyzing the three courses that disengage from the Vega Prime environment and the Visual C++6.0 environment, we bring forward the detail resolvent.At last, we put up the half-physics real-time emulation test. We test the functions of the scene graph system for the UAV. Basically, the outcome indicates that the scene graph system for the pilotless UAV the designing demand.
