The Virtual Reality Simulation System Of UAV Flight Attitude And Trajectory

With the continuously development of science and technology, computer softwareand hardware are constantly updated,so the Virtual Reality technology can be widelyused in everyday life.The application of virtual realigy technology used to UnmannedAerial Vehicle simulation system,not only can visually observes the flight attitude of theUAV,can also be used to training manipulator’s manipulation techniques,it has a greatmilitary value and economic value.This thesis takes Unmanned Aerial Vehicle as the study object,develops a UAVflight attitude and flight track virtual reality simulation system with the tool MultigenCreator and Vega Prime and Visual Studio.Net2003.This paper first introduces VirtualReality technology and its development,then put forword a technological route of theUAV flight attitude and flight track virtual realigy simulation system.Then,according tothe characteristics and requirements of the UAV simulation system,designs the UAVflight attitude and flight track virtual reality simulation system.And its basic functionsare as follows:develops a virtual marine ocean environment including wave, UnmannedAerial Vehicle,aircraft carriers and a series of islands,especially introduces the methodof modeling technology of the waves in detail;designs four motion strategies for theUAV,they are MotionGame mode,MotionFly mode,SelfControl mode and Review mode,the user can choose one for UAV’s movement when starting the simulation system, andthe user also can change the motion mode whenever you want;the users can use inputcontrol tools,for examples,keyboard and mouse, to control the UAV to change theflight attitude. In the simulation, designs a Z collision detection method for UAV whenroaming in the virual scene, the UAV will explodes after the collision and has a specialeffect,such as,fire,smoke and so on; Real time display the UAV’s position and attitudeinformation on the status bar and display the flight track under the Selfcontrol motionmode strategy.Finally, according to the technological route and the design ideas,realizes the UAVflight attitude and flight track virtual reality simulation system with the programminglanguage.The system has a well operation result,the virtual scene in the virtual realityscene can give users realistic immersive and the user can control the UAV immedi-ately,the UAV flight attitude and track virtual reality simulation system has a great value and lays a solid foundation for further study.
