汽车驾驶训练模拟器视景系统的设计与实现

魏明曹正清龚家伟(,100083):2002-10-07:,;,,,为了解决以往汽车驾驶训练模拟器视景系统图像单一运动不连续真实沉浸感不强等问题,采用先进的视景仿真软件)))OpenGVSSDK和MultiGenCreator,并结合面向对象技术设计与开发了汽车驾驶训练模拟器视景系统该视景系统包括地形地貌模型模块2D物体模型模块3D物体模型模块等技术方面,在单通道图形显示技术的基础上实现了多通道图形显示技术,使得所建立的视景系统既有丰富的场景,又能很好的满足虚拟环境真实沉浸感要求测试结果表明,所建立的汽车驾驶训练模拟器视景系统能够满足汽车驾驶培训的要求视景系统;建模;通道;虚拟环境TP3911007-4333(2003)04-0055-03ADesigningandimplementingofthevisualsystemofautomobiledrivingtrainingsimulatorWeiMing,CaoZhengqing,GongJiawei(CollegeofEngineering,ChinaAgriculturalUniversity,Beijing100083,China)AbstractThevisualsystemofautomobiledrivingtrainingsimulatorandadvancedvisualsimulationsoftware(OpenGVSSDKandMutiGenCreator)weredesignedanddeveloped.Thereareterrainmodel,twoDimensionmodelsandthreeDimensionmodelsinthesystem.Thetechnologyofsingle-channelgraphicsdisplaywasdescribed.Themethodsofmult-ichannelsgraphicsdisplaybasedonsingle-channelwaspresented.Thissystemhasamplesceneandgoodv-isualeffect,andcanbetterfitinwiththeneedofdrivingtraining.Keywordsvisualsystem;modeling;channel;virtualenvironment,,,[1~4],,(Immersion)(Interac-tion)(Imagination)[5],,,,[6],)))OpenGVSSDKMultiGenCreator1111,,,5,12003,8(4):55~57JournalofChinaAgriculturalUniversity1Fig.1Flowchartofmodeling1123000m@3000m,3:1000m@1000m,2000m@2000m3000m@3000m1132D2D3000m@3000m,32D,,1143D3D,3D,BSP(BinarySpacePartitioning),,,,,115,,,:,2D;BSP;LOD,:1),,;2),;3),,,21)22);;2Fig.2Basicresourceandstructureofchanneldisplay(gv_main.c),(gv_user.c),(gv_use_proc.c),(gv_events.c)3)562003(driver_chn),,,fbf11()2()111;,;33Fig.3Structuralrelationshipofmult-ichannelsgraphicsdisplay,,,,,[7]3,,,[1].[D].:,1998[2].[D].:,1998[3].)))[D].:,1998[4].OpenGL[D].:,1998[5],,.()[M].:,1996[6],,,.[J].,2000,12(3):287~290[7].[D].:,2001574:
