摘　　要：虚拟汽车测试试验场是智能汽车虚拟测试的基础,它的研究和创建对智能汽车虚拟仿真测试具有重要意义。文中以长安大学渭水校区汽车测试试验场的数字化虚拟漫游的研究为主要内容,利用3Dmax建模软件和游戏引擎工具Unity3D,开发出了一套虚拟汽车试验场漫游系统仿真软件。该系统采用多场景建模方法,构建虚拟汽车测试试验场的三维场景,如模拟汽车测试试验场的高速环道、坡道、弯道、龙门架、交叉口、S弯等真实场景,并结合驾驶模拟器以第一人称视觉进行虚拟汽车试验场的漫游,驾驶员可直接控制虚拟场景里的车辆行驶,增强人机交互的体验。通过漫游效果可知,该系统为智能汽车的虚拟仿真测试提供了高逼真度的真实测试环境,简化了室外汽车道路测试的步骤,大大地节约了测试成本,对智能汽车性能的测试提供了一种新的测试途径。Virtual vehicle test field is the basis of virtual testing for intelligent vehicle,and its research and creation is of great significance to the virtual simulation test of intelligent vehicle.Based on the research of digital virtual roaming in the automobile test field of Weishui campus of Chang’an University,we use the 3Dmax modeling software and game engine tool Unity3D to develop a set of virtual vehicle test field roaming system simulation software.The system uses multiple scene modeling method to construct the 3D scene of virtual automobile test field like simulating the real scene of high speed ring road,ramp,bend,portal frame,intersection,S bend and so on.Combined with the driving simulator to conduct the virtual vehicle test field tour with first-person vision,the driver can directly control the vehicle driving in the virtual scene and enhance the human-computer interaction experience.Through the roaming effect,the system provides a real test environment with high fidelity for the virtual simulation test of the intelligent vehicle,simplifies the steps of the vehicle road test,and greatly saves the test cost,which gives a new test way for the test of intelligent vehicle performance.
