摘　　要：为降低三维场景重建的难度和复杂度,提出基于二维地图构建三维虚拟场景的方法。对地图元素的导入、多边形的三角化、地图已有元素的三维构建渲染以及非地图元素的呈现方法进行了详细阐述。所提方法可自动生成三维虚拟场景,避免人工采集环境的复杂度。基于生成的场景可为定位、导航和路径规划等任务提供测试环境,也可为高年级本科生综合实验设计中的仿真、测试或者无人驾驶汽车相关研究机构提供基础平台。In order to reduce the difficulty and complexity of 3D scene reconstruction,this paper proposes a method for constructing 3D virtual scenes based on 2D maps.The import of map elements,triangulation of polygons,3D construction and rendering of existing elements of the map,and the rendering method of non-map elements are elaborated in the paper.The proposed method can automatically generate 3D virtual scenes,avoiding the complexity of manual acquisition of the environment.Based on the generated scenes,it can provide a test environment for tasks such as localization,navigation and path planning,as well as a basic platform for simulation and testing in integrated design for senior university students or for research institutes related to unmanned vehicles.
