摘要
在现有自动驾驶场景仿真软件中构建真实道路模型是对场景开发与验证的必要前提,如何快速及真实地构建是实现场景仿真的关键。该文创新性地采用GIS数据与RoadXML数据格式相结合,使用程序化自动提取道路参数,实现三维道路的真实构建,解决了不借助相关设备情况下获取道路高程信息困难的问题,并通过实车采集GPS数据分析对比和场景仿真工具验证了该方法的合理有效性。
Building a real road model in the existing autonomous driving scene simulation software is a necessary prerequisite for scene development and verification, and how to construct it quickly and realistically is the key to realize scene simulation. This paper innovatively combines GIS data with RoadXML data format, uses the program to automatically extract road parameters, realizes the real construction of 3D roads, solves the problem of difficulty in obtaining road elevation information without the help of related equipment, and by comparison with real vehicle GPS data analysis and scenario simulation tools to verify the effectiveness of the method is reasonable.
