基于移动测量技术的车道级道路电子地图制作

Mapping for Lane-level Digital Maps Based on Mobile Mapping System

高精度车道级道路电子地图是实现车道级导航与监控的基础地理信息数据和必要条件,未来在无人驾驶汽车方面具有广阔的应用空间。据此,研究了车道级道路电子地图的制作,实现了路径为通过高精度、高分辨率道路得到的航空影像,结合具有三维激光扫描和全景数据采集功能的移动测量车采集相关道路数据,提取了满足亚米级的导航与监控要求的道路路网数据,包括车道数、车道宽等属性数据等,按照导航电子地图的要求制作了高精度的道路电子地图。

Lane-level navigation will be widely applied in unmanned ground vehicle which requires high precision lancqevel digital maps for its basic geographic information data. By this, a method of making lain〉level digital maps with high precision and high resolution aerial photos of road is put forward. Coupled with three dimensional laser scan data and panorama data, road network data which meet sub-meter navigation and monitoring requirements is extracted, including the number of hmes. lane width and other attribute data.
