| 摘 要： | 针对我国高速公路建设发展迅速而信息化管理相对薄弱的现实,论述了车载三维数据采集系统对高速公路沿线设施的空间坐标采集和相关地理信息系统建立的实现过程,即所有设备在工控机控制下,利用GPS授时进行同步工作,采集汽车平台运移过程中道路及两侧地物目标的立体图像、视频图像、三维点云以及瞬时坐标和姿态参数。通过后处理软件,获得道路及其沿线设施的空间坐标,并基于目标的几何特征和相关属性信息,建立高速公路沿线设施空间数据库,最终建立管理信息系统。实验表明,经过原始采集和处理后的空间数据能保证一定的精度,系统的开发基本满足相关部门的需求,具有较高的推广应用价值。

| Abstract: | The article introduces the implementation of data acquisition and relative GIS of express establishment based on vehicle-borne 3D data acquisition system. Namely, the stereo images, video images, 3D point cloud data, instantaneous coordinates and attitude of the roads and the geographical objects along them could be captured during the vehicle running on the control of GPS. Through the post-processing software the spatial coordinates can be figured out, and the spatial database, even the GIS of express establishment were founded based on geometric information and attribute information. The application proved that the processed spatial data had good accuracy. The system and application meets the demand of relative users and is worthy to be popularized widely. |
