中文摘要：

针对建筑轮廓、角点等特征在大范围车载和航空LiDAR数据配准中计算量较大、易出现局部最优等情况,利用道路网进行车载和航空LiDAR数据的配准,作为初始配准结果.首先利用LiDAR高程和强度信息提取航空道路,提出基于Hough变换的道路网追踪方法进行恢复;在此基础上,结合车载LiDAR轨迹线数据,利用道路匹配度测度进行道路网配准.

英文摘要：

When building contours and corners are applied for large - scale registration of vehicle and airborne LiDAR, there may be large amount of calculation and local optimum solutions. Road network is used for a rough registration of vehicle and airborne LiDAR data. Firstly, the height and intensity properties are used for roads from airborne LiDAR and a Hough - based road tracing method is proposed to recover complete road network ; on this ba- sis, airborne roads are registered with vehicle trajectories with road matching measures.
