结合机载和地面 LiDAR 数据的建筑物重建技术

摘要

机载LiDAR数据虽然能够快速地获取建筑的顶面信息，但是不能够有效地获取建筑物的侧面信息。地面三维激光扫描仪能够有效地获取建筑物的立面信息，但获取建筑的顶面信息较困难。针对机载和地面LiDAR数据在精细建模中存在的问题，采用机载地面LiDAR数据相结合的方式对建筑物进行精细的建模，实验结果表明，采用该法能够实现建筑物的精细建模。%Airborne LiDAR data can quickly access the top surface of the building data, but are not able to obtain the data of the building facade.Terrestrial laser scanners can effectively obtain the data of the building facade.But can not get the top surface of the building data.For the airborne and terrestrial LiDAR data in the meticulous modeling problems, using airborne LiDAR combined with terrestrial data approach to modeling of meticulous buildings, the experimental results show that this method can achieve meticulous building reconstruction.
