| 摘 要： | 在对建筑物进行三维实景数据采集时，地面三维激光扫描和无人机倾斜摄影测量是常用的技术手段，通过两种手段获取的数据类型不同，对空间的展示效果及精度也存在差异，特别是在获取建筑物顶部和近地部分的数据各有优劣势，将无人机获取的建筑物顶部数据和地面三维激光扫描获取的近地部分数据进行处理，通过空间多个同名公共点进行转换、匹配，将点云和模型两种数据融合。本文以一个古城门为例进行数据采集，介绍了外业测量和内业处理的方法，并对融合精度进行了分析、探讨。

| Abstract: | In the acquisition of 3D real scene data of buildings, ground 3D laser scanning and UAV tilt measurement are frequently used technical means. The data types obtained by the two means are different, and the display effect and accuracy of space are also different, especially in obtaining the top and near ground data of buildings. This paper studies the processing of the top data of buildings and the near ground 3D laser scanning data are processed, and the point cloud and model data are transformed and matched. The methods of field survey and internal processing are introduced by data acquisition of a ancient gate, and the fusion accuracy is analyzed and discussed. |
