摘要
本文对建筑物点云分割与提取的方法和流程进行研究.在研究过程中, 通过对建筑物顶面进行分割, 提取出建筑物各顶面的点云, 精确构建建筑物房顶面片, 进而实现建筑物的三维重建.
In this paper, the method and process of segmentation and extraction of building point cloud were studied. In the study, the top surface of the building was extracted by dividing the top surface of the building, and the top surface of the building was accurately constructed, and then the three-dimensional reconstruction of the building was realized.
