欧式聚类可以提取平面吗，欧式聚类用来干什么啊

Question

今天实习带我的职工，让我用欧式聚类提取圆柱体，线、和面，确定不是别的吗

Answer 1

pcl有欧式聚类的函数：

Euclidean Cluster Extraction — Point Cloud Library 0.0 documentation https://pcl.readthedocs.io/projects/tutorials/en/latest/cluster_extraction.html?highlight=cluster

不过拟合圆柱体、线、面应该使用RANSAC，pcl也有相应的函数:

Cylinder model segmentation — Point Cloud Library 0.0 documentation https://pcl.readthedocs.io/projects/tutorials/en/latest/cylinder_segmentation.html?highlight=cylinder

Plane model segmentation — Point Cloud Library 0.0 documentation https://pcl.readthedocs.io/projects/tutorials/en/latest/planar_segmentation.html?highlight=plane

另外dbscan可以做聚类，将点云分成不同的块，open3d有现成的example:
