基于基本形状及其拓扑关系的点云建筑物重建方法
Reconstruction of building point clouds based on the primitive shape and topology relationship
摘要
Abstract
A comprehensive strategy is proposed to reconstruct a building based on the primitive shape and topological relationship.First,the scene point clouds are segmented using the roughdetail segmentation algorithm based on the normals and the distance between points.The planar clusters are extracted from the segments based on the properties of Gaussian sphere.Second,the walls belonging to the building are recognized and extracted based on the properties such as normal directions and areas.Then,each plane is reconstructed by finding the extreme points after projection.The topological relationships between the planes in the scene are analyzed based on the spatial proximity.The initial reconstructed results are refined based on the topological relationships between planes.The experimental results demonstrate that the building walls can be reconstructed by using our method.关键词
