基于激光点云数据的室内路网构建方法
摘要
Abstract
In the face of expensive professional-grade 3D laser scanner,an indoor road network construction method based on laser point cloud data was proposed,aiming at the low accuracy or efficiency in the process of building cross-floor road network by using existing 2D base map or manual modeling,and considering how to abstract indoor corridors,corridors and other areas.The method takes the point cloud inside the building collected by the consumer LiDAR scanning equipment as the basic data,combines the through filter and projection filter to preprocess the point cloud,obtains the de-noised planar two-dimensional point cloud,carries out raster binarization processing,and targeted fills the holes in the point cloud,extracts the skeleton line,removes burrs and extracts the skeleton line nodes.The topology relationship between nodes is stored as a graph model in the form of adjacency table,and a 3D road network model can be obtained by using Dijkstra algorithm to find and visualize the shortest path.关键词
