LIS Vectorizer - create vector representations from point clouds

The package contains tools for the delineation of line and polygon vector representations from point cloud data. Applications are the extrusion of shapes and the derivation of skeletons and polygonal 3D shapes from point cloud segments.


Tool: 3D Alpha Shapes from PC Segments

Features
• creation of polygonal shapes from point cloud segments by Tetrahedronisation
• output: 3D polygon shapefile of mesh
Application
• meshing of voluminous objects

Tool: Catenary Curve Fitting

Features
• vectorization of power line cables by catenary curve fitting
• input: classified and segmentized point cloud
• output: 3D line shapefile
• attributes include cable identifier and elasticity parameter alpha
Application
• modelling of power line cables

Tool: Create Pipe Model from Skeleton

Features
• creation of a polygonal pipe model from a skeleton line shapefile
• number of prism faces can be specified
Application
• modelling of volumetric representations from line skeletons, e.g. tree models

Tool: Dijkstra Skeletonizer

Features
• creation of line skeletons from a segmented point cloud with pre-calculated Dikstra distances
• variable node stepping and branching distance
Application
• modelling of linear representations from point cloud segments, e.g. trees

Tool: Extrude Shapes

Features
• extrusion of polygon shapefiles to create 3D block models (LOD1) from outlines with relative height information
Application
• creation of 3D block models (LOD1)

Tool: Extrude Shapes (absolute Z)

Features
• extrusion of polygon shapefiles to create 3D block models (LOD1) from outlines with absolute height information
Application
• creation of 3D block models (LOD1)

Tool: Polygon Outlines from PC Segments

Features
• creation of 3D polygonal shapes (outlines) from point cloud segments
• optional line simplification
• optional polygon rectification to the main directions of the point cloud segment
Application
• outlines of point cloud segments, e.g. building roofs/walls, joint planes
