Building reconstruction from airborne laser scanning data

Abstract

The research on building model reconstruction has been a long-term hot topic in both the photogrammetry and computer vision areas. The airborne laser scanning technique provides new opportunities for building model reconstruction. Despite many investigations on building reconstruction using point clouds, there are still many unresolved problems that need further research, especially fully automatic methods and intelligent user-friendly operations. This article surveys the methods, tools and problems of building model reconstruction using point clouds data. The article also points out some important but unnoticed problems in building reconstruction according to our previous experience. We hope our comments article can be helpful for researchers in understanding their position and for new researcher in acquiring general information. © 2013 Wuhan University.
