Generation of 3d City Models from Airborne Laser Scanning Data
Airborne laser scanners enable the geometric acquisition of the terrain surface, including objects like trees or buildings which rise from the terrain. Even though for a number of applications a so{called Digital Surface Model (DSM) representing the surface geometry by an object independent distribution of points is su cient, the further quali cation of the original scanner data is necessary fo...
متن کاملIntelligent Laser Scanning of 3D Surfaces Using Optical Camera Data
aBstract In CAD/CAM, reverse engineering involves obtaining a CAD model from an object that already exists. An exact replica can then be produced, or modifications can be made before manufacture. Single-perspective triangulation sensors provide an inexpensive method for data acquisition. However, such sensors are subject to localised distortions caused by secondary reflections or occlusion of t...
متن کامل3D Modeling Study Using 3D Laser Scanning Data Based on Xuzhou Turtle Mountain Han Tomb
Using three-dimensional laser scanner system to measure the Turtle Mountain Han tomb and obtained the point cloud. To the noise points and large holes on the surface, this paper first present an approach that based on the basic principle of least-squares to eliminate the noise points. Then on the basis that there is certain continuity between the holes and their surrounding surface, an approach...
متن کاملLaser Scanning: 3D Analysis of Biological Surfaces
This chapter introduces laser scanning to students and researchers who are interested in using this three-dimensional (3D) acquisition method for biological research. Laser scanning is yet another tool for transforming biological structures into 3D models that contain useful geometric and topological information. Current laser scanning technology makes it relatively straightforward to acquire 3...
متن کاملInfluences of Surface Parameters on Laser 3d Scanning
The quality of 3D scanned data is influenced by many factors, such as scanned surface color, glossiness, geometry, ambient light, scanner resolution, proper selection of scanned segments, etc. Surface color and glossiness are important sources of errors, and this paper studies their effects on a specific commercial scanner. Preparatory phase of digitizing process includes selecting proper combi...
