Creating a Polygonal Model of Osnabrück Castle

Zusammenfassung (Abstract) :

State-of-the-art 3D laser scanners allow historic sites to be scanned at high resolution and accuracy. They may be used on mobile platforms to scan large areas from different viewpoints. Using state-of-the-art mapping and localization methods [3], single point clouds can be automatically registered, resulting in consistent high-resolution 3D point clouds of the scanned scene. However, the sheer volume of collected data is difficult to handle. Even rendering all points for visualization might be impossible, since such point clouds may contain billions of points. To reduce this overhead whilst preserving geometric accuracy, a common approach is to generate triangle meshes representing the scanned surfaces.
