Surface Reconstruction and Stereoscopic Video Rendering from Laser Scan Generated Point Cloud Data

Abstract

This paper contains studies about the process of creating three-dimensional objects from point clouds. The main goal of this master thesis was to process a point cloud of the Nidaros Cathedral, mainly as a pilot project to create a standard procedure for future projects with similar goals. The main challenges were two-fold; both processing the data and creating stereoscopic videos presenting it. The approach to solving the problems include the study of earlier work on similar subjects, learning algorithms and tools, and finding the best procedures through trial and error. This resulted in a visually pleasing model of the cathedral, as well a stereoscopic video demonstrating it from all angles. The conclusion of the thesis is a pilot project demonstrating the dierent operations needed to overcome the challenges encountered during the work. The focus have been on presenting the procedures in such a way that they might be used in future projects of similar nature.
