Title: "MESH OPERATION IN LARGE SCALE LOD MODEL GENERATION"

By

Mr. Sing Yu SIU


Abstract

Fast growing demand for large scale 3D reconstruction is accelerated by the 
popularization of photography drones and cameras in mobile phones for the past 
few years. Capturing of high quality photos has never been made easier and this 
pushes the reconstruction scale to a new level, introducing new challenges to 
the mesh processing techniques.

This thesis proposed a level-of-detail(LOD) mesh generation pipeline that is 
robust and scalable to the ever growing data size. It optimized three major 
mesh operations which are used heavily in the pipeline, fixing challenging mesh 
artifacts, merging meshes without overlapping requirement or generating 
degenerated triangles and adapting a generic mesh simplification algorithm for 
urban scene. Experiment on a large scale data set demonstrated its robustness 
and scalability.
