Efficient Large-Scale Photometric Reconstruction Using Divide-Conquer And Fusion, Yueming Yang

Legacy Theses & Dissertations (2009 - 2024)

The Structure-from-Motion(SfM) method of constructing a 3D model from 2D images reached maturity in the last decade. However, the computational time of pairwise image feature matching dominates the whole pipeline of SfM, and grows quadratically with the number of images. So the scaling issue is still a challenging problem. This dissertation introduces an efficient framework for large-scale 3D reconstruction from a large set of photos following the SfM paradigm with divide-conquer and fusion. The main novelty is to ensure commonality from overlaps between image sets corresponding to their reconstructed models, which facilitates effective stitching and fusion. Specifically, such commonality is …
