Subject

The student is given an algorithm for the automatic depth reconstruction from images shot by a normal commercial camera.

The aim is to integrate all individual depth reconstructions in an integrated 3D model.

This is achieved by automating the processing pipeline of images into two open-source software packages: Bundler and PMVS2

Bundler is a structure-from-motion (SfM) system for unordered image collections.

PMVS2 is a multi-view stereo software that takes a set of images and camera parameters, then reconstructs 3D structure of an object or a scene visible in the images.

The reconstructed 3D models are displayed in a third open-source application, Meshlab.

The main task of this thesis work was to automate this processing chain, such that no user intervention is required (unordened images go in => dense 3D model comes out)

Remaining Issues: Due to limitations of the RAM memory (2GB), it is not possible to process large sequences at high resolutions.
