Introduction
Bundler is an open source Structure from Motion software for reconstructing 3D scenarios from unordered image sets. Image sets used in this work have been captured with non-calibrated cameras. In some cases Exif tags are available for focal length initialization (when using digital cameras) and in other cases are not (when using video sequences). Results obtained in this work are aligned to orthoimages. Once alignment is performed, the 3D scenarios are approximately georeferenced.
The aims of the project can be summarized in the following points:

More information about Bundler can be found at Bundler's homepage.
Very nice results of SfM can be seen in Building Rome in a
day.
If you need a software to display PLY files, go to Meshlab homepage.
If you need dense muti-view stereo scenarios from Bundler output files, then have look at PMVS and CMVS.
Acknowledgements
First I would like to thank INTA
for granting me the Rafael Calvo Rodés scholarship, where I started in
the computer vision field, and specially to Severino Fernández, who was
my supervisor during this time. I thank Noah Snavely for kindly
answering the mails I sent him with questions about Bundler and Pablo
Fernandez Alcantarilla for the discussions we had about Bundler's
algorithms and SfM which were very instructive. I also thank the Meshlab team for their
application, which has been essential for displaying and analysing
Bundler's PLY files.
