The workshop Towards Benchmarking Automated Calibration, Orientation and Surface Reconstruction from
Images (BenCOS) of the International Society for Photogrammetry and Remote Sensing (ISPRS) focuses on
automatic methods for surface reconstruction from images, multi-view stereo, camera (self-) calibration, motion
estimation and related topics.

One major aim of the new Commission III on Photogrammetric Computer Vision and Image Analysis is to bring
together researchers from the related fields, and let them benefit from mutual experience. The Working Groups
Automatic Calibration and Orientation of Optical Cameras and Surface Reconstruction are co-chaired by
researchers from the Computer Vision and Photogrammetry communities.

Apart from being a forum for discussing new scientific results, the major goal of these Working Groups is to
establish true benchmarks for the performance evaluation of proposed methods. We believe this is a highly
important aspect of scientific research; it allows an objective comparison of different approaches, catalyzes
new developments, and eases the access of potential commercial users to these research areas and
communities. The motivation for this workshop is thus threefold:

- communication of new scientific results in the related areas,
- bringing together researchers from different communities, and
- working towards the definition of benchmarks.

The workshop proceedings include the ten presented papers. Reviewing was carried out in a double-blind
process by leading international researchers of the Computer Vision and Photogrammetry areas. Each full
paper has been reviewed by 3 members of the Program Committee.

We hope that all workshop participants will leave Beijing with the most rewarding memories in the scientific,
technical and social aspects, and that those unable to attend will find the proceedings a valuable source of
information.
