We invite contributions on automatic methods for surface reconstruction
from images, multi-view stereo, camera (self-) calibration, motion
estimation and related topics. We encourage submissions of original
scientific work in the subject areas, especially works dedicated to performance
evaluation of methods. A non-exhaustive list of topics of interest is:
Algorithms for Shape-from-X (stereo, motion, silhouettes, shading, focus, ...)
Sensor orientation methods (motion estimation, (self-) calibration, ...) without target-points on the object
Integration of surface reconstruction and sensor orientation methods
Surface representations
Dynamic surface models
Evaluation of reconstruction and orientation methods and surface models:
accuracy and reliability
efficiency and versatility
robustness in automation
performance characteristics
Applications for various remote sensing and close-range sensors
One major aim of the
new Commission III on Photogrammetric
Computer Vision and Image Analysis (led by Wolfgang
Förstner and Helmut Mayer) is to bring together
researchers from the related fields, and to 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 (the organizers of this workshop). The Automatic Calibration and Orientation of Optical Cameras Working Group
deals with any research on image orientation, i.e. camera calibration,
self-calibration, motion estimation, etc. and estimation methods for these tasks. A special goal
is to promote automated methods without requiring targets or signalized
points on the object. The Surface
Reconstruction Working Group considers research on surface modeling from image data.
Besides
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 developed 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 motivations for this workshop are thus threefold: (i) communication
of new scientific results in the related areas, (ii) bringing together
researchers from different communities, and (iii) work towards the
definition of benchmarks.

Paper Submission
All papers will be subject to a double-blind review process which will be carried out by a Program Committee of leading international researchers of the Computer Vision and Photogrammetry areas. Each paper will be reviewed by 3 members of the Program Committee. Based on these reviews, the workshop organizers will decide on acceptance of papers, and presentation mode (oral/poster).
Please observe the
ISPRS guidelines for preparing manuscripts and submit your full
paper in PDF format. The paper length is limited to 6 pages. Make sure that
full rights are set in the PDF document.
PDF generation tools (like Acrobat Destiller) allow to enable or disable certain
activities like printing, copying or editing of the document.
All these rights must be enabled in order to generate the workshop proceedings. Please include page numbering for the reviewing version of the paper, but omit them for the camera-ready version.
The names and affiliations of the authors should not appear in the reviewing version
of the manuscript as it will be directly submitted to the double blind review
process. Please
submit your paper by e-mail and mention the author's names and affiliations in your mail. You will be contacted by e-mail if your paper submission was succesful.
The paper deadline has now passed. Dual submissions with ICCV are still accepted until June 3.
After the review process, you will be requested to process the reviewers'
remarks and to submit your camera ready manuscript before August 26.
Proceedings
Proceedings will be available as CD-Rom.
