Camera Calibration Methods for Computer Vision Systems - CCMVS2007
Update: Tentative Schedule available!
Update: Deadline for abstracts extended!
Description of the workshop
Camera calibration is an enabling technology necessary for a wide range of computer vision systems relying on different cues (e.g. 3D data, colour, defocus). This workshop aims at bringing together researchers in computer vision and photogrammetry from universities and industry. Relevant fields are geometrical methods for determining internal and external camera parameters, including non-standard image formation geometries such as those displayed by omnidirectional cameras, fisheye or cylinder lenses, etc. A further area of interest is radiometric calibration as well as calibration of other optical effects such as lens PSF, depth-dependent defocus, vignetting, or chromatic aberration. Of special interest for autonomous computer vision system are methods for automatic consistency checking and adjustment of calibration parameters as well as approaches to self-calibration in structured or unstructured environments.
The specific objectives are:
- Gain a comprehensive overview about the current state of the art in the field of camera calibration, both geometric and radiometric
- Bridge the gap between the domains of computer vision and photogrammetry
- Provide an interdisciplinary forum for the exchange of ideas in the various domains of camera calibration
The workshop programme is based on 10-12 oral presentations and will provide an opportunity for discussions during the presentation session, and posters depending on the number and the quality of contributions.
General topics
- Practical approaches to classical geometrical camera calibration, both internal and external parameters
- Calibration of non-pinhole camera geometries
- Radiometric calibration (absolute radiance and colour)
- Calibration of other lens-specific effects (spatially variable PSF, depth-dependent defocus, vignetting, chromatic aberration)
- Online consistency checking of the aforementioned parameters, optionally including their autonomous adjustment within the vision system
- Self-calibration approaches
- Calibration of active vision systems, including motorised zoom lenses
