Robust Photometric Projector Compensation
Anselm Grundhöfer (Disney Research Zurich)
Photometric projector compensation is used in various application ﬁelds, such as building projections and augmented reality. Its preparation, however, is still a laborious process. While several algorithms have been already presented which generate compensated projections with impressive quality, they all require the devices to be, at least partially, radiometrically calibrated and accurately registered to the surface. This process can be cumbersome and time consuming reducing the overall ﬂexibility of the system. Furthermore, it makes the algorithms impractical to deploy, because non-experts might not be able to re-calibrate it accurately and thus the projection quality will be significantly degraded. The main goals of this project are: (1) Development of a compensation algorithm which does not require any radiometrical pre-calibration of the cameras and projectors. (2) Research on how to optimize the compensation images such that it even preserves a high perceptual quality in the case of slight misregistrations.
The developed non-linear color mapping methods are also able to generate high quality results in other applications fields, such as display gamut mapping as well as color space mapping for images and videos
