Fast color correction for rapid scanning in uncontrolled environment

This work addresses the problem of colorizing correctly time-of-flight 3D scans performed during rapid scanning of a site in natural and uncontrolled lighting conditions. Contrarily to the usual approach correcting high resolution pictures, the proposed method combines all available radiometric information to colorize per vertex the medium resolution depth map. The obtained rendering exhibits no visible artifacts, for models composed of a series of scans. Our solution allows to quickly obtain good visual results within a reasonable time, while allowing to consider various other methods to improve colors and rendering.
