| Summary: | The reconstruction of the 3D geometry of a scene based on image sequences has been a very active field of research for decades.
Nevertheless, there are still existing challenges in particular for homogeneous parts of objects. This paper proposes a solution to
enhance the 3D reconstruction of weakly-textured surfaces by using standard cameras as well as a standard multi-view stereo pipeline.
The underlying idea of the proposed method is based on improving the signal-to-noise ratio in weakly-textured regions while adaptively
amplifying the local contrast to make better use of the limited numerical range in 8-bit images. Based on this premise, multiple shots per
viewpoint are used to suppress statistically uncorrelated noise and enhance low-contrast texture. By only changing the image acquisition
and adding a preprocessing step, a tremendous increase of up to 300% in completeness of the 3D reconstruction is achieved. |
