Does it look right? – Why capture and reconstruction quality really matter

At first sight, 3D reconstruction can be considered a solved problem. The principles are well understood and we can reconstruct a wide range of objects and scenes using active as well as passive reconstruction approached. However, most of these reconstructions are not convincing when really scrutinized by a human observer. In this talk, I will give an overview over our work on 3D reconstruction with a particular focus on reconstructing thin surfaces. I will then introduce a novel holistic evaluation metric for complete reconstruction and rendering pipelines that focuses on the resulting image quality and tries to take human observations — whether it “looks right” — into account.

Prof. Dr. -Ing. Michael Goesele is head of the Graphics, Capture and Massively Parallel Computing (GCC) at Technische Universität Darmstadt. The main focus of our research interest is the development of digitization methods for all aspects of the real world. This includes capturing geometry, surface color and several other attributes, e.g. reflectance properties of objects. Most of our methods perform the reconstruction solely on photographs that have been taken under controlled conditions (such as constant lighting and known camera parameters). Our latest developments, however, are capable of dealing with photos taken under uncontrolled conditions, for example images from community photo collections such as flickr. Beyond that, we are interested in massively parallel computing to exploit the full potential of nowadays graphics hardware to solve computationally expensive problems in various areas, for example visual computing and bio informatics.
