Geometry Acquisition and Processing

Abstract

The exploration of combinations of image based geometry and photometric reconstruction methods in our camera dome is currently in the focus of our 3D acquisition research. But we also use standard laser scanner or shape from stereo techniques to capture 3D models. For the processing of the acquired geometry we develop techniques for automatic repair, completion, compression and post-processing.

Ongoing Projects

3D acquisition devices usually produce unstructured point-clouds as primary output. A challenge in this context is the decomposition of the point-cloud data into known parts in order to introduce abstractions of the originally unorganized data. This information can be used for compression, recognition and reconstruction.

Completed Projects

The european union funded project 3D-COFORM (3D-COllection-FORMation) deals with the development of novel techniques for digitising objects from the cultural heritage area. The goal is to digitise such objects more efficiently and with better quality compared to the current state-of-the-art. This way 3D-documentation will become an everyday practical choice for digital documentation campaigns in the cultural heritage sector.

EPOCH is a network of about a hundred European cultural institutions joining their efforts to improve the quality and effectiveness of the use of Information and Communication Technology for Cultural Heritage. Participants include university departments, research centres, heritage institutions, such as museums or national heritage agencies, and commercial enterprises, together endeavouring to overcome the fragmentation of current research in this field.
