March 2nd - 3rd - 4th: Technical Sessions
Beside the submitted contributions, the event will feature 3 special sessions on:
1- Markerless automated orientation of image sequences - Ref. Fabio Remondino, FBK Trento, Italy
2- Interactive online 3D models - Ref. Sofia Pescarin, CNR ITABC, Italy
3- Procedural modeling for architectures and complex sites - Ref. Christoph Schinko, TU Graz, Austria
Keynote speakers:
- Livio de Luca (MAP-Gamsau CNRS, Marseille, France): A semantic based approach for the digital analysis of architectural heritage
This talk focuses on the fields of architectural documentation and digital representation. It concerns the development of an information system at the scale of architecture, taking into account the relationships that can be established between the representation of buildings (shape, dimension, state of conservation, hypothetical restitution) and heterogeneous information about various fields (such as the technical, the documentary or still the historical one). The proposed approach aims to organize multiple representations (and associated information) around a semantic description model with the goal of defining a system for the multi-field analysis of heritage buildings.
 
- Thomas Kersten (HafenCity University Hamburg, Germany): Beyond automation - Precise and detailled 3D modeling using photogrammetry and terrestrial laser scanning
Full automation in data acquisition and 3D modelling of man-made objects with adequate detail and high-resolution accuracy (+/- 1 cm) for virtual volumetric 3D models is still a dream in photogrammetry and terrestrial laser scanning. There are already promising approaches in the computer vision community and in terrestrial laser scanning for automated data flow, however mostly suffer from richness of detail, completeness and accuracy for the generated product. Therefore automation evaluation procedures can be still found rather rare in object modeling for application in architecture, cultural heritage and archaeology today, where the objects are often very complex and the requirements for a detailed modeling (high level interpretation) are quite high. The talk will present how reliable 3D models with high precision and appropriate details can be achieved nowadays combining automated data acquisition and manual or semi-automated 3D modelling procedures of the acquired data.
 
- Jean-Philippe Pons (CSTB, Sophia-Antipolis, France): High-resolution large-scale multi-view stereo
The talk will present our work on high resolution 3D reconstruction from photographs and its applications to 3D architectural and urban modeling from ground or aerial imagery. Our method leverages computational geometry, combinatorial optimization and GPU computing to handle large-scale scenes, without human intervention, in a few hours of computation time. The accuracy and completeness of the obtained 3D models make our method
an excellent alternative to laser scanning in the architectural modeling pipeline. The talk will describe how this technology has evolved in the recent years from a research prototype to a robust solution offered to public and professional end-users by a leading CAD software company.
