Special Session

The FINE Benchmark (Fisheye Indoor Narrow spaces Evaluation)

Many researchers are working with fisheye photogrammetry, low-cost image-based sensors and slam technologies to define reliable approaches to quickly survey indoor and complex spaces. The different approaches become challenging in a narrow environment. A special section will be dedicated to this topic which seems to be of particular interest in the international scientific community linked to the 3D survey of complex architectures, archaeological sites and BIM systems. For this purposes, a benchmark dataset was prepared in order to provide a common playground for the evaluation of the performance of different approaches. Such a benchmark offers the opportunity to tackle one or more topics that influence the final accuracy of the results and to share and challenge your approach over the community. Within the topics that can be studied, we can mention: fisheye distortion models/distortion handling, capturing geometry, pre-calibration, multi-camera constraints, multi-camera synchronization, automated image orientation, point cloud aligment, etc.
The benchmark data were acquired in the Underground tunnels of a castle in the upper part of Bergamo (Italy).

Participants from academia, research institutes and companies are invited to participate to use the benchmark data for research purposes and demonstrate their tools, programmes, processing methods and developments in elaborating image of different types and mobile range-based clouds for the reconstruction of narrow places. Presentations dealing with the benchmark data will be included in a special session of the event - no paper required. All participants will jointly prepare a journal paper after the event.
More technical information about the benchmark are available here.
If you are willing to partecipate to the benchamrk, please contact Fabio Remondino or Francesco Fassi to receive the data. Data must be used only for R&D purposes.
