Company Name project: URBAN Context project: (IBBT) Project Goal: efficient, large-scale 3D modeling of urban environments, both for digital

cartography as for visualization oriented applications, like care navigation or gaming Goal of using TA 3D maps: turning them into highly compact, structured, and

semantically enriched procedural models Partners using TA 3D maps: EDM, Androme, Procedural and KUL (not yet, but planned) Type TA 3D maps used 3D research topics: structure-from-motion, semantic Level-of-Detail and inpainting,

reverse procedural modeling Components offered by partners: structure-from-motion pipeline already tested on

thousands of km or road and yielding highly precise 3D point clouds using cameras and GPS, CityEngine SW tool for the efficient creation of large-scale city models (e.g. used for Rome Reborne 2.0), portable data capture setup (vision + sound), traffic sign recognition software, façade analysis software (identifying components), efficient compression of image streams, …

Company Description & timing Demonstration Demonstrator 1 – RGB-2-GRB (December 2009)

- Demo 1 will show a largely automated series of steps, running from the raw RGB image data up to 3D measurements for extensive, urban areas.

Demonstrator 2 - Location-based city services (December 2009)- Captured and processed city environment data will be stored at server side from which clients can

request the data they need. Besides navigation in the city, users will be able to go into specific buildings. Additionally, content providers will be provided with facilities for spatial multimedia coupling of for instance text, audio and video. Also, an editor will be created which will allow service providers to add interactive content to the virtual world.

Potential business case: - 3D navigation system data capture, strong automation thereof - low-cost production of movie and game environments - shifting digital cartography from in the field to in the office measurement - infrastructural planning - real estate business
