  1. Urban 3D Models: What‘s underneath? graz university of technology & grintec gmbh Handheld Augmented Reality forUnderground Infrastructure Visualization austria UbiComp 2007, Innsbruck, 16 - 19 September 2007

  2. Geospatial Data + Augmented Reality (AR) = 3D real time visualization of underground infrastructure on handheld devices VIDENTE – RESEARCH PROJECT

  3. Academic Partner VIDENTE – PROJECT PARTNERS Joint Research Project Commercial Partner • Funded by the Austrian Research Promotion Agency (FFG) • BRIDGE scheme, 2nd call • Project duration of 2 years time • Project kick-off in April 2006

  4. AUGMENTED REALITY • Real-time integration of 3D computer graphics into a real world environment (vgl. Azuma 1997) • Computer graphics overlays enhance the real world view visualization of hidden and abstract information • Also known as „Mixed Reality“

  5. Real world view Geodata Camera Tracking Geodatabases Position Orientation HANDHELD AR – HOW DOES IT WORK ?

  6. Real time integration of 3D computer graphics with real world view Highly precise wide-area tracking (position, orientation) Performance ofGraphics Processing Unit Sensor shielding Availability, Run-time Integration with existing systems, SW/HW interfaces Robustness & Outdoor use: Sun light, Temperature, Dust, Wetness, Shock Ergonomics, Weight, Screen size, System interaction HANDHELD AR – REQUIREMENTS WHAT HAS TO BE CONSIDERED? HANDHELD AR SYSTEM

  7. VIDENTE – SYSTEM ARCHITECTURE

  8. VIDENTE – HANDHELD AR SETUP (1)

  9. VIDENTE – HANDHELD AR SETUP (2) SETUP IN ACTION AT INNSBRUCK CONVENTION CENTER

  16. VIDENTE – VISUALIZATION (5) – MAGIC LENS INFORMATION ENHANCEMENT / HIDING

  17. VIDENTE – VISUALIZATION (6) – MAGIC LENS INFORMATION ENHANCEMENT / HIDING

  18. POTENTIALS FOR PRACTICAL USE (1)

  19. Quick and easy locating and self-positioning Interfacing with other systems Spatially intuitive overview of the on-site underground situation Query and presentation of asset related non-geometric information VIDENTE Easy perception of complex underground infrastructure layouts (in particular in urban areas) Quick identification of particular underground infrastructure assets Essential contribution to business process optimization with utilities (intermediate term) Supplement to well established utility network management solutions Maintenance Outage Management Network Information System Mobile Mapping Network Documentation Network Planning Workforce Management Location Based Services POTENTIALS FOR PRACTICAL USE (2)

  20. FIELDS OF APPLICATION WHERE MAY HANDHELD AR COME IN HANDY ? • Visual guidance for digging activities • Utility network planning • Locating hidden utility assets • Locating hidden spots of cable damage • Gas leak detection • On site instruction of technical staff • Visual guidance for technical facilities
