    abstract     = "The development of hardware and software is accelerating. Web cameras have become common and cheap, algorithms in image analysis are getting more advanced, and computer s processing power has increased so that more advanced image analyses can run real-time.

These advances open new possibilities of interaction via web cameras, and are the foundation for a concept which is proposed and implemented in this thesis. 

The concept is based on real-time computer graphics, anaglyph stereoscopics, image analysis object tracking, {2D} to {3D} reconstruction, camera calibration and off-the-shelf hardware in form of webcams and a desktop computer.

It is shown through the implementation that it is possible, with these components, to build the system on a desktop computer setup for the cost of two off-the-shelf webcams.

The implementation can produce a view dependent {2D} stereo projection of the {3D-}data onto the screen enabling true moving parallax using viewer tracking. It is possible to interact with the {3D-}data (E.g. moving, rotating, editing or drawing coarse sketches in {3D}.) in an intuitive way using a tracked pointing device.

In Danish:

Udviklingen inden for hardware og software er accelererende. Web-kamera er blevet almindelige og billige, algoritmer inden for billedanalyse bliver mere avancerede og computere er blevet s{\aa} kraftfulde, at mere avancerede billedanalyse algoritmer kan k{\o}re i realtid.

Denne udvikling {\aa}bner op for nye muligheder indenfor interaktion vha. web-kamera og er grundlaget for konceptet, som foresl{\aa}s og implementeres i dette thesis. 

Konceptet er baseret p{\aa} realtids computer grafik, anaglyph stereoskopi, objekt detektion vha. billede analyse, {2D} til {3D} rekonstruktion, kamera kalibrering og standard hardware i form af almindelige web-kameraer og en personlig computer. 

Gennem implementeringen er det vist at det med disse elementer er muligt at bygge systemet p{\aa} en personlig computer for prisen af to web-kameraer. Implementeringen kan skabe en synspunktsafh{\ae}ngig {2D} stereo projektion af {3D-}data p{\aa} sk{\ae}rmen med korrekt bev{\ae}gelses parallakse, idet brugeren f{\o}lges optisk. Det er muligt at interagere med disse {3D-}data (fx flytte, rotere, editere eller tegne grove skitser i {3D}) p{\aa} en intuitiv m{\aa}de vha. et pegeredskab, som systemet f{\o}lger optisk."
