Augmented reality basically
consists of superimposing digital information onto a representation of
the real world. Most of the time, this superimposition is only visual,
e.g. synthetic images are added onto images on the real world. In this
talk, we will present the various application domains of augmented
reality before focusing on the scientific challenges it has to address.
Integration of the real and the virtual world include several
- The famous geometric one
is called pose camera computation where the position and orientation of
a camera must be computed with respect to the virtual world in order to
be able to project additional content. It can make use of synthetic
markers as well as more natural features extracted from the images
- The second one is the visual
registration between both worlds, i.e. the influence of each world on
the other (occlusions, shadows caused by either virtual or real
objects, lighting consistency...).
At last, we will present some of our
recent works in the field of augmented reality. We will more specifically
present our recent works about augmented maps, as an ongoing
collaboration between Keio University HVRL lab and our group. Augmented
maps make use of standard unprepared paper maps on which digital
content can be reprojected after the map has
been recognized and registered with GIS (Geographical Information
System). To this end, we first detected road intersections and use
their spatial distribution to recognize and locate the map.
Prof. Guillaume Moreau obtained his PhD
in computer science in 1998 from Rennes University. After a fi
rst position at Ecole
des mines de Paris, he moved as Associate Professor to Ecole Centrale de Nantes
in 2002, where he became full Professor in 2011. His research activity takes
place at the CERMA laboratory which studies the "atmospheres"
of architectural and urban environments. He is currently head of the computer
science team of the lab. His research covers various activities in the
elds of virtual reality, from the integration
of autonomous human beings to human perception in virtual environments
(at the psychophysics, functional or sensitive level). He currently
studies the link between digital images and information systems through
virtual environments and augmented reality.
