[en] Interactivity is one of the key challenges for immersive applications
like gaming. Manufacturers have been working towards interfaces
that are driven by a device (e.g. a Wiimote) or interfaces
that are controlled by a camera with a subsequent computer vision
module. Both approaches have unique advantages, but they do not
permit to localize users in the scene with an appropriate accuracy.
Therefore, we propose to use both a range camera and accurate
range sensors to enable the interpretation of movements.
This paper describes a platform that uses a range camera to
acquire the silhouettes of users, regardless of illumination, and
to improve the pose recovery with range information after some
image processing steps. In addition, to circumvent the difficult
process of calibration required to map range values to physical
distances, we complete the system with several range laser sensors.
These sensors are located in a horizontal plane, and measure
distances up to a few centimeters. We combine all these measurements
to obtain a localization map, used to locate users in the
scene at a negligible computational cost. Our method fills a gap in
3D applications that requires absolute positions.
