Title
(EN) DIGITAL IMAGING SYSTEM HAVING DISTRIBUTION CONTROLLED OVER A DISTRIBUTED NETWORK
(FR) SYSTEME D'IMAGERIE NUMERIQUE A DISTRIBUTION REPARTIE SUR UN RESEAU DISTRIBUE
Abstract
(EN)
The three-dimensional imaging system providing distribution over a distributed network. A low-cost convenient three-dimensional imaging system having a digitizer and orientation fixture which automatically acquires and calibrates to each other. Automatic acquisition and calibration provide vastly improved ease of use. The system interfaces with a distributed network, such that authorization for operation and/or access to data captured may be controlled at a remote node on the distributed network.
(FR)
Cette invention concerne un système d'imagerie en trois dimensions à distribution par réseau distribué. Ce système d'imagerie 3D peu coûteux et pratique comporte un numériseur et un dispositif d'orientation à acquisition et étalonnage mutuels automatiques. L'acquisition et l'étalonnage automatiques procurent une amélioration sensible en termes de facilité d'utilisation. Le système fonctionne en interface avec un réseau distribué de sorte que l'autorisation d'exploitation et/ou l'accès à des données capturées peuvent être commandés au niveau d'un noeud éloigné du réseau distribué.
