CA 2484586

A simulator (1) has a body form apparatus (2) with a skin-like panel (4) through which laproscopic instruments (5) are inserted. Cameras (10) capture video images of internal movement of the instruments (5) and a computer (6) processes them. 3D positional data is generated using stereo triangulation and is linked with the associated video images. A graphics engine (60) uses the 3D data to generate graphical representations of internal scenes. A blending function (70) blends real and recorded images, or real and simulated images to allow demonstration of effects such as internal bleeding or suturing.

La présente invention a trait à un simulateur (1) comportant un appareil présentant la forme d'un corps (2) comportant un panneau ayant l'aspect de peau (4) à travers lequel des instruments de chirurgie laproscopique (5) sont introduits. Des caméras (10) captent des images vidéo du mouvement interne des instruments (5) et un ordinateur (5) en effectue le traitement. Une donnée de position tridimensionnelle est générée au moyen d'une triangulation stéréo et est combinée avec les images vidéo associées. Un moteur de graphique (60) utilise la donnée tridimensionnelle pour la génération de représentations graphiques des scènes internes. Une fonction de mixage (70) effectue le mixage des images réelles et enregistrées, ou d'images réelles et simulées en vue de permettre la démonstration des effets tels que le saignement ou les sutures internes.
