CA 2760006

A point cloud assisted photogram-metric restitution method is described. Said method comprises: the simultaneous visualization on a screen (5) of the ensemble of a stereoscopic image (33) and a point cloud (34) acquired on a given area (2), said stereoscopic image deriving from at least a couple of photogrammetric images (11) acquired on said given area (2) and oriented according to the same coordinate system of the point cloud, the real time connection of the colli-mation mark (S) of the stereoscopic image with the corresponding collimation mark (S') of the point cloud.

L'invention porte sur un procédé de restitution photogrammétrique assisté par nuage de points. Ledit procédé comprend : la visualisation simultanée sur un écran (5) d'un ensemble formé d'une image stéréoscopique (33) et d'un nuage de points (34) acquis sur une zone donnée (2). L'image stéréoscopique est issue d'au moins un couple d'images photogrammétriques (11) acquises sur ladite zone donnée (2) et orientées selon le même système de coordonnées du nuage de points et la connexion en temps réel du repère de collimation (S) de l'image stéréoscopique avec le repère de collimation correspondant (S') du point de nuage.
