CA 2668430

Capturing a surface in motion picture, including: covering a surface with a pattern formed of a marking material; acquiring a sequence of image frames, each image frame of the sequence including a plurality of images of the pattern covering the surface; deriving a mesh object from the plurality of images for the each image frame; tracking the mesh object in each frame through the sequence of frames; and generating animation data modeling a characteristic of the surface using the tracked mesh object.

L'invention porte sur la capture d'une surface dans une image animée consistant à: recouvrir la surface d'un motif formé d'un matériau de marquage; acquérir une suite d'images dont chacune comporte plusieurs images dudit motif couvrant la surface; tirer de la suite d'images un objet maillé pour chaque image; faire le suivi de l'objet maillé dans la sutie d'images et produire des données d'animation modélisant une caractéristique de la surface en utilisant l'objet maillé suivi.
