Abstract

Des première et seconde séries différenciables d'images sont projetées sur une surface, chaque image présentant un élément source correspondant avec des coordonnées bidimensionnelles connues par rapport au projecteur. Une pose est déterminée à partir de deux caméras espacées placées pour présenter en image au moins une portion de la surface. Les coordonnées tridimensionnelles d'au moins quelques images de la première série sont déterminées avec les caméras, à partir desquelles une pose initiale du projecteur est calculée. Une correspondance est établie entre chacune des quelques images de la première série et un élément source correspondant, à partir duquel on établit la correspondance d'une pose du projecteur améliorée. Les coordonnées tridimensionnelles d'au moins quelques images de la seconde série sont déterminées au moyen de la pose du projecteur améliorée et des caméras, et la surface est caractérisée à partir des coordonnées tridimensionnelles des images des première et seconde séries.
