Abstract

Procédé et système de projection d'un motif sur une surface réelle comprenant : - un module d'acquisition d'image (201), - un vidéoprojecteur (202), - un processeur (204), - une mémoire (205) comprenant des instructions exécutables par le processeur pour : - acquérir (206a) une image sur laquelle une surface réelle est au moins partiellement visible au moyen dudit module d'acquisition d'image, - déterminer (206b) une transformation géométrique à appliquer audit motif de sorte qu'une fois projeté par un vidéoprojecteur, ledit motif apparaisse en un emplacement prédéfini de la surface réelle, la détermination de la transformation géométrique tenant compte de la position du vidéoprojecteur et de la position de ladite surface réelle obtenue au moyen de ladite image acquise, - appliquer (206c) la transformation géométrique audit motif, - projeter (206d) le motif par le vidéoprojecteur.
