METHOD FOR THE THREE-DIMENSIONAL DIGITISATION OF A SURFACE, COMPRISING THE PROJECTION OF A COMBINED PATTERN

The invention relates to the use of a structured pattern in the construction of a three-dimensional digital model of a physical surface (2), in which the pattern is projected onto the surface (2), said pattern being formed by combining a primary pattern (28) comprising an array of spaced-apart conti...

Beschreibung
Zusammenfassung:	The invention relates to the use of a structured pattern in the construction of a three-dimensional digital model of a physical surface (2), in which the pattern is projected onto the surface (2), said pattern being formed by combining a primary pattern (28) comprising an array of spaced-apart continuous straight fringes (29) and a secondary anisotropic pattern (30) extending through the spaces between the fringes (29). Utilisation d'un motif structuré dans la construction d'un modèle numérique tridimensionnel d'une surface (2) physique, dans laquelle le motif est projeté sur la surface (2), dans laquelle le motif est formé par la combinaison d'un motif primaire (28) comprenant un réseau de franges (29) rectilignes continues espacées, et d'un motif secondaire (30) anisotrope s'étendant dans les espaces entre franges (29).
