Title: METHOD AND DEVICE FOR DETERMINING A 3D MODEL
Abstract:
Embodiments relate to a method for determining a 3D model of a surface (S), executed by a 3D model determination device (4), comprising: - obtaining (S1 ) a plurality of 2D+Z images of said surface (S) from respective 2D+Z image sources (3), - determining (S2), in function of the 2D+Z images, implicit surface data (sdf+) modeling said surface (S), wherein the implicit surface data (sdf+) specify, for respective points (p^ of a 3D field, a distance (d) between said point and said surface and a 2D+Z image source identifier (C0, C1, C2) associated with said point, - determining (S3) a plurality of vertices (V;) in function of the implicit surface data, - for at least one of said vertices, determining (S4) at least one 2D+Z image source associated with said vertex in function of the implicit surface data, and at least one texture identifier (T,ID) and 2D texture coordinates (vi) associated with said vertex in function of 2D+Z image source modeling data associated with the determined at least one 2D+Z image source.
