Abstract
An electronic apparatus and method is provided for shape-refinement of a triangular 3D mesh using a modified Shape from Shading (SFS) scheme. The electronic apparatus generates a flat two-dimensional (2D) mesh based on an orthographic projection of an initial three-dimensional (3D) triangular mesh on an image plane that includes a plurality of square grid vertices. The electronic apparatus estimates a final grid depth value for each square grid vertex of the flat 2D mesh based on a modified SFS scheme. The modified SFS scheme corresponds to an objective relationship among a reference grid image intensity value, an initial grid depth value, and a grid albedo value for each square grid vertex of the plurality of square grid vertices. The electronic apparatus estimates a final 3D triangular mesh based on the initial 3D triangular mesh and the estimated final grid depth value.
