Abstract (en)

[origin: WO9634365A1] A method for generating information regarding a 3D object from at least one 2D projection thereof. The method includes providing at least one 2D projection (40) of a 3D object, generating an array of numbers (50, 60) described by: aijk = vi'bik - vj''ajk (i,j,k = 1,2,3), where ajk and bjk are elements of matrices A and B respectively and vi' and vi'' are elements of vectors v' and v'' respectively, wherein the matrices (50) and vectors (60) together describe camera parameters of three views (102) of the 3D object and employing the array to generate information regarding the 3D object (70).
