Abstract
A method for generating information regarding a 3D object from at least one 2D projection thereof, the method comprising providing at least one 2D projection of a 3D object, generating an array of numbers described by: EQU .alpha..sub.ijk =v.sub.i 'b.sub.jk -v.sub.j "a.sub.ik (i,j,k=1,2,3), PA1 where a.sub.ij and b.sub.jk are elements of matrices A and B respectively and v.sub.i ' and v.sub.i " are elements of vectors v' and v" respectively, wherein the matrices and vectors together describe camera parameters of three views of the 3D object and employing the array to generate information regarding the 3D object.
