WebTriangulation is a deceptively simple concept, simply involving the pairwise intersection of 3D lines and planes. Practically, however, one must carefully calibrate the various cameras and projectors so the equations of these geometric primitives can be … WebHowever, Taubin's method utilizes only the point geometry, and not the tangent space. And I am not aware of many methods, which are suitable for fitting quadrics such that the tangents of the quadric also match the tangents of underlying point cloud. I am looking for potential extensions of the method above, or any other to cover these first ...
