The Reconstruction Problem

Abstract

Both intrinsic and extr insic parameters are known: we can solv e the reconstruction problem unambiguously by triangulation. Only the intrinsic parameters are known: we can solv e the reconstruction problem but only up to an unkno wn scaling f actor. Neither the extr insic nor the intrinsic parameters are available: we can solv e the reconstruction problem b ut only up to an unkno wn, global projecti ve transformation. Reconstruction by triangulation Assumptions and problem statement Both the extrinsic and intrinsic camera parameters are kno wn. Compute the location of the 3D points from their projections pl and pr
