摘要

内部参数和外部参数都是已知的,我们可以用三角剖分法明确地解决重建问题。只有内部参数是已知的:我们可以解决重建问题,但只能到一个未知的缩放因子。外在参数和内在参数都是不可用的:我们可以解决重建问题,但只能达到一个未知的全局投影变换。三角剖分重构假设和问题表述相机的外在参数和内在参数都是已知的。根据投影pl和pr计算3D点的位置

The Reconstruction Problem
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
