摘要
本文提出了一种由未定标图象估计三维射影不变量的新算法．它直接由多幅未定标图象中存在的３Ｄ空间不变量与２Ｄ图象不变量之间的不变关系，通过求解线性方程组的基础解系来估计３Ｄ射影不变量．实验结果表明了本算法的有效性．
A new algorithm for the estimation of 3D projective invariants from uncalibrated images is proposed in this paper. Based on the invariant relationship between 3D space invariants and 2D image invariants in multiple uncalibrated images,it estimates the 3D projective invariants by using the fundamental solution system of linear equations. Finally. experimental results have shown the feasibility of this algorithm.
