摄像机的矩阵具有重要的几何含义,由于对场景进行分析的需要,常常需要把摄像机矩阵的分解内参数矩阵和外参数矩阵的乘积。本文在分析摄像机矩阵的特点的基础上,提出了一种针对摄像机矩阵的快速分解方法.和传统的QR分解相比,本文的方法更加简单而且具有一定的鲁棒性。
Camera matrix has important geometric attributes, for the sage of analysis scene, we need to decompose camera matrix to intrinsic matrix and extrinsic matrix. Based on the properties of camera matrix, a quickly decompose method for camera matrix is proposed in this paper. Compared with QR method our decompose method is simpler and robust.
