decomposeProjectionMatrix 是OpenCV 中用于分解投影矩阵的函数。投影矩阵通常用于计算机视觉中的相机标定和三维重建任务,它包含了相机的内参矩阵、外参矩阵以及可能的透视变换参数。decomposeProjectionMatrix 的作用是将这些参数从投影矩阵中分解出来,以便于后续的处理和分析。

When using decomposeProjectionMatrix(), the returned rotation matrix is not consistent for different scales of input matrix P. Specifically, for small scales of the matrix P, the rotation matrix returned has significant error and does not fulfill the expected orthonormal conditions (i.e. orthogonalit...
