computer-vision - Is it possible to compute intrinsic and extrinsic camera parameters from a given camera projection matrix?

Question

If I have a 3x4 camera projection matrix, can I compute all or just some of the individual intrinsic and extrinsic camera parameters, i.e., focal length, principal point coordinates, rotation angles (roll, yaw and tilt), and translation vector? If yes, what are the formula?

Is there any tool in OpenCV/OpenGL/MATLAB that could help me do so?

是的。您继续将投影矩阵分解为上三角矩阵和正交矩阵的乘积。您可以谷歌搜索 RQ-decomposition 以了解详细信息。一个很好的总结在这里。
