What's the pseudocode or algorithm inside solvePnP's SOLVEPNP_ITERATIVE flag?
Recently, For one of my research paper, I need to know pseudocode or algorithm inside solvePnP's SOLVEPNP_ITERATIVE
flag which is based on the Levenberg-Marquardt optimization.
Is there any way to find it? Please help.
Thanks in advance.
It is LM non-linear optimization method with the analytical form of the derivatives of the rotation matrix wrt. exponential coordinates. There are some references in the Rodrigues documentation.
Thanks for your reply. Is it possible to share the link of references?
Have a look at the documentation page: https://docs.opencv.org/
And search for Rodrigues documentation in the calib3d module.
Thanks for your response. I will give a look.
