Hello everyone,

First of all, thank you to the developer community for releasing the sfm module!

In my application, I would like to give an initial guess to the pose (Rotation/Translation) of the different camera. Digging inside the sfm module, I found out the libmv class allows an initial guess for the intrinsic parameters. Is there a way to give an initial guess for the rotation and translation too? I think the overall algorithm is based on an Levenberg-Marquardt minimization that may be sensible to initial value, hence can converge differently if robust initial value are set.

Please let me know if something similar can be done in OpenCV, or if you know some other tools that allow me to initialize a guess value to the transformation.

Thank you,

Silvio
