google::ceres in openCV for rolling shutter PnP

edit

Hi guys,

I've implemented yet another extension to solvePnP to solve for rolling shutter images and I'd love to share it. However, I actually used ceres for the optimization and autodif. It'd possible to remove the autodif and calculate the jacobian by hand but it might still be a bit tricky to implement Levenberg-Marquardt on my cost function.

so...

How do you see an optional third-party library like ceres being used inside openCV?

Cheers, Henrique
