Camera Intrinsic for projecting the mesh and the landmarks #25

Hi,

I hope you are doing well. I wanted to ask, what is the camera intrinsic that you consider while projecting the mesh and landmarks back to the 2D image?

This work and other work using 300W-LP for training didn’t get exact metric scale, and all the units are in pixels including the gt landmarks. Projecting 3D to 2D simply take the first two components.

You can align scale to meters by some prior(like outer interocular distance) or do scaled-ICP
