Align the coordinates of 3D landmarks

Open ivanlen opened this issue 5 years ago • 3 comments

Hey congrats for this beautiful job, very interesting actually.

I was wondering if there is way to

  1. get a 3d representation of the landmaks, like (x,y,z) coordinates for each landmark point.
  2. I would like to align the arrays of landmarks of different faces with a reference landmarks.

Ideally I would like to have all the 3d landmarks coordinates aligned to the same reference point, for example: all the landmarks coordinates are the coordinates of a frontal face where the proportions of the face are all similar.

I am a little confused about your question.

  1. Each landmark has a (x, y, z) coordinates, by weak perspective projection.
  2. Just applying the ICP ?

Hi, I wonder if the world coordinates of landmarks should be "self.bfm.u_base + self.bfm.w_shp_base @ alpha_shp + self.bfm.w_exp_base @ alpha_exp" in TDDFA.recon_vers()?

Hello! I have some question about the z axis. I'd like to know does the Z coordinate represent the depth information of the landmarks? Looking forward to your reply!
