Obtain missing keypoints from SMPL model? #64

Closed mnauf closed 2 years ago

mnauf commented 2 years ago

I am interested in obtaining 3D keypoints not provided by surreal, via SMPL model. Let's say top of the head. I have learned that to convert SMPL pose params to 3D keypoints, I will need to convert pose params given in rotation matrices format to axis-angle representation, but will this not only give me keypoints that I already have? It won't provide me with the top of the head.

Once I have the 3D keypoint, I can get 2D keypoint by projecting 3D keypoints onto image.

Please let me know how to figure out extracting missing 3D keypoints from SMPL

Solved. SMPL provides us 6890 vertices. Vertex 335 is the forehead in SMPL
