dim 96 when unnorm 3D keypoints

[andresherrera97]

Hello,
I've been seeing your code and I can't understand why when unnormalizing the 3D keypoint you use an input of dimension 48 and an output of dimension 96. What is the use for the extra dimensions?
Thanks in advance.

96 (96/3=32) is the original data. It contains some extra markers that don't have degrees of freedom; ie, they are located at a constant offset from other markers.
48 (48/3=16) is the number of 3d points we work with.
