Pytorch rotation matrix

WebThere are many ways to represent rotations including Euler angles, rotation matrices, axis-angle vectors, and unit quaternions. In deep learning applications, it is common to use unit quaternions for their simple geometric and algebraic structure.

WebI was wondering the reasoning behind this change. As far as I know, batch_rodrigues method was being used in FLAME to compute rotation matrix. I also see that full_pose has 30 elements instead of 15. I have a project which uses a FLAME version that uses batch_rodrigues, I am unable to use it due to this change.

WebSep 27, 2024 · The orthonormal matrices form two connected sets: the rotations (determinant =1) and the rotations with reflection (determinant=-1). If you have a learning rate that isn't too high, your transformation won't be able to jump between these components, so if you start your weights off at rotation they'll stay a rotation.
