Hello Swook, Thank you very much for sharing your excellent work. I am confused about the transformation between the rotation matrix and Euler angles. When you transform the rotation matrix to Euler angles, as for the pitch component, it should be np.arcsin(-head_mat[1, 2]). However, I found the sign is missing in the code. Can I ask why the negative sign can be ignored?

Thank you for your answer in advance.
