Question Regarding the Reference for Calculating Euler Angles #1

Thank you for sharing such an impressive project! I have a question about the calculation of Euler angles from 2D keypoints in the projected image, specifically in the function „calculate_euler_angles“ within the script „head_model.py“. Despite reviewing several well-known papers and books related to computer vision, I couldn't find a clear reference for these equations. Could you recall why the Euler angles can be recovered using this method, or kindly provide the reference for them? Looking forward to your reply.

Thank you for your interest. This is highly related to my previous work An Intuitive and Unconstrained 2D Cube Representation for Simultaneous Head Detection and Pose Estimation. Please refer the 2.1 2D Cube Representation part in the paper for more details.
