Hello, thank you for providing such a good gaze estimation dataset, it is really a great job!
I have a few questions to ask:
1. What do the parameters pix2mm, screen_translation, and screen_rotation in mirror_position.xml mean, and how are they obtained? How to ensure the measurement accuracy?
2. How are the coordinate points in the screen coordinate system converted to the camera coordinate system? Do you use the matrix in mirror_position.xml? Can you provide code to show this calculation process?
3. How do you get the cam_translation and cam_rotation in the calibration parameters(camxx.xml) of different cameras? Are you using a ruler to measure the distance between different cameras? How to ensure the measurement accuracy?
4. How are the parameters in the face_model.txt file calculated? How to ensure accuracy?
