Can I ask you the intrinsic parameters of camera in the DIRL Gaze Dataset ? #4

Hi, I want to use the DIRL Gaze Dataset to do some experiment, but I can't find the camera parameter. Can you share it, please? Thanks.

Hello, what kind of camera parameters you want to know? For your information, we didn't perform the camera calibration to obtain the exact intrinsic and extrinsic camera parameters

I saw the paper, and there is a formula for calculating the focal length. There is a sentence:"we ask the participant to place their head d cm away from the camera". I can't find the detailed number of d. Did i miss something?

Hello, you might ask the process to get the focal length f. We use the code, https://github.com/chihfanhsu/gaze_correction/blob/master/gaze_correction_system/focal_length_calibration.ipynb, to obtain f and d also is listed in the code.

Besides, the actual estimated focal length is listed in the code, https://github.com/chihfanhsu/gaze_correction/blob/master/gaze_correction_system/config.py, and the estimated f is 650.

You might need to change f to fit your computer.

Thanks a lot!
