intrinsic parameters of each Kinect

[xiaochehe]

Hi, thank you for providing awesome dataset!
I want to re-project 3D skeleton to 2D.
How do I get the information of intrinsic parameters of each Kinect?

Thanks in advance for considering!

You can extract the keypoints detected by the kinect in 3D and 2D for each camera setting S001-S017. These can be used with opencv stereo camera calibrate to estimate the camera matrices.

@xiaochehe did you get the intrinsic parameters of the used cameras Microsoft Kinect v2.

I want the following values
{
'id': '',
'center': [],
'focal_length': [],
'radial_distortion': [],
'tangential_distortion': [],
'res_w': 0,
'res_h': 0,
'azimuth': 0, # Only used for visualization
}

Can you please provide an example?

3DKeypoints Z values are not in the same plane。I can't set Z=0

I've encountered the same issue, have you managed to solve this problem?
