Question about camera extrinsic parameters of MultiviewX.

[Yamameeee]

I visualized camera poses and positions provided by this repo using viser.
As shown in this visualization result, cameras are facing in the opposite direction of the region of interest.
In addition, unlike Wildtrack and GMVD datasets, the Z-axis representing the height in the world coordinate system is also inverted.
(Camera positions in the world coordinate system appear to be correct.)
Are the camera extrinsic parameters correct?

I found that when converting the pedestrian's position in the world coordinate system to the camera coordinate system using the camera extrinsic parameter, the Z-components of almost all pedestrians are negative, meaning the position is opposite to the direction the camera is facing.
This means the camera extrinsic parameter is wrong, right?

Thank you for your interest. I think you're right. You are welcome to suggest a set of updated parameters and I'll update the dataset zip files.

Thanks for your reply.
Could you please advise me on how to make corrections?

Feel free to provide a link to the updated camera parameters in a zipped file.
