how to deal raw data(mist/depth image）

[songWell]

hi,
Thank you for providing the dataset.
Now, I rectify equirectangular panoramic images, but I think the value in depth is wrong（I'm new to panoramic images and don't know how to deal with them）, so should I do something like multiply by a ratio or use an intrinsic matrix?
For example, in ("Tiny" Partition) Tolstoy scene, the depth value in the red circle is 1800. I think it should be 3600, so how to rectify?

I found it, is 1/512m?

Depth: Depth images are stored as 16-bit PNGs and have a maximum depth of 128m and a sensitivity of 1/512m. Missing values are encoded with the value 2^16 - 1. Note that while depth is defined relative to the plane of the camera in the data (z-depth), it is defined as the distance from the point-center of the camera in the panoramics.
