Depth Evaluation

[illuSION-crypto]

Hello, I am training a NerfFacto model using NerfStudio, and I have ground truth depth maps in my data. I would like to evaluate the accuracy of the depth maps generated by NerfFacto. However, I noticed that the output depth maps have values ranging from 0.8 to 1.3. How can I obtain depth maps in the true scale? Alternatively, how can I determine the scale to which NerfStudio normalizes the data?
