Sorry for the inconvenience. We forget to include the information to docs.
Depth maps are stored as uint8 PNG images, where a value of 255 signifies an invalid pixel (i.e., out of range). For valid pixels, the depth in meters can be calculated by converting the uint8 value to a float and multiplying by $1000.0 / 255.0$:
$$ depth(u, v)=I(u, v) \times \frac{1000.0}{255.0} $$
We have observed that the transformation process introduced some numerical errors. We plan to upload a version with improved accuracy shortly.
Hello,
I have downloaded the depths from huggingface and I found that the depth maps have many stripes. it seems like they are out of the range of int8. How can I convert them to true depths?
We have released a new version of depth image with more accurate precision. Please refer to Getting Started to download the data. The usage of the data can be found in toturial.ipynb.
Hi, thanks for your excellent job. I noticed that the depth GT provided in the dataset is not the actual depth of the scene but values between 0-254. Could you please share about how do you use the depth GT for training?
