Are the depth maps of the MVS-Synth Dataset metric? What is the metric scale of the depth exr file?

[guangkaixu]

Hi, thanks for your great work. The maximum of the depth exr file can be larger than 10000. How can I get the metric scale of the depth, so that I can obtain metric depth with:

metric_depth = depth_read_from_exr / metric_scale

Thanks a lot!
