Tanks and Temples Cams_1/ file data

[j-sripad]

The 00000000_cam.txt camera file for the Family scene in the tanks and temples intermediate test set is as follows:

extrinsic
0.999914 -0.000314413 -0.0130934 -0.0371895
6.96597e-06 0.999724 -0.0234745 -0.127538
0.0130972 0.0234724 0.999639 0.570572
0.0 0.0 0.0 1.0

intrinsic

0.0 1167.35 541.296
0.0 0.0 1.0

0.394995 0.874995

The last line has the depth_min value = 0.394995 and the depth_max value is 0.394995
How was the depth_max value calculated given I already know the depth_min value?

Thanks

The depth range in 00000000_cam.txt comes from the output of COLMAP SfM, please refer to MVSNet input from SfM output and the corresponding script for more information.

I ran colmap on one of the scenes from the intermediate test set of tanks and temples. After which I ran the script. The resultant cams file has different depth_min, depth_interval values. The extrinsics are also varying widely.
