Quastions regarding ./assets/scannet_test_pairs_with_gt.txt.

[zhangsngood]

Thank you for your excellent work! I would like to know how the relative extrinsic parameters in ./assets/scannet_test_pairs_with_gt.txt are obtained. If I know the camera positional extrinsic parameter of two images, how is the transformation extrinsic parameter of these two positions. Does anyone have any idea about it?

Given R, t of two images, the relative pose should be calculated
