龍源治間歩
This scan shows the entrance of one of the two walkable shafts in Iwami Ginzan silver mine world heritage site. Exit is at the other side of the hill.
I post processed it with MeshLab, but there are still many wholes I didn't manage to close. I think it shows the limits of scanning with Tango. Hope to get approval to shoot it again for Photogrammetry this summer.
