I've reconstructed a 3D model and used scale bars.
Automatic marker detection worked fine.
I've chosen the two scale bars and entered the distance between them.
Also indicated one marker as the origin and another the axis I want.
I would have thought MetaShapePro could have calculated the camera positions for me ... if so, how? If not, why?
ps: I tried to upload a screen dump, first the system told me the maximum upload was 768KB, so I jpeg compressed it some more, then I got the error the maximum upload limit is 512KB. A bug somewhere. I'm trying a much smaller file now.
