archeological objects
« on: December 02, 2013, 06:29:29 PM »
Hello!

I am currently working in 3d-documentation of archaeological objects.
I'm having problems with getting the shape of an object similar to the following forum thread http://www.agisoft.ru/forum/index.php?topic=538.msg2361#msg2361.

I need to get the inside and outside of the piece. I have to take pictures from the front, top and bottom?

Hello archaeological_pt,

Could you please post any sample image of your object so that we can understand better the shape of the object?

Thank you Alexey Pasumansky

Hello archaeological_pt,

I think you should take several circles of images from different heights, also you'll need to roll the object over to take pictures of the bottom from out side.
Processing both subsets in a single chunk will require masking out the background prior to processing.

As for the inner part, it will be included in the result if you have good quality images that contain both outer surface of the object and inner parts (opposite sides). Both these surfaces should not be blurred, so you'll need to use higher F-stop values.
