should I see the whole object with all camera? can I zoom?
« on: January 28, 2014, 12:07:42 PM »
Hi,

In case of a head scan, with 30 camera for example.
Should the whole head be visible on all the pictures or can I zoom and take only a part to maximise information about the head?
Since a lot of pictures will overlap.

Can I zoom? and by that I mean, can I have a different level of zoom on each camera or should it be the same for all of them?

Thanks.

It all depends on your cameras (resolution wise). I think you need to experiment but if you have 30 cameras, 20 being minimum (5 above each other on 4 sides) you have 14 to spare for zooming in for details.

I would setup 5 vertical cameras on 6 sides so you get enough horizontal and vertical overlap or 4 vertical on 8 sides.

5 vertical on 6 side is enought for a head scan?
won't you miss some part of the chin?

Right now I'm using this kind of rig (see attachment)
