Face and Body Scanning / Re: 8mp iPhone results - Promising start but....

Hi Jon

No I do not intend to sever the hand to scan it!  The turntable allows the hand to be scanned whilst still attached to the body.  I mount the iPhone on the turntable (actually I have just built the mount to hold two iPhones) and rotate around the intact arm.  Picture below.

I am also including lighting but need to diffuse the light source as it is too intense.

Will post some developments as they occur.

Dear Jon

Thank you for your very informative response.  I will definitely follow up on the posts on the scale as I need to get accurate models.  Yes of course higher resolution cameras would be beneficial but I did start this work with a Nikon D750 full frame camera with a lovely lens.  I did get good results but I thought I would try with the iPhone because I am trying to get a system that will be available to clinicians without investing in $2000 + cameras.  I was pleasantly surprised with the outcome.  I also found an app that enables you to output from the iPhone as raw and fix the exposure and focus, so I am keen to keep working with the iPhone.  I really appreciate your response as I am sure you will agree, this is quite a lonely place to develop with such extremes in kit setup.  From massive cave systems with 100 dslrs to people scanning from drones.  Close up work is specialised and there is little out there to help.

Face and Body Scanning / 8mp iPhone results - Promising start but....

Hi, I have built a turntable rig to scan hands and am working with an orthopedic surgeon. The results are getting better and better.  I have attached a screen shot for information.  I want to use iPhones as I want to create a usable system that works with easily available cameras.  Please look at the image and help me make it better. BTW, I am using a mask to remove the background which is very effective.  I am using a stage prop hand at the moment and am building a rig to keep a human hand stationary.  I suppose my real question is, is this as good as it gets or could I do more to get greater resolution.  To be honest, we think that this is almost there.  Finally, the model comes out tiny, we have to scale it in the 3d printing program to get the right size.  How can I ensure the final model is correctly sized.  Lots of questions but we really are very excited with the results.
