Re: [MORPHMET] 3D surface scanner information

[mf]

Hi Miguel,
If you're going to do morphometrics on teeth, be aware that they are  
tricky to scan. Many scanners don't handle specular/translucent  
objects all that well.  Blue light scanners (eg HDI100 series,  
Breuckmann) tend to do better in that respect.

Hello everyone

I am interested to obtain a 3D surface scanner which will be used to study
hominin teeth and skulls. Does anyone have any experience, suggestions
and/or recommendations?

For instance price, resolution, peformance, manipulation (portable)


thanks in advance

Miguel

RE: [MORPHMET] 3D surface scanner information

[Robert Z. Selden, Jr.]

Hi Miguel,

I've been using a Creaform GoSCAN50, and am very happy with it (I scan ceramics 
though; not hominins). There are two of these scanners (GoSCAN20 and GoSCAN50 - 
see 
http://www.creaform3d.com/en/metrology-solutions/handheld-portable-3d-scanner-goscan-3d);
 the 20 gets better detail on smaller objects, and the 50 is better for 
medium/large objects. Depending on the level of detail that you need 
(particularly for the teeth), it might be better to opt for the 20. I recently 
used a 20 to scan a projectile point (https://skfb.ly/ATNV), and it worked 
quite well. 

A few examples from the GoSCAN50 here:

Ceramic vessel from Salvador, Brazil (takes a moment for the texture file to 
load) - https://skfb.ly/AGtZ 

Caddo effigy pipe (frog) from Louisiana (US) - https://skfb.ly/JMvv 

Caddo ceramic bowl from Texas (US) - https://skfb.ly/JM6W  

Some of my colleagues have produced some good scans with the NextEngineHD 
(http://www.nextengine.com/); these from Bernard Means: 

Racoon Skull - https://skfb.ly/EoVw 

Owl Skull - https://skfb.ly/EoVP

There are also some good examples of folks using photogrammetry (123D Catch, 
AgiSoft, etc.) for this kind of application; although I don't have those handy. 

Yet another option would be to see if there is anyone on campus (engineering 
departments usually have quite a few) that might be willing and able to help. 
While I was in grad school, we ran across a CT scanner in the petroleum 
engineering department that they needed to justify purchasing, so they let us 
run as many samples as we wanted to at no cost. The art department also had 
quite a few scanners. 

It all comes down to what you have experience with, and what you're most 
comfortable with; particularly since you will be spending quite a bit of time 
with this equipment. There are advantages and drawbacks to every surface 
scanner and photogrammetry program. If you have an opportunity to demo a 
scanner or photogrammetry program, I would take it (there may be a variety of 
product reps in your area). 

As things get published, we've been uploading our scan data to Zenodo 
(https://zenodo.org/collection/user-caddo_nagpra_3d); bound to be other 
examples there and elsewhere that you can explore. 

Best of luck,
Zac

Re: [MORPHMET] 3D surface scanner information

[Thomas O'Mahoney]

Hi,
This subject pops up every few months on Morphmet. The general consensus is
that either Creaform or structured light scanners like Artec or LMI have
made are generally very satisfactory solutions. People like Breuckmann are
an order of magnitude more expensive but also very good.
You'll want to budget at least $20-30,000 to set yourself up properly with
both scanners and workstations/post-processing software. Popular post
software include geomagic and polyworks. They work extremely well but cost
$$$. For CT, Amira/Avizo has a minimal learning curve but again costs $$$.
I can't give exact prices as they will give you a bespoke quote depending
on number of workstations etc. Stradwin is a nice freeware solution for CT
if your scans don't have too many problems (e.g. fossil embedded in matrix,
low contrast).
For fossil hominins, bear in mind that a large proportion have been either
CT or MicroCT scanned, and curators will be loth to allow surface scanning
on top. So a CT program is useful for processing already existing scans.
Photoscan is worth playing about with, as it only costs $50. With a good
protocol you can get some extremely good results from skulls and mandibles
(think good camera and lazy Susan).

Disclosure-I run a small consultancy on 3d imaging and work with LMI in the
UK.

All the best,
