Hi Walter
You misunderstand it! The customer demands the 4 seconds.

Hey there,

I haven't posted in quite a while but was interested in this thread since I have recently started a new job for a company that makes orthotic braces. One of the things I hate the most about the process is the fact that we scan plaster molds of the patients lower leg and the data is not very "clean". Though I know it won't happen over night I look forward to a future where scans can be captured of the actual patients foot rather than a poor quality casting.

Also...

@Walter
I currently don't have the time or skill to achieve a quality foot scan such as yours so I am wondering if you might be willing to share one of your foot scans with me. I would like to show it to my coworkers. I understand if you can't since you and Sven may want to keep your feet proprietary :)

I'm enjoying seeing what everyone is coming up with. Keep up the great work.

Hi Darin,
Sven's foot hasn't proprietary rights. :wink:
And if you can use it in your company, here it is. I have compressed it from 23.1MB.

Here we have a SL scan of a hand with texture. Scanned from 7 positions á about 45°. The settings and the equippment were the same as of the low shoe before.

No problem to capture the texture images. The video projector goes automatically to a white bright light.

@Walter

Thanks so much for sharing your foot scans. Very nice of you.

Great work as usual on the hand too.

Hi Walter :D
I apologise for having written it in the topic. I do not do it after this.

Ok Tibor, no problem. You are doing very interesting things and of course this thread isn't my thread, everyone can post here. But we shouldn't mix too different things, the forum is big enough to open a new thread.


Now I have extended my turn around scanner with a seat and a back and head rest to be able to do 310° head scans. Just to scan from behind isn't possible because of the wooden slats of the back rest. The person has to lift both feet for a moment when the horizontal aluminium arm is approaching.
Nearly all parts for this extension are from an old kitchen chair. The wooden baseplate of the seat is mounted by a flange on the steel tube of the sunshade pedestal. Because the hight of the seat is constant I had to find a possibility to adapt the hight of the camera and the video projector. This problem was solved by a second square tube plugged into the former aluminium tube. Both aluminium tubes are telescopically adjustable.
Two wheels from an old office chair stabilize the rig against shaking after a turn stop. The minimized head rest is made of an "anatomically" shaped steel wire. And if she or he has long hair it's even possible to comb it over the wire bow so that the sides of the head rest aren't visible after scanning.
The stability of the head rest should be sufficient because this chair isn't a dental treatment chair where the patient attempts to escape from the burr. :mrgreen:

Let's see if it works.

Walter

Edit: If someone likes to recreate the setup:
Because the vertical steel tube isn't often really exactly vertical, it can happen that the wheels are not always touching the floor when the rig is turned. Therefore it's better not to fix the steel angle at two anchorage points. Means remove the steel angle and use a simple hinge at the horizontal alu arm. On the left side of course. :wink:

Here we have a SL turn around scan of a person. It was made with 7 scans of about 45° and two additional scans under the chin and from above on the head. Both latter were made without to change the rig. Simply by leaning the head forwards and backwards.

You can clearly see the headrest, maybe with a special software it can be concealed.

Hello Walter,
Very nice scan of the head and nice chair setup! To make them did you use the same David SL settings that you mentioned earlier in the thread?
"19 different horizontal stripe patterns: 6 sec."

It looks like you posted the scan before Sven came out with David 3.1 with the non-inverse option, few patterns faster scan, have you had a chance to try this yet with your head scanner? I'm interested in your scan settings cause the results are so good, thanks for posting picks of your rig too!

Hi Max,
Thanks, and yes, the settings were the same as for my low shoe.
I had used version 3.0 with the coded light mode "inverse". In the meantime I had tested V3.1 with the "non-inverse" mode by a scan of a wooden nutcracker:

Do you know which famous man this "tool" shall portray? :wink:
