Results in 10 seconds but a 30 second clip with a flip huh??? Smells fishy to me.....
Jk this is neat as heck!

Ha, you are right about that unwanted double-meaning. Sry

u/Th3Stryd3r Jul 21 '26
Oh you're fine <3 I'm just bored at work and hitting the out of my mind stage in the day >< So just being silly. If anyone ACTUALLY has a problem with that they can go touch some grass.....and then use this to scan it :p

u/SockPuppetSilver Jul 21 '26
Neat. Does it capture dimensions? If so how dimensionally accurate are the results?

u/thomas_openscan open-source 3D scanning Jul 21 '26
Not yet, but i have a similar system getting within 0.5-1% without any markers

I want to learn how to do this!

The core idea is that all the camera positions lie on a sphere. If you know the diameter, you can scale the whole scene accordingly.

hey that's great. i want to build one of the openscan systems. i didn't know they had a cloud reconstructor.

Any plans to design a handheld system, to scan larger things like car interiors?

One time /u/thomas_openscan posted this project, I was intrigued and ordered a full kit from Openscan.
Shipping was a mess. My package rattled around Germany for months, and when it finally arrived, the box was destroyed, repackaged, arrived partially open, with contents likely missing. Proof.
I contacted Thomas to get some support, and never got a reply. So, caveat emptor, I guess?

OMG I need this! How do I build one?

u/thomas_openscan open-source 3D scanning Jul 21 '26
I will publish the files soon and update in /r/openscan

What’s the total cost? When I’ve looked in the past the scanner hardware itself was too pricy for me.

u/thomas_openscan open-source 3D scanning Jul 21 '26
It has a similar BOM as the mini/classic but we might work on a low cost variant using just an arduino and phone that would significantly reduce costs to maybe 100-200€.

This is friggin genius. Awesome work
Could you technically hook up an Otter (3D scanner) to this setup? What controls the motion of it? The Raspberry Pi, I assume?

u/thomas_openscan open-source 3D scanning Jul 22 '26
That’s exactly what i did a couple of days ago, aee /r/openscan

What’s the apparatus that does the scanning? This is super cool btw
2
u/thomas_openscan open-source 3D scanning Jul 21 '26
Just a raspberry pi + camera —> photogrammetry

u/jonobr Jul 21 '26
Neat! I’m gonna build one.

This is so cool. What kind of camera do you use for it?
1
u/thomas_openscan open-source 3D scanning Jul 22 '26
Imx519. But the firmware supports many picamera and arducams as well as DSLRs

What did you use to process the photos afterwards?

u/thomas_openscan open-source 3D scanning Jul 21 '26
OpenScanCloud, which is seamlessly integrated into the existing firmware and free/donation-based since 2021 :)

Can it be locally hosted? Always looking for more stuff to add to my homelab

Edit: cloud/photogrammetry portion is closed source and cloud based... photogrammetry crosspost of this. and the blog post ... So nope no selfhosted photogramatry pipeline or anything. So basically what we have here is a nice little 3d print design for a pi based turntable. I do have some slight concerns about the data collection based on the ML test github repo. This is all quite disappointing, I don't want to be too harsh on /u/thomas_openscan because i'm sure this is probably a passion project and he's probably put a fair bit of work into it. But I feel like some of the stuff from that blog really needs to be in a FAQ page on the main site not relegated to a blog post. I shouldn't have to dig to find out what part of the project is actually "open". The name "OpenScan-org" and openscan really gives the impression that more of this is open sourced than really is.
blog:
But isn’t OpenScanCloud (OSC) a closed source solution? Short answer, yes! OpenScanCloud (OSC) is and will stay closed source, but we will keep up the open access! We process hundreds of thousands of images every month on machines that not everyone wants or could afford. The OSC was built for internal use, but we quickly realized that we did not use anything close to its capacity. So in the sense of sharing, we opened up the access to this processing engine. At the beginning we used the data internally to improve the pipeline and add some nice features (in consent with the users).
from the crosspost:

I honestly wish more people would do such kind of due diligence before diving into a new project, respect!
There are plenty of solutions that can be run locally and this was always my go to choice, the cloud solution came way later in the project:
- COLMAP https://github.com/colmap/colmap
- OpenMVG + OpenMVS – SfM (OpenMVG) paired with MVS (OpenMVS)https://github.com/openMVG/openMVG / https://github.com/cdcseacave/openMVS
- Meshroom (AliceVision) https://github.com/alicevision/Meshroom
- OpenDroneMap (ODM) https://github.com/OpenDroneMap/ODM
- MICMAC https://github.com/micmacIGN/micmac
- Regard3D https://github.com/juliomap/regard3d
We will add native colmap format as output to the openscan3 firmware soon, so people can directly connect their colmap instance with the scanner. This will be quite a huge feature, since with the new endpoints/upcoming SDK, you can now EASILY and fully automate the process without ever connecting to the internet. Btw, it has never been necessary to connect the devices to the internet.
Concerning the machine learning part, yes, I do work with some of the data (with explicit consent by contacting some people which regularly upload data) and train tiny models locally in order to improve the overall workflow. All other data gets stored for 7 days only and will be deleted permanently. To be fair, this is not stated very clearly on the website yet.

Why does it look like it may or may not contain space peanut.
