I have the same problem with my vega with those dragon skin artefacts. The problem is while scanning you can’t undo the frames when you miss the tracking. It keeps scanning junk.
If you want accuracy, get a blue laser scanners. Dimensions scanned from infrared scanners will be affected by color and surface reflection. I get +/- 20 um from CR Scan Raptor.
how does the point cloud distance relate to the accuracy of the test? if you use the point cloud distance 0.18mm in Starvision, does that mean it rounds off all values to a resolution of 0.18mm or is it truly the 3 dimensional distance between all points?(in that case the error due to rounding would be much less) thanks for the measurements! it is very useful and gives me an idea if it can be used in my applications
No, it isn't related to accuracy. the point spacing is about 0.18 mm, for 1 sq.mm, it should have 25 points. The coordinate of the points at the extreme edge is fixed. Setting it too high would give a denser look, too low it would be difficult to see.
The noise on the back of the controller is due to a misalignment of scan data. Probably caused by a tracking failure or the controller moving very slightly relative the the markers. You need to lock your target to the markers to prevent the second issue. Ideally, the software needs better tools to remove this misaligned data before meshing.
No, external markers are not moving. I made another scan with Otter after this, no issue at all and I did another video when I put sticker markers directly on to the object, this artifacts shows up as well.
Love your channel!

It's refreshing to see someone really test 3D scanners and not just mindlessly repeat the talking points sent by the company.
Which consumer scanner has the most accuracy for scanning small parts (

@@Payo-TensileCreator Perfect. I already ordered the Raptor a few days ago. Just wanted to be sure I made the right decision buying it.

Love your channel! You should test the Revopoint MetroX when it comes out.
I saw it at Kick Starter, 689 USD, really good price.

Look how many other scanners he has. I assure you it's not his skills that are the issue with the result.
@@Payo-TensileCreator In that case it is a tracking failure, which was the first issue I mentioned.
Accuracy is way out on this Vega, another channel - Couch built, got 33.857mm scanned vs 33.88mm actual for a small object.
