A few people mentioned this so I decided to test it.
First of all, marker tracking as a whole.
It works great
- cross line
- parallel lines
- global marker scan
All of them work pretty identical, they easily see the markers.
They see both the 3mm and 6mm ones.
The 3mm markers stop being recognized when you’re too far, but getting back closer shows them again.
So basically everything works as it should, as one would expect.
Now the Full field mode.
It’s bad.
Like not even close.
As soon as you switch to full field (normal marker tracking or global marker tracking) Revoscan just doesn’t see the markers.
There is pretty much no way to get it to see the 3mm markers, it sees the 6mm ones but it’s really struggling.
Look at it - all these markers visible in the depth camera, but only a single marker found by Revoscan.
We even get the 3d scan of the marker stickers faster than we can get the track to work.
At most I managed to get 4 markers to show up at the same time - still not enough to make the track work - and even then they were really touch and go - they kept disappearing all the time.
Now changing absolutely nothing I switch to Parallel Lines mode:
Boom, a bunch of markers are visible.
Same set up, same scanner position, same everything.
I noticed that when I’m creating the Global marker cloud, the scanner has no blue light on, so marker tracking is completely separate from the scanning modes - if so, then I see no reason why there would be such a big difference between the modes.
Now I have been able to scan things in auto turn table mode using markers before - so it’s not like markers don’t work at all in Full field mode - it’s just that they work waaaaay worse than they should imho.
PS. I also checked my set up in Miraco and Mini - both of these scanners had no problems tracking these markers - so the probem is unique to MetroX full field mode.
