I decided to try making a 3D printed Scan Marker Net.
You might have seen them, they are commercially available, but I couldnt get one here in Australia.
So, I bought a very cheap garden net with 100mm hole size (that is 4 inch for the non-metric country folk)
Then I designed and 3D printed a couple of hundred “Snap Together” PLA buttons for the reflective markers. (Rhino 3D)
So far I have tried scanning a flat featureless floor (see attached) and it works a treat, no loss of tracking at all.
I will try some car panels tomorrow.
looking great! I was about to design that myself, allready bought a net for that purpose. do you intend to share these files? is it snap fit or did you glue the parts together?
Remember the markers need to be in an unique pattern for best tracking results .
The same pattern can snap the frame in the wrong places when you lose tracking just once …
I finally found some time to do a quick scan on my little Mitsubishi.
Once again, this scan was done outdoors, after sunset.
I was using the Range Scanner running on a 10 inch Android Tablet.
The car had no surface treatment at all.
This marker net worked perfectly. I did one continuous scan with only a couple of tracking loss errors.
The scanner (Range) re-established itself each time and continued scanning.
1200 Frames all in all, I am very happy with the result.
Wow nice Mike , I am surprised it worked
Thanks for sharing !
Using this net is so fast compared to manually placing Markers.
I was concerned about having the markers in a line, but it didnt seem to matter. My plan was to just warp the netting a bit if it didnt work first time.
I am not going to post the STL for the Buttons online,… but I am going to make a video about how to create them using Rhino 3D and post it on my website / youtube
I am planning on producing a series of “how to” create 3D models from Scan Data using Rhino, something I have been doing for over 20 years.
I am sure it going to be interesting Mike , it is always great to inspire people with a new idea !
Post your videos when you are ready Mike !
