Using smaller markers with Miraco

Discussions MIRACO Series
1

Hello, please forgive me if this has been answered elsewhere.

Has anyone had success tracking small markers using the Miraco in Near mode with marker tracking turned on, and if so how small can you go please?

The standard markers (6mm diameter) are too large for my use case, and I’d like to go smaller if the tracking cope with it.

Thank you!

Hello!
I successfully used 3mm Markers.
I ordered some 3M reflective Tape from Amazon and a 3mm hole puncher and made them myself.
It’s really cheap, the whole tape is only 14 bucks the hole puncher was under 10 bucks and you need small tweezers to get the backing paper off.
Works like a charm though.

Hi ingManiac!

Many thanks for this information, very useful! I’ll give this a try for sure.

I notice the original markers that ship with the scanner have a black ring around the reflective part - was it necessary to include this part?

Thanks again

In my case not. I use it on dark objects, so that could be the reason.
If you use it on white, it could be tricky for the scanner to see.
But at first place i used them on 3d printed parts (markerpyramids etc.) so i have a natural outline in black.
I can try this out on the weekend, i will let you know about the outcome.

Thank you, I’d be very interested in what you find. I have some reflective tape on order.

My object is light in colour so I think I may need something to outline, but let’s see.

Hello ingManiac,
great hack. I just gut received my miraco and I want to scan car items which probably needs lots of 6mm markers in far mode. Which colour of the reflective tape do you use? The link shows the blue one but I guess it is the silver one because of high infrared reflectivity?
I tried to use markers from MINI which I had left but failed. Marker were only recognized with very high exposure. It seems that the new marker have much higher reflectivity.

Thanks,
Thomas

Yeah, i use the silver one.
But in far mode 10mm markers are working too and for me they do a better job.
And remember, if you have a light object you need the black surrounding for the scanner to see the markers.
