The recommended minimum target size is 12cm in width, but there are steps you can take to improve detection and tracking of small targets.

In general, you'll get the best performance by scanning at a maximum range of 10x you target width (so in your case 18cm). Could you try scanning closer to your targets and see if the wobble goes away (or at least diminishes)?

Lighting is another potential issue. I noticed in your screenshot there is a direct light hitting very close to the target you are seeing the issue on. Try moving the target away from this direct lighting and see if you get better detection on it.

The images all got five stars from the target manager, but they are the size of scrabble tiles, ~1.8cm x 1.8cm. I'm scanning them from about 1 foot away. It's very important for my app that the markers be that size or smaller, so please let me know if there any sample markers I can use that will work better.

Hello simille4,

What rating did the Target Manager give your images when you uploaded them to a database? What distance are you scanning these from and how large are the images?

Thanks,
