Discussion Which is the best image marker type/format for ImageTarget?

As title said, I'm looking for which one is better than the other about use of image marker.
It can be fiducial marker, RGB-colored image, or any custom marker.
I'm still looking for by conducting self-experiment, but also I want to know if anyone here have tried or discovered before.

Notes: In terms of using image marker for AR, it's not only fast recognized, but also stable tracking, as we want to acknowledge their position and rotation.

 

There is a lot of good information here regarding ARCore if you are building for Android:

https://developers.google.com/ar/develop/augmented-images#tips_for_selecting_reference_images

• Color is not used with ARCore
• at least a 300x300 PNG / JPG (I recommend PNG to avoid compression artefacts)
• Use arcoreimg to check if it is likely to be recognized well (Though this tool should only be used as a rough guide)

ARKit provide some similar guidelines somewhere. However, in general, image tracking is a lot more reliable with ARKit, so I've found that generally if you have a marker that works well on Android, it should track fine on iOS in most cases.

 

I see.
That's a good reference for me.
Thank you very much!
