Object Recognition | AR Model's size Too Big

Unity Engine

Regarding 3D object recognition, after scanning the 3D objects, I get the “*.arobject” file . And back to the unity scene, I add the AR 3d models to match real 3dobject.But there is a strange phenomenon,It’s hard to adjust the ar model’s size (too big )to fit the real object, In order to match the scanned object, I need to zoom out ar model to many times smaller to adapt. so that we can’t do a lot of pretty effects.

In Image Recognition we can adjust the “Physical Size” to fit our ar models.but In Object Recognition we can’t find the solution.

There is no physical size parameter for reference objects because ARKit determines the size of the object as part of the scanning process. The ARKit XR Plug-in does not provide an API to resize an object after it has been scanned, so within Unity your best option is to change the scale of the GameObjects in your scene appropriately.
