Surface/Motion Tracking - Get Real 1:1 object scale size

Question

We are facing problems regarding placing markerless object, we tried:

- Surface Tracking: we got it working but the content object is scaled imprecisely and we want the object to keep a 1:1 aspect ratio from unity to the world space

- Motion Tracking: the scale issue seems resolved using motion tracking VISLAM, but the content objects are genereted mid-air (above ground) instead than on the ground, also we would like to work with iOS as well and motion tracking has not specified if it's supported by ArKit as well.

What are we asking?

What would you think could be our best attempt to get a 1:1 scaled object placed in AR on the ground?

Answer 1

Hit test against the point cloud or horizontal plane is supported in motion'tracking. You can place objects on a plane or point cloud to achieve fit，

Thanks,
I still have the object placed on the plane floating above the ground.
Also is this technology coming for iOS as well?

An object will be placed in the air when the sample is started, and then the plane can be prevented from being on the plane after the plane is detected.
Only supports Android, ARKit on ios is good enough.
