Using ARKit, what is the max recommended distance from the plane/wall, beyond which accuracy starts to diminish?

Hi All,


I have created a measurement application using ARKit, which measures the height and width of objects.

It works as expected on smaller surfaces, in well lit rooms at a distance of 3-5 feet.


The plane detection/feature point accuracy starts reducing in open environments (sunlight) at distances over 10 feet, worsens with increasing distances.


I have tried searching, but have not found any data related to optimal operating distance/environment for ARKit.


Can somebody point me to the right resource from where I can get this information.


Regards,

Ishan

I don't think there is a max distance hard spec - instead, tracking reliability is an aggregate based on how efficient the device is at processing video frames, excessive motion—too far, too fast, or shaking too vigorously, blurred image, etc.


Are you using trackingState?
