Apple is looking to add Apple AR technology to the Measure app on iPhone, making it more accurate and automatically annotating objects with their measurements.
The Measure app on iPhone became useful, and more accurate, once LiDAR was introduced. Now Apple has been researching bringing its Apple AR technology to make it faster and more accurate.
In the future, pointing your iPhone camera at an object could automatically get you an on-screen notification of its measurements. It will do it through AR, and it will do it in part through Machine Learning on different types of objects.
"Automatic measurements based on object classification," is a newly-revealed patent application. It's concerned with how to determine which object you're interested in, then how measure it accurately.
The patent application is particularly broad, including "devices, systems, and methods that obtain a three-dimensional (3D) representation of a physical environment." The detail generated is based on a whole series of different sensors and measurements to do with "depth data and light intensity image data."
