A value specifying whether and how the session attempts to automatically detect flat surfaces in the camera-captured image.
- iOS 12.0+
By default, plane detection is off. If you enable
vertical plane detection, the session adds
ARPlane objects and notifies your
ARSKView object whenever its analysis of captured video images detects an area that appears to be a flat surface.
In an object-scanning session, you can use detected planes to help determine where the origin (anchor point) for a scanned object should be relative to its extent.
