May 2022 (ARCore SDK version 1.31) changes to Depth
Stay organized with collections
Save and categorize content based on your preferences.
The changes outlined in this document are only applicable to apps compiled with ARCore SDK version 1.31 or higher. Apps compiled with an older version of ARCore will not be affected.
As part of the May 2022 1.31 release, the maximum range of ARCore’s depth has been upgraded from 8.191 meters to 65.535 meters. The Depth API now uses all 16 bits per pixel to represent depth, where previously only 13 bits were used for depth values. Though apps using the following methods in older ARCore SDKs will still work using the previous depth range, we recommend updating them in your codebase for better functionality.
