XR Camera Subsystem

The camera subsystem is responsible for managing a hardware camera on the AR device. It provides the following data concerning the camera:

• Camera image (as an "external" texture on the GPU).
• Camera image (as a buffer of bytes available on the CPU).
• Projection matrix, used to set the field of view and other properties of the virtual camera according to the physical one.
• Display matrix, used to orient the camera image correctly.
• Camera intrinsics describing a mathematical model of the camera. Useful for computer vision algorithms.
• Camera conversion utilities, for converting the CPU image to RGB and grayscale.
• Light estimation information (color and brightness of the environment).
• Camera focus mode (i.e., autofocus vs fixed)

See the Script API Reference for API details.

Note

Starting November 2022, the camera image will not be available on Android platforms due to API deprecation in ARCore SDK. Update to package version 4.x or higher to use supported version of the API. See https://developers.google.com/ar/develop/unity-arf/ndk-camera-deprecation.

The camera image APIs will not be affected on iOS platforms and will continue to work same as before.
