Class VisionOSARKitCameraDevice

Namespace
easyar

VisionOSARKitCameraDevice implements a camera device based on VisionOS ARKit, outputting InputFrame (including image, camera parameters, timestamp, 6DOF position information, and tracking status). After creation, you can call start/stop to start and stop collecting video stream data. When the device is no longer needed, you can call close to shut it down. It should not be used after close. VisionOSARKitCameraDevice outputs InputFrame through inputFrameSource, and inputFrameSource should be connected to InputFrameSink for use. bufferCapacity indicates the capacity of InputFrame buffer. If more than this number of InputFrame are output from the device and not released, the device will no longer output new InputFrame until the previous InputFrame are released. This may cause issues such as screen freezing.
