Class VisionOSARKitCameraDevice

네임스페이스
easyar

VisionOSARKitCameraDevice는 VisionOS ARKit 기반 camera device를 구현하며, image, camera parameters, timestamp, 6DOF 위치 정보 및 tracking status를 포함하는 InputFrame을 출력합니다. 생성 후 start/stop을 호출하여 video stream data 수집을 시작하고 중지할 수 있습니다. 이 device가 더 이상 필요하지 않으면 close를 호출하여 닫을 수 있습니다. close 후에는 계속 사용해서는 안 됩니다. VisionOSARKitCameraDevice는 inputFrameSource를 통해 InputFrame을 출력합니다. 사용하려면 inputFrameSource를 InputFrameSink에 연결하십시오. bufferCapacity는 InputFrame buffer의 용량을 나타냅니다. 이 수보다 많은 InputFrame이 이 device에서 출력되고 해제되지 않으면, 이전 InputFrame이 해제될 때까지 이 device는 새 InputFrame을 더 이상 출력하지 않습니다. 이로 인해 화면이 멈추는 등의 문제가 발생할 수 있습니다.
