ARKitCameraDevice Class

Description

ARKitCameraDevice实现了一个基于ARKit的camera设备，输出 InputFrame （包含图像、摄像机参数、时间戳、6DOF位置信息和跟踪状态）。

创建之后，可以调用start/stop来开始和停止采集视频流数据。

当不再需要该设备时，可以调用close对其进行关闭。close之后不应继续使用。

ARKitCameraDevice通过inputFrameSource输出 InputFrame ，应将inputFrameSource连接到 InputFrameSink 上进行使用。参考 概览 _ 。

bufferCapacity表示 InputFrame 缓冲的容量，如果有超过此数量的 InputFrame 从该设备中输出并且没有被释放，该设备将不再输出新的 InputFrame ，直到之前的 InputFrame 被释放。这可能造成画面卡住等问题。参考 概览 _ 。
