ThreeDofCameraDevice Class¶
Description¶
ThreeDofCameraDevice实现了一个three dof的camera设备,输出 InputFrame (包含图像、摄像机参数、时间戳、位姿转换矩阵和跟踪状态)。
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。
ThreeDofCameraDevice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 。
