ARCoreCameraDevice Class¶
Description¶
ARCoreCameraDevice实现了一个基于ARCore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）。
使用时需要先使用java.lang.System.loadLibrary加载libarcore_sdk_c.so。
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。
ARCoreCameraDevice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 。
注意：当前ARCore(v1.13.0)的实现在创建和销毁session时存在内存泄漏，多次创建和销毁会导致内存占用不断增长且销毁后也不释放。

isAvailable¶
检查是否可用。只在Android系统上并安装了ARCore时返回true。
在没有加载libarcore_sdk_c.so时调用会返回false。
注意：如果设备不支持ARCore，但却通过旁加载方式安装了ARCore的apk，则该函数会返回true，但ARCore不能正常使用。
