* For camera devices that support the

* capability, DEPTH_POINT_CLOUD coordinates have units of meters, and the coordinate system is
* defined by the camera's pose transforms:
* {@link android.hardware.camera2.CameraCharacteristics#LENS_POSE_TRANSLATION} and
* {@link android.hardware.camera2.CameraCharacteristics#LENS_POSE_ROTATION}. That means the origin is
* the optical center of the camera device, and the positive Z axis points along the camera's optical axis,
