Class InertialCameraDevice

Namespace
easyar

InertialCameraDevice implements a camera device based on motion inertia, and outputs CameraTransformType as FiveDofRotXZ of InputFrame (including image, camera parameters, timestamp, pose transformation matrix and tracking status). After creation, start/stop can be called to start and stop collecting video stream data. When the device is no longer needed, close can be called to close it. It should not be used continuously after close. InertialCameraDevice outputs through inputFrameSource InputFrame, and inputFrameSource should be connected to InputFrameSink for use. bufferCapacity indicates the capacity of the InputFrame buffer. If there are more InputFrame output from the device and not released than this number, the device will no longer output new InputFrame until the previous InputFrame is released. This may cause problems such as screen freezing.
