Class InertialCameraDevice

Namespace

easyar

InertialCameraDevice implements a camera device based on motion inertia, outputting CameraTransformType as FiveDofRotXZ InputFrame (including images, camera parameters, timestamp, pose transformation matrix, and tracking status). After creation, you can call start/stop to start and stop collecting video stream data. When the device is no longer needed, you can call close to shut it down. After close, it should not be used anymore. InertialCameraDevice outputs InputFrame through inputFrameSource, and inputFrameSource should be connected to InputFrameSink for use. bufferCapacity represents the buffer capacity of InputFrame. If more than this number of InputFrame are output from the device and not released, the device will stop outputting new InputFrame until the previous ones are released. This may cause issues like screen freezing.
