Class InertialCameraDevice

名前空間
easyar

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