Class InputFrame

Namespace

easyar

Assembly

EasyAR.Sense.dll

Input frame. Contains image, camera parameters, timestamp, camera transformation relative to world coordinate system, and tracking status. Among them, camera parameters, timestamp, camera transformation relative to world coordinate system, and tracking status are all optional, but specific algorithm components have specific requirements for the input.

Methods

Clone()

public InputFrame Clone()

Returns

CloneObject()

protected override object CloneObject()

Returns

cameraParameters()

Get camera parameters.

public virtual CameraParameters cameraParameters()

Returns

cameraTransform()

Camera transformation relative to the world coordinate system. The camera coordinate system and the world coordinate system are both right-handed coordinate systems. The origin of the camera coordinate system is the camera's optical center, the positive direction of the x-axis is right, the positive direction of the y-axis is up, and the positive direction of the z-axis is the direction the light enters the camera. (The right and up here refer to the right and up in the camera image, which may be different from the device's natural orientation.) The data arrangement is row-major, opposite to OpenGL's column-major.

public virtual Matrix44F cameraTransform()

Returns

cameraTransformType()

Camera transformation type.

public virtual CameraTransformType cameraTransformType()

Returns

createWithImage(Image)

Create, only contains image. The input created by this method can only be used for CloudRecognizer_, and other functions cannot work.

public static InputFrame createWithImage(Image image)

Parameters

image

Returns

createWithImageAndCameraParameters(Image, CameraParameters)

Create, only contains image and camera parameters. The input created by this method can only be used for CloudRecognizer_, and other functions cannot work.

public static InputFrame createWithImageAndCameraParameters(Image image, CameraParameters cameraParameters)

Parameters

image

cameraParameters

Returns

createWithImageAndCameraParametersAndTemporal(Image, CameraParameters, double)

Create, only contains image, camera parameters, and timestamp.

public static InputFrame createWithImageAndCameraParametersAndTemporal(Image image, CameraParameters cameraParameters, double timestamp)

Parameters

image

cameraParameters

timestamp

Returns

hasCameraParameters()

Whether to include camera parameters.

public virtual bool hasCameraParameters()

Returns

hasSpatialInformation()

Whether to include spatial information (cameraTransform and trackingStatus).

public virtual bool hasSpatialInformation()

Returns

hasTemporalInformation()

Whether to include time information (timestamp).

public virtual bool hasTemporalInformation()

Returns

image()

Get image.

public virtual Image image()

Returns

index()

Index, an auto-increment, different for each input frame.

public virtual int index()

Returns

motion()

Motion input data.

public virtual Optional<MotionInputData> motion()

Returns

timestamp()

Timestamp. Unit is seconds.

public virtual double timestamp()

Returns

trackingStatus()

Get device motion tracking status: MotionTrackingStatus_.

public virtual MotionTrackingStatus trackingStatus()

Returns

tryCreate(Image, CameraParameters, double, Matrix44F, CameraTransformType, MotionTrackingStatus)

Create.

public static Optional<InputFrame> tryCreate(Image image, CameraParameters cameraParameters, double timestamp, Matrix44F cameraTransform, CameraTransformType cameraTransformType, MotionTrackingStatus trackingStatus)

Parameters

image

cameraParameters

timestamp

cameraTransform

cameraTransformType

trackingStatus

Returns
