C# Класс AForge.Video.Ximea.XimeaVideoSource

The class provides continues access to XIMEA cameras.

The video source class is aimed to provide continues access to XIMEA camera, when images are continuosly acquired from camera and provided throw the NewFrame event. It just creates a background thread and gets new images from XIMEA camera keeping the specified time interval between image acquisition. Essentially it is a wrapper class around XimeaCamera providing IVideoSource interface.

Sample usage:

 // create video source for the XIMEA camera with ID 0 XimeaVideoSource videoSource = new XimeaVideoSource( 0 ); // set event handlers videoSource.NewFrame += new NewFrameEventHandler( video_NewFrame ); // start the video source videoSource.Start( ); // set exposure time to 10 milliseconds videoSource.SetParam( CameraParameter.Exposure, 10 * 1000 ); // ... // New frame event handler, which is invoked on each new available video frame private void video_NewFrame( object sender, NewFrameEventArgs eventArgs ) { // get new frame Bitmap bitmap = eventArgs.Frame; // process the frame }

Наследование: IVideoSource

Открытые методы

Метод	Описание
GetParamFloat ( string parameterName ) : float	Get camera's parameter as float value. The call is redirected to XimeaCamera.GetParamFloat.
GetParamInt ( string parameterName ) : int	Get camera's parameter as integer value. The call is redirected to XimeaCamera.GetParamFloat.
GetParamString ( string parameterName ) : string	Get camera's parameter as string value. The call is redirected to XimeaCamera.GetParamString.
SetParam ( string parameterName, float value ) : void	Set camera's parameter. The call is redirected to XimeaCamera.GetParamFloat.
SetParam ( string parameterName, int value ) : void	Set camera's parameter. The call is redirected to XimeaCamera.SetParam(string, int).
SignalToStop ( ) : void	Signal video source to stop its work.
Start ( ) : void	Start video source. Starts video source and returns execution to caller. Video camera will be started and will provide new video frames through the NewFrame event.
Stop ( ) : void	Stop video source. The method stops the video source, so it no longer provides new video frames and does not consume any resources.
WaitForStop ( ) : void	Wait for video source has stopped.
XimeaVideoSource ( int deviceID ) : System	Initializes a new instance of the XimeaVideoSource class.

SignalToStop() публичный метод

Signal video source to stop its work.

public SignalToStop ( ) : void
Результат	void

Start() публичный метод

Start video source.

Starts video source and returns execution to caller. Video camera will be started and will provide new video frames through the NewFrame event.

There is no XIMEA camera with specified ID connected to the system. An error occurred while communicating with a camera. See error /// message for additional information.

public Start ( ) : void
Результат	void

Stop() публичный метод

Stop video source.

The method stops the video source, so it no longer provides new video frames and does not consume any resources.

public Stop ( ) : void
Результат	void

WaitForStop() публичный метод

Wait for video source has stopped.

public WaitForStop ( ) : void
Результат	void

XimeaVideoSource() публичный метод

Initializes a new instance of the XimeaVideoSource class.

public XimeaVideoSource ( int deviceID ) : System
deviceID	int	XIMEA camera ID (index) to connect to.
Результат	System
