C# Class Accord.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 }

Public Methods

Method Description
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.
