Detailed Description

The Camera class defines a generel interface to a camera. A great deal of the interface resembles the DCAM standard since DCAM allready defines a very wide interface.

typical usage: Camera c; // setup camera features modes and so on c.initialize(); c.start(); // acquire images c.stop();

Constructor & Destructor Documentation

◆ Camera()

Camera	(	const std::string &	name,
		const std::string &	modelInfo
	)

protected

constructor

Parameters

name	[in] name of sensor
modelInfo	[in] info string

Member Function Documentation

◆ addListener()

virtual bool addListener ( CameraListener & listener )

virtual

adds a CameraListener to this camera

Parameters

listener [in] the CameraListener that is to be added

Returns: true if listener was added succesfully, false otherwise

◆ getFrameRate()

virtual double getFrameRate ( )

pure virtual

returns the framerate that this camera is setup with

Returns: the framerate in frames per second

◆ getGain()

virtual double getGain ( ) const

inlinevirtual

Get actual gain value. Note: If gain is not available then a dummy implementation returning -1 is used and an error message is produced.

Returns: Gain value.

◆ getHeight()

virtual unsigned int getHeight ( )

pure virtual

get width of the captured images

Returns: width

◆ getImage()

virtual const Image* getImage ( )

pure virtual

returns the last image acquired from the camera. This method is not blocking, if no image has been acquired yet an empty image is returned. The image returned can for some specific drivers be read only.

Returns: last image captured from camera.

◆ getModelInfo()

virtual std::string getModelInfo ( ) const

inlinevirtual

returns the camera model information (version, type, size, etc.)

Returns: camera model information

◆ getShutter()

virtual double getShutter ( ) const

inlinevirtual

Get actual shutter value. Note: If shutter is not available then a dummy implementation will throw an error message.

Returns: shutter value in micro-seconds.

◆ getShutterBounds()

virtual std::pair<double, double> getShutterBounds ( ) const

inlinevirtual

gets the shutter bounds. Note: If shutter is not available then a dummy implementation will throw an error message.

Returns: first value is the min bound and second value is the max bound

◆ getWidth()

virtual unsigned int getWidth ( )

pure virtual

get width of the captured images

Returns: width

◆ initialize()

virtual bool initialize ( )

pure virtual

initializes the camera to the current settings (CaptureMode,ColorMode,etc.)

Returns: true if initialization is succesfully, false otherwise.

◆ isGainAvailable()

virtual bool isGainAvailable ( ) const

inlinevirtual

Check if gain is available.

Returns: True if zoom is available

◆ isImageReady()

virtual bool isImageReady ( )

pure virtual

tests whether a image has been acquired

Returns: true if an image has been acquired, false otherwise.

◆ isInitialized()

bool isInitialized ( ) const

inline

returns whether this camera is initialized or not.

Returns: true if intialized, false otherwise

◆ isShutterAvailable()

virtual bool isShutterAvailable ( ) const

inlinevirtual

Check if shutter is available.

Returns: True if shutter is available

◆ isStarted()

bool isStarted ( ) const

inline

returns whether this camera is started or not.

Returns: true if started, false otherwise

◆ removeListener()

virtual bool removeListener ( CameraListener & listener )

virtual

removes a CameraListener from this cameras listener list.

Parameters

listener [in] the listener that is to be removed

Returns: true if listener was removed succesfully, false otherwise.

◆ setFrameRate()

virtual void setFrameRate ( double framerate )

pure virtual

sets the framerate of this camera. If the framerate is not supported the closest supported framerate is choosen.

Parameters

framerate [in] the framerate

◆ setGain()

virtual double setGain ( double Value )

inlinevirtual

Set gain value. If the given value is not possible the nearest value are choosen. Note: If gain is not available then a dummy implementation returning -1 is used and an error message is produced.

Parameters

Value New gain value.

Returns: New nearest gain value.

◆ setModelInfo()

void setModelInfo ( const std::string info )

inlineprotected

sets the camera model information

Parameters

info	[in] information of the camera

◆ setShutter()

virtual void setShutter ( double Value )

inlinevirtual

Set shutter value. If the given value is not possible the nearest value are choosen. Note: If shutter is not available then a dummy implementation will throw an error message.

Parameters

Value New shutter value.

◆ start()

virtual bool start ( )

pure virtual

starts this camera, if the camera has not been initialized the initialize function will be called.

Returns: true if camera was successfully started, false otherwise
