void UFunctionCamBase::createResources ( )

virtual

Create any resources that this modules needs and add these to the resource pool to be integrated in the global variable pool and method sharing.

Reimplemented from UFunctionBase.

Reimplemented in UFuncV4lGst, and UFunctionCamGmk.

References UFunctionBase::addResource(), camPool, UFunctionBase::createResources(), and UCamPool::findDevices().

UCamPush * UFunctionCamBase::getCam	(	int	imgDevice,
		const char *	posName
	)

protected

Get camera pointer form either a device number or a device position name.
If 'imgDevice' is >=0 then this value is used to get a device. if not,
then if 'posName' has a length > 0 the camera is found from this name,
if imgDevice < 0 and posName is empty, then device 0 is returned (and may be invalid (NULL).
Returns the requested camera or NULL.

References camPool, UCamPool::getCam(), and UCamPool::makeDevice().

Referenced by getCamAndRawImage(), UFuncBall::handleCommand(), UFuncImgPoly::handleImgPolyCommand(), and UFunctionCamPath::handlePathGetCommand().

UCamPush * UFunctionCamBase::getCam ( int camDevNum )

protected

Get camera device pointer.

Parameters

camDevNum is the camera device number

Returns: NULL if device do'nt exist or a pointer to the requested camera device

References camPool, and UCamPool::getCam().

bool UFunctionCamBase::getCamAndRawImage	(	UCamPush **	cam,
		UImage **	imgRaw,
		int *	imgDevice,
		void *	imgBase,
		const char *	posName,
		int	rectfiedImg
	)

protected

Get a camera and an image reference from this set of parameters. The camera is returned in 'cam'.
The image (raw only) is returned in 'img', if img is NULL, then imagepool img 0 is allocated.
The image device (often corresponding to /dev/videoX number) should be set in 'imgDevice' if unknown, then set to -1 on call.
'imgDevice' is set on exit if -1 before call.
'imgRemRad' should be set to as appropiate, but is valid if image is captured from camera directly, otherwise the value is set from image on return.
the 'imgBase' pointer may point to a (pushed) image or may be NULL. If null, then an image is taken from camera.
The camera may be selected from a position name 'posName' as an alternative to a device number.

Parameters

rectfiedImg is a number in image-pool where the rectified image are placed if the number is not a valid image pool number (i.e. -1) then no rectified image is produced. It further requires that the rectification parameters are set. true if an image is available. NB! a camera may not be available, if the device from image-descriptor is invalid, and in such cases the 'cam' will be returned as NULL.
