Description

The operator open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber opens and configures the chosen image acquisition device. During this process, the connection to the image acquisition device is tested, the image acquisition device is locked for other processes, and, if necessary, memory is reserved for the data buffers. The actual image grabbing is done via the operators grab_imagegrab_imageGrabImageGrabImageGrabImage, grab_datagrab_dataGrabDataGrabDataGrabData, grab_image_asyncgrab_image_asyncGrabImageAsyncGrabImageAsyncGrabImageAsync, or grab_data_asyncgrab_data_asyncGrabDataAsyncGrabDataAsyncGrabDataAsync. If the image acquisition device is not needed anymore, it should be closed via the operator close_framegrabberclose_framegrabberCloseFramegrabberCloseFramegrabberCloseFramegrabber, releasing it for other processes. Some image acquisition devices allow to open several instances of the same image acquisition device class.

For all parameters image acquisition device-specific default values can be chosen explicitly (see the parameter description below). Additional information for a specific image acquisition device is available via info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberInfoFramegrabber. A comprehensive documentation of all image acquistion device-specific parameters can be found in the corresponding interface documentation in the directory 'doc/html/reference/acquisition'"doc/html/reference/acquisition""doc/html/reference/acquisition""doc/html/reference/acquisition""doc/html/reference/acquisition".

The meaning of the particular parameters is as follows:

HorizontalResolution, VerticalResolution

Desired resolution of the image acquisition device.

ImageWidth, ImageHeight

Size of the image part to be returned by grab_imagegrab_imageGrabImageGrabImageGrabImage etc.

StartRow, StartColumn

Upper left corner of the desired image area.

Field

Desired half image ('first', 'second', or 'next') or selection of a full image.

BitsPerChannel

Number of bits, which are transferred from the image acquisition device per pixel and image channel (typically 5, 8, 10, 12, or 16).

ColorSpace

Output color format of the grabbed images (typically 'gray' or 'raw' for single-channel or 'rgb' or 'yuv' for three-channel images).

Generic

Generic parameter with device-specific meaning which can be queried by info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberInfoFramegrabber.

ExternalTrigger

Activation of external triggering (if available).

CameraType

More detailed specification of the desired image acquistion device (typically the type of the analog video format or the name of the desired camera configuration file).

Device

Device name of the image acquistion device.

Port

Port the image acquistion device is connected to.

LineIn

Camera input line of multiplexer (if available).

The operator open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber returns a handle (AcqHandleAcqHandleAcqHandleAcqHandleacqHandle) to the opened image acquisition device.

Attention

Due to the multitude of supported image acquisition devices, open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber contains a large number of parameters. However, not all parameters are needed for a specific image acquisition device.

For a multithreaded application all image acquisition operators, i.e., info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberInfoFramegrabber, open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber, get_framegrabber_paramget_framegrabber_paramGetFramegrabberParamGetFramegrabberParamGetFramegrabberParam, set_framegrabber_paramset_framegrabber_paramSetFramegrabberParamSetFramegrabberParamSetFramegrabberParam, get_framegrabber_callbackget_framegrabber_callbackGetFramegrabberCallbackGetFramegrabberCallbackGetFramegrabberCallback, set_framegrabber_callbackset_framegrabber_callbackSetFramegrabberCallbackSetFramegrabberCallbackSetFramegrabberCallback, get_framegrabber_lutget_framegrabber_lutGetFramegrabberLutGetFramegrabberLutGetFramegrabberLut, set_framegrabber_lutset_framegrabber_lutSetFramegrabberLutSetFramegrabberLutSetFramegrabberLut, grab_image_startgrab_image_startGrabImageStartGrabImageStartGrabImageStart, grab_imagegrab_imageGrabImageGrabImageGrabImage, grab_image_asyncgrab_image_asyncGrabImageAsyncGrabImageAsyncGrabImageAsync, grab_datagrab_dataGrabDataGrabDataGrabData, grab_data_asyncgrab_data_asyncGrabDataAsyncGrabDataAsyncGrabDataAsync, close_framegrabberclose_framegrabberCloseFramegrabberCloseFramegrabberCloseFramegrabber and close_all_framegrabbersclose_all_framegrabbersCloseAllFramegrabbersCloseAllFramegrabbersCloseAllFramegrabbers are an own group in which info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberInfoFramegrabber, open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber, close_framegrabberclose_framegrabberCloseFramegrabberCloseFramegrabberCloseFramegrabber and close_all_framegrabbersclose_all_framegrabbersCloseAllFramegrabbersCloseAllFramegrabbersCloseAllFramegrabbers are executed exclusively.

Thus, info_framegrabberinfo_framegrabberInfoFramegrabberInfoFramegrabberInfoFramegrabber, open_framegrabberopen_framegrabberOpenFramegrabberOpenFramegrabberOpenFramegrabber, close_framegrabberclose_framegrabberCloseFramegrabberCloseFramegrabberCloseFramegrabber and close_all_framegrabbersclose_all_framegrabbersCloseAllFramegrabbersCloseAllFramegrabbersCloseAllFramegrabbers block the concurrent execution of all other operators within this group, but run in parallel with all non-exclusive operators outside of this group.

On Windows Systems, error dialog boxes from the operating system can occur when dependency modules of the interface are not found, e.g., the according SDK was not installed. The occurrence of the error boxes can be controlled by setting Windows' Error Mode. Please refer to the description of SetErrorMode within the Windows MSDN documentation.

Execution Information

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
