Detailed Description

Class for firewire ieee1394 video devices using libdc1394-1.x api.

Deprecated:
This class is deprecated. You shoud use vp1394TwoGrabber class instead.

Needs libraw1394-1.2.0 and libdc1394-1.1.0 or more recent versions available on http://sourceforge.net.

This class was tested with Marlin F033C and F131B cameras. This grabber is not working with a PointGrey DragonFly 2 camera. Since libdc1394-1.x is deprecated, you should better use vp1394TwoGrabber based on libdc1394-2.x.

The code below shows how to use this class.

#include <visp/vpConfig.h>
#include <visp/vpImage.h>
#include <visp/vpImageIo.h>
#include <visp/vp1394Grabber.h>
int main()
{
#if defined(VISP_HAVE_DC1394_1)
vpImage<unsigned char> I; // Create a gray level image container
vp1394Grabber g; // Create a grabber based on libdc1394-1.x third party lib
g.setFormat(FORMAT_VGA_NONCOMPRESSED); // Format_0
g.setMode(MODE_640x480_MONO); // Mode 5
g.setFramerate(FRAMERATE_15); // 15 fps
g.open(I); // Open the framegrabber
g.acquire(I); // Acquire an image
vpImageIo::writePGM(I, "image.pgm"); // Write image on the disk
#endif
}

Constructor & Destructor Documentation

vp1394Grabber::vp1394Grabber ( )
Deprecated:
This class is deprecated. You shoud use vp1394TwoGrabber class instead.

Default constructor. Using this constructor, you have explicitly to call open().

By default:

  • the camera is the first found on the bus,

Current camera settings can be changed using setCamera(), setFormat(), setMode() or setFramerate() after a call to open(). The list of supported formats, modes and framerates is available using respectively getFormatSupported(), getModeSupported(), getFramerateSupported().

g.open(I);
g.setFormat(FORMAT_VGA_NONCOMPRESSED); // Format_0
g.setMode(MODE_640x480_MONO); // Mode 5
g.setFramerate(FRAMERATE_15); // 15 fps
