Detailed Description

Class for firewire ieee1394 video devices using libdc1394-2.x api.

Needs libraw1394-1.2.0 and libdc1394-2.0.0 or more recent versions available on http://sourceforge.net.

This class was tested with Marlin F033C and F131B cameras and with Point Grey Dragonfly 2, Flea 2 and Flea 3 cameras.

This grabber allows single or multi camera acquisition.

  • Here you will find an example of single capture from the first camera found on the bus. This example is available in tutorial-grabber-1394.cpp:

Constructor & Destructor Documentation

◆ vp1394TwoGrabber()

vp1394TwoGrabber::vp1394TwoGrabber ( bool  reset = true)

Default constructor.

By default:

  • the camera is the first found on the bus,
  • the ring buffer size is set to 4,
  • reset the bus attached to the first camera found on the bus.

Current camera settings can be changed using setCamera() to select the active camera on the bus and than setVideoMode() or setFramerate() to fix the active camera settings. The list of supported video modes and framerates is available using respectively getVideoModeSupported() and getFramerateSupported(). To change the ring buffer size use setRingBufferSize().

Parameters
reset: If "true", reset the bus attached to the first camera found. Bus reset may help to make firewire working if the program was not properly stopped by a CTRL-C.

Below you will find an example that shows how to grab images in Format7 with a transmission speed set to 800Mbps in 1394b mode.

#include <visp3/core/vpImage.h>
#include <visp3/sensor/vp1394TwoGrabber.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
int main()
{
#if defined(VISP_HAVE_DC1394)
vpImage<unsigned char> I;
vp1394TwoGrabber g(false); // Don't reset the bus
g.setVideoMode(vp1394TwoGrabber::vpVIDEO_MODE_FORMAT7_0 );
g.setColorCoding(vp1394TwoGrabber::vpCOLOR_CODING_MONO8);
g.setAutoShutter(1600*20-1, 1600*20); // Set shutter min and max values
g.setIsoTransmissionSpeed(vp1394TwoGrabber::vpISO_SPEED_800); // 1394b
while(1)
g.acquire(I);
#endif

◆ resetBus()

void vp1394TwoGrabber::resetBus ( )

Resets the IEEE1394 bus which camera is attached to. Calling this function is "rude" to other devices because it causes them to re-enumerate on the bus and may cause a temporary disruption in their current activities. Thus, use it sparingly. Its primary use is if a program shuts down uncleanly and needs to free leftover ISO channels or bandwidth. A bus reset will free those things as a side effect.

The example below shows how to reset the bus attached to the last camera found.

#include <visp3/core/vpImage.h>
#include <visp3/sensor/vp1394TwoGrabber.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
int main()
{
#if defined(VISP_HAVE_DC1394)
unsigned int ncameras; // Number of cameras on the bus
vp1394TwoGrabber g;
ncameras = g.getNumCameras();
g.setCamera(ncameras-1); // To dial with the last camera on the bus
g.resetBus(); // Reset the bus attached to "ncameras-1"

◆ setCamera()

void vp1394TwoGrabber::setCamera ( uint64_t  cam_id)

If multiples cameras are connected on the bus, select the camero to dial with.

Parameters
cam_id: A camera identifier or GUID. By identifier, we mean a value comprised between 0 (the first camera found on the bus) and the number of cameras found on the bus and returned by getNumCameras() minus 1. If two cameras are connected on the bus, setting camera_id to one allows to communicate with the second one. This identifier is not unique. That is why, it is also possible to select a camera by its GUID, which is unique.
Exceptions
vpFrameGrabberException::settingError: If the required camera is not reachable.

void acquire(vpImage< unsigned char > &I)
Definition: vp1394TwoGrabber.cpp:2561

If more than one camera is connected, it is also possible to select a specific camera by its GUID:

#include <visp3/core/vpImage.h>
#include <visp3/io/vpImageIo.h>
#include <visp3/sensor/vp1394TwoGrabber.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
int main()
{
#if defined(VISP_HAVE_DC1394)
vpImage<unsigned char> I; // Create a gray level image container
bool reset = false; // Disable bus reset during construction
vp1394TwoGrabber g(reset); // Create a grabber based on libdc1394-2.x third party lib
unsigned int ncameras; // Number of cameras on the bus
ncameras = g.getNumCameras();
std::cout << ncameras << " cameras found:" << std::endl;
for(int i=0; i< ncameras; i++)
{
g.setCamera(i);
uint64_t guid = g.getGuid();
printf("camera %d with guid 0x%lx\n", i, guid);
}
// produce:
// 2 cameras found:
// camera 0 with guid 0xb09d01009b329c
// camera 1 with guid 0xb09d01007e0ee7
g.setCamera( 0xb09d01009b329c );
printf("Use camera with GUID: 0x%lx\n", g.getGuid());
g.acquire(I); // Acquire an image from the camera with GUID 0xb09d01009b329c
vpImageIo::write(I, "image.pgm"); // Write image on the disk
#endif
}

Here an example of multi camera capture:

#include <visp3/core/vpImage.h>
#include <visp3/sensor/vp1394TwoGrabber.h>
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;

unsigned int ncameras; // Number of cameras on the bus
vp1394TwoGrabber g;
ncameras = g.getNumCameras();
vpImage<unsigned char> *I = new vpImage<unsigned char> [ncameras];
// If the first camera supports vpVIDEO_MODE_640x480_YUV422 video mode
g.setCamera(0);
g.setVideoMode(vp1394TwoGrabber::vpVIDEO_MODE_640x480_YUV422);
if (ncameras >= 2) {

g.setCamera(camera);
g.acquire(I[camera]);
}

◆ setPanControl()

void vp1394TwoGrabber::setPanControl ( unsigned int  panControlValue)

This method is useful for controlling single or multiple image transmission from stereo vision cameras.

The PAN register 0x884 used to control which images are transmitted is set to the corresponding panControlValue value.

Parameters
panControlValue: Value used to set the PAN register 0x884. The Format_7 Mode 0 transmits images from one camera. When set to 0, transmit right image. When set to 1, transmit left (Bumblebee2) or center (Bumblebee XB3) image and when set to 2 or higher transmit left image. The Format_7 Mode 3 allows to transmit two images simultaneously. If your camera has two sensors, you can use the PAN register to control the order of the images when transmitting. Writing a value of 0 to this register transmits images in right-left format. A value of 1 transmits images in left-right format. If your camera has three sensors, such as the Bumblebee XB3, you can adjust the PAN register as follows to specify which two sensors are capturing images. When panControlValue is set to 0, transmit right-left images, when set to 1, transmit right-center images.
Exceptions
vpFrameGrabberException::initializationError: If no camera found on the bus.
vpFrameGrabberException::settingError: If the register was not set.

◆ setParameterValue()

void vp1394TwoGrabber::setParameterValue ( vp1394TwoParametersType  param,
unsigned int  val 
)

This method set the value of one of the parameters of the camera. The initial value of the parameter is recorded and reset when the destructor is called.

Warning
If the program crashes and the destructor is not called, then the modified parameters will remain in the camera.
Parameters
param: The parameters to modify
val: the new value of this parameter
Exceptions
vpFrameGrabberException::initializationError: If no camera found on the bus.
