Detailed Description

template<typename T>
class mimas::image_dc1394input< T >

Image input from firewire digital camera (video1394).

At the moment only grabbing of grayscale and YUV422-encoded images is supported. Grabbing has been tested with the following device:

Basler A302fc

See Ryutaroh Matsumoto's page for more information.

Here is an example on how to use this class:

#include <fstream>
#include <GL/glut.h>
#include "image_dc1394input.h"
#include "image_mesaoutput.h"

using namespace std;
using namespace mimas;

// Minimal program for displaying multiple images from a single file.
int main( int argc, char *argv[] )
{
  int retVal = 0;

  try {

    // Initialise GLUT.
    glutInit( &argc, argv );
    
    // Open X11 display.
    x11_display disp;

    // Load file.
    image_dc1394input< rgba< unsigned char > >
      input( MODE_640x480_YUV422, FRAMERATE_15 );
    
    // Open window.
    image_mesaoutput< rgba< unsigned char > > win( &disp );

    // Allocate image.
    image< rgba< unsigned char > > img;

    while( input ) {
      
      // Read image.
      input >> img;

      // Display image.
      win << img;

    };

  } catch ( exception &e ) {

    // Print error message.
    cerr << e.what() << endl;
    retVal = 1;

  };
  
  return retVal;
}

Constructor & Destructor Documentation

template<typename T>

mimas::image_dc1394input< T >::image_dc1394input	(	int	_mode,
		int	_framerate = `FRAMERATE_15`,
		int	_node = `0`,
		const char *	_device = `NULL`,
		int	_channel = `0`,
		int	_speed = `SPEED_400`
	)			throw (mimasexception)

Constructor.

At the moment, there is no support to get a list of available modes or automatically select the best mode. You need to use f.e. the software `coriander', if you want to know the capabilities of the camera.
