Note:
We
have
passed
camera.node
which
indicates
that
the
dc1394_cameracapture structure is being used and only the particular node
for which the camera has been setup is being referred to.
But we can as well use camera_nodes[0].
8. Have the camera start sending the data to the user. This is done by
starting the iso transmission. The following function is used
dc1394_start_iso_transmission(handle,camera.node)
9. Capture one frame by calling the function
dc1394_single_capture(handle,&camera)
camera is a pointer to the structure dc1394_cameracapture. This function
will grab the image and store it in the buffer (capture_buffer) provided by
the structure.
In order to capture more than one frame use a for loop and place the
function inside it
for( i=0;i<100 ;i++)/* to capture 100 images*/
dc1394_single_capture(handle,&camera)
10. After the image has been grabbed, stop the data transmission by calling
the following function
dc1394_stop_iso_transmission(handle,camera.node)
11. Add a PGM file header to the captured buffer to see the image using
gimp.
12.
Use
fwrite
to
save
the
captured
image,
by
writing
the
buffer(camera.capture_buffer) in a file. The other parameters like height
and width of the image can be extracted from the same structure:
camera.frame_width, camera.frame_height.
13. Close the camera. This step is necessary to save from the memory leak.
