Hi. I am using the camera1394 to interface my stereo camera, but seem to have some issues with passing my two yaml files consisting of the calibration of left and right image frame.

it seem to be possible within the launch file stereo_camera_full.launch to pass the path for both files, but the output image isn't getting rectified. What could be wrong?

The yaml for the left camera looks like this

image_width: 1024
image_height: 768
camera_name: 00b09d010081dfed_left
camera_matrix:

Are you using camera1394 or camera1394stereo? Where did you find stereo_camera_full.launch?

That package is different from camera1394, so I added that tag to your question. Hopefully, those maintainers will see it now.

it's right, to get rectified image you should run the stereo_image_proc node.The stereo_camera_full.launch just publish the yaml file.
