Hi, I am sorry about my last message I know I wasn't as much specific as I  
should be, now I will try to explain it better.

We have the bumbblebee XB3 BBX3-13S2C connected by firewire on a debian  
squeeze box with ros installed using diamondback. I would like to obtain 3D  
information (point cloud, stereo image and disparity map) using this  
camera .


I have seen that the package ''bumblebee2'' provides the left and rigth  
images and the disparity image, and the "bumblebee_stereo" package computes  
disparity and point cloud from a pair of stereo images so I have tried them  
both.

when I use coriander it works correctly. I have also installed camera1394  
package, I type rosrun camera1394 camera1394_node and in other console I  
type rosrun image_view image_view image:=camera/image_mono and it shows a  
mono image obtained by the cam.

Everything is going ok until this moment, but the problems start when I try  
the next packages:



bumblebee2 package
I type roslaunch bumblebee2 Bumblebee2.launch and I obtain this:

[error][1310052718.389426286]:segmentation fault, stopping camera.
segmentation fault stopping camera driver.

but this error appears several times and does not stop by itself



bumblebee_stereo package
by the other side I have installed the bumblebee_stereo package but when I  
type roslaunch bumblebee_stereo bumblebee_stereo.launch I obtain this:

Do I have forgotten something that makes that the packages don't work?
what can i do?

Thanks in advance.
