The roslaunch fails with the "process died"

[ashnarayan13]

I am running two pointgrey flea3 cams and tried running the stereo_sim.launch file. I get a process died for the camera nodes.
Even the stereo.launch fails

The problem is probably in the ".npy" camera parameters files. This message is for the stereo.launch or for the stereo_sim.launch?

If you have the rectified image topics from your camera you cam run only the stereo_node. (just make sure the topics name are correct).

The rectification procedure i'm using is really bad so i will try to change it as soon as possible.

I get this message for both the launch files. I have rectified images, I just want to test the real time stereo matching

[rachillesf]

if your images are rectified you can just run the stereo_node. Only make sure the name of your topics are correct.

I ran just the stereo_node with rectified images, I get nothing on the camera/depth/pointcloud and camera/depth/image although I am running the bag file and set the appropriate topic names.
The rqt_graph shows only subscription to only 1 of the cameras and not the stereo.
Any reason for this to happen? Thanks
