pointgrey_camera_driver not publishing data to /camera/raw_image topic
I'm brand new to ROS, using Jade on Ubuntu 14.04 on x86 with kernel 3.13.0. I have a pointgrey flea3 installed and I can see it listed when I run
$ rosrun pointgrey_camera_driver list_cameras
and when I run
$ rosrun pointgrey_camera_driver camera.launch camera_serial:=14386092
$ rostopic list
I get the following
/camera/camera_info

/camera/camera_nodelet_manager/bond

If I try to run
$ rosrun image_view image_view image:=/camera/image_raw
I get an empty window, and when I right click on the window, I get
[ WARN] [1463431322.944317447]: Couldn't save image, no data!
If I point rqt_image_view to the /camera/image_raw topic, the window is also blank. I can get video via pointgrey's flycap utility, so I know the camera is working. What am I missing?
Thanks!
Did you go through the UDEV config steps?
I've only used the point grey driver to get the camera serial # and to ensure it's properly connected to the computer. I use the camera1394 node to stream the images and camera configuration.
Hi, I am facing the same issue. Can you share the solution if you got it working?
Hi @Sam6, have you tried to do 'rostopic echo /camera/image_raw'? Does that give you any information?
@rsmitha Hey, thanks for asking. But I got that problem resolved. I was just doing a silly mistake of giving wrong arguments to the image_view command.
@Sam6 what is the correct command? could you share? Thanks
