If your cam driver topics are
/camera/rgb/image_raw
/camera/rgb/camera_info
I guess you should start the image_proc node like:
ROS_NAMESPACE=camera/rgb rosrun image_proc image_proc

If your cam driver topics are
/camera/rgb/image_raw
/camera/rgb/camera_info
I guess you should start the image_proc node like:
ROS_NAMESPACE=camera/rgb rosrun image_proc image_proc
Update with explanations:
The ROS_NAMESPACE=camera/rgb
puts all topics of the node into this namespace. Initially if you run
rosrun image_proc image_proc
it will listen to the topics
/image_raw
/camera_info
. If you than change the call into
ROS_NAMESPACE=camera rosrun image_proc image_proc
as mentioned in the tutorial it will listen to
/camera/image_raw
/camera/camera_info
. However, your camera driver apparently publishes to the /camera/rbg namespace so your call will be
ROS_NAMESPACE=camera/rgb rosrun image_proc image_proc
such that the image_proc node listens to the topics of your camera driver which are:
/camera/rgb/image_raw
/camera/rgb/camera_info
