Hello,
I tried to write a small package to subscribe to stereo images of
bumblebee2 and publish them with my own name.
The source code of my source file, (which uses stereo_image_proc) is
attached.
I ran this package like this from the prompt:
shell$ roslaunch bumblebee2 Bumblebee2.launch
shell$ ROS_NAMESPACE=bumblebee2 rosrun stereo_image_proc stereo_image_proc
shell$ rosrun trial1 trial1
(from 'rostopic list -v' i can see the topic "/Yucong/left/image_rect" is
published).
However, after using ' rosrun image_view image_view
image:=/Yucong/left/image_rect '
I see only a window without an image in it.
How can I see the image? Any help would be appreciated, especially since I
am pretty new to the ROS environment.
Thanks,
