[ros-users] camera_info message and stereo_image_proc

Firstly for Rosen on /stereo/[left|right]/camera_info:
In my case, i.e. after running:
"roslaunch videre_stereo_cam  videre.launch"
"rosrun stereo_image_proc stereo_image_proc stereo:=stereo image:=image_raw"
if I run e.g. "rostopic info /stereo/left/camera_info"
I am getting following:
Type: sensor_msgs/CameraInfo

 * /stereo/stereodcam (

Subscribers: None
So camera_info is being published by the stereodcam (and not by e.g.
/stereo/stereo_image_proc) node which I think is a desired behavior.

Secondly, response to myself:
> @Rosen: Out of curiosity, running videre.launch file from

This got magically (I swear:-)) better and now I am getting 30fps.

Thirdly, on getting color images:
I am still getting no color images.
After running "rosrun image_view stereo_view stereo:=stereo image:=image_color"
I seem to be getting image_raw displayed. Do I need to do something
special for color images?
cheers, D.
