problem on running image_view node
Hi all, I installed the package ros-groovy-camera-umd, after this I run a launch file like this
<launch>
<node ns="camera" pkg="uvc_camera" type="camera_node" name="uvc_camera" output="screen">
<param name="width" type="int" value="640" />
<param name="height" type="int" value="480" />
<param name="fps" type="int" value="30" />
<param name="frame" type="string" value="webcam" />
<param name="device" type="string" value="/dev/video0" />
</node>
</launch>
The device path I have already checked where it is connected and if the camera is responding.
After running the launch file I get this response:
unable to open camera calibration file ["path"/camera.yml]
Camera calibration file "path"/camera.yml not found
I only handle discrete frame intervals…
I only handle discrete frame intervals…
I only handle discrete frame intervals…

Then I try to look at the topic /camera/image_raw
rosrun image_view image_view image:=/camera/image_raw
And I get no response from the camera
