hi all, i'm trying to display a camera on rviz, the source is a camera on Gazebo. rviz shows me that:

CameraInfo -> No CameraInfo received on [/finger_tip_cam/camera_info]. Topic may not exist.

image -> No image received.

Transform [sender/=Gazebo] -> No CameraInfo received on [/finger_tip_cam/camera_info]. Topic may not exist.

What could the problem be?

Try running "rostopic list", and adding an (edited) list of the relevant topics to your question.

Instead of adding a camera in rviz, try adding an image. If the publisher of this topic only updates the image and not all the information required for a ROS camera interface, rviz can not display the image.

What other information is required for a ROS camera interface?

Make sure the camera <framename> is correct in the <plugin name="camera_controller" filename="libgazebo_ros_camera.so"> section of the urdf. I had mine set to camera_link and was getting the same error because camera_link wasn't a real link (and I had cut and paste it from a gazebo camera example). The camera view shown isn't the same as the raw image rqt_image_view or the rviz image display (as Mani suggests above and probably what you wanted anyhow), it tries to overlay elements of rviz onto the view.

I'm having that problem. What name did you use for the <framename> to solve it?
