No Image Recieved Error in rviz [closed]
When I launch rviz using "roslaunch magni_viz view_nav.launch", I get a "Image: warn. No image received" error. My robot's camera is able to detect markers in front of it, so the camera is not the problem. However, no image is displayed on the image tab in the lower left hand corner of rviz. Any help would be greatly appreciated.
