Correct. There are still some problems with the CameraInfo file handling I have not had time to fix. It does not handle empty files gracefully. I need to open a problem ticket on that. The easiest calibration technique is probably to run without setting ~camera_info_manager/url. That causes the calibration file to be written in /tmp. Then, copy that file to your camera data directory and point the URL parameter where you just put it. -- joq
