"File write Failed" Error on calibration commit

[Former user]

Version

0.0.10 (2016-07-12)

Steps to reproduce

• run ROS kinetic on Ubuntu 16.04 in a Virtual Box.
• Use the UEye-node to publish the raw images (remapped raw_image and service or not)
• Then start the camera_calibration node and do the calibration until calibrate button activates.
• (Saving the Output to /tmp/calibrationdata.tar.gz' works fine.)
• pressing the commit-button will throw the error.

Thank you for the bug report.

If not specified, the directory to load/save calibration files defaults to the path to the ueye package. If installed to /opt/ros with apt-get, the directory is read-only. Try changing the config_path parameter to a directory with write privileges.

Hello, I installed the ueye driver today. According to the instructions on the wiki, after running rosrun ueye stereo, you can see that the camera has started to collect, and there is also a news release, but the rviz tool displays no images received, and the rqt tool does not Display image; rosrun image_view will be stuck when viewing a camera image alone, no image will appear!

@hi_coder please create a new issue because your problem is separate from this "Error on calibration commit" issue.

Do your cameras work individually with rosrun ueye camera? Do your cameras work with the other ueye_cam ROS driver?

Hi Kevin,

I am facing the same error. I tried the config_path parameter and used to set to a directory with write access but no good. Also, I am able to commit the calibration when calibrating my webcam and another usb_cam, but am unable to commit the ids camera that I running through the ueye camera node. Could you please help me with this. Thank you
