Revision history [back]

The error seems to be caused by camera_calibration_parsers::writeCalibration(<dest yaml="" file="">, <cam name="">, <calib data="">), as seen in ueye_cam/src/ueye_cam_nodelet.cpp, UEyeCamNodelet::saveIntrinsicsFile().

I suspect that there is some write-permission issues / out-of-space issues with /home/rospasta/.ros/camera_info/. Please test and confirm.
