kalibr_camera_focus issue

[AntaresZhang]

Using ROS Kinetic on Ubuntu 16.04
Seems like the cv module is no longer used?
i removed
"import cv"
and changed the line
"cv.DestroyAllWindows()" to "cv2.destroyAllWindows()" and it worked fine
i also had to remove the line
"cv2.namedWindow(self.windowNameOrig, 2)"
because other wise the cv window crashes on start up.
after these changes the script worked fine.

Works for me as well in Ubuntu 18.04 ROS melodic.
