Undistort cameraParameter file

Dear all,

I have some problem using the undistort node, because i can not find the cameraparameter file .txt

I already use the undistort node 2 years ago and i remember that it was unusable untill when you don’t connect the cameraParameter file in the right place… i remember that at that time i used a .txt file which was from another camera… not sure, but seams me a logitech… and it was working. offcourse because I’m completly messy i can not found it again.

do you have any solution

thank you all
