ofxCv:Calibration for fisheye produces uneven image
stephanschulz opened this issue · comments
Hi.
For a while now i am trying to do cam calibration with a fisheye lens (150 degree) but get a very messy image.
I tried the chessboard patterns and a assymetricalCircles pattern.
I am using a straight backing for the pattern.
I entered the right square size in the .yml file.
even with a normal lens i see small jumps in straight lines.
what might be wrong with my setup?
turns out setting my logitech c920 to use 640x480 resolution was not a good idea. setting it to 1920x1080 removed the strange edges in the image.
for the fish eye to work i still had to use this code here.
