Hey there, will imperfect planar target lead to an issue like that?

We use a chessboard printed by A1 paper

Hi, this project uses the same camera model as OpenCV and shares as much code as possible. The only difference is the optimization process which release the chessboard's coordinates too (for the fact the checkerboard is not precisely machined).

The new calibration method was not tested with wide-angular cameras because the camera model might be not fit them.

If interested, you can ran some test with the example code from OpenCV with your images feed-in.
