I have a problem on how to do Kalibr intrinsic calibration w. a long range tele came? focusing at over 70m, HFOV is around 30deg.
Should we build a giant AprilGrid chart and put it from 70m away?
Or add some relay lens or collimator optics equipment? It looks like camera intrinsic parameter will be changed and imprecise.
If anyone has some hint for me, I will appreciate it. Thanks.
