Hi everyone
I have a system that have a camera in a distance of about 60cm from object, and the FOV is a rectangle with about 50cm*60cm dimensions. because of this big FOV I had to use a lens with 5mm focal length. with this lens I have about 7% of error in the corners of the image because of the lens distortion. and when I use the Distortion Model(Grid) calibration step in Vision Assistant , the 7% error exists again.
please let me know if there is a tip in setting or anything else that would help..
this is my main picture:
and this is the corrected image after calibration process:
thank you in advance
best regards, Eric
