Focal Point X and Y
« on: April 26, 2023, 05:52:15 PM »
Hello,
I have some calibration data about a lens, but I can't find a way to specify Fx and Fy, there is a single F available.

hi tazzo,

using B1 affinity coefficient of Agisoft calibration, the relationship between f, fx and fy is following:
Code: [Select]
fy = f
fx = f + B1

Hope this is useful,
Best Regards,
