Hello,
i updated 3 computers with the last photoscan software. Since than photoscan is significant slower.
Same camera nearly same number of photos. Mostly for dense cloud calculation.
Is this normal?

Camera Calibration / Negativ Focal Lengt - Fisheye
« on: March 05, 2017, 03:29:12 PM »
Hello,
i am playing with Camera Calibration and iam not shure if the calibration is correct.
I tried a gopro hero 4 silver and a xiaomi yi 2k with different photo sets (5-60) and i always get an negativ focal lenght.
Is this normal for an fisheye camera?

And my second question xiaomi yi offers a "Lens Rectification" mode, which turns off the fisheye effect.
If i use this mode should i use frame or fisheye mode? I am not sure because there is also a light fisheye effect left.
I attached one calibration photo with fisheye off.

Thanks for support
Sven
