General / Re: Circular Fisheye Workflow...

Hi Alexey,
Thanks for the quick reply. I should say my name is Chris, nice to meet you!!
I have to crop / split the original images as they come as two side by side circular panorama in a single RAW file. During the split i remove the unused black space at the edges and mask out the circle.
My tests so far using a left + right hemisphere split (only standard version for me) were successful, however I try to keep the yaw / bearing / orientation consistent between images as I move.
I assume that if I were to rotate 90 degrees between image pairs (so that a feature that was in the centre of the fisheye is now at the edge) then association would fail due to high distortion even though the actual motion is small. If that is true I could try to unwrap the image pair into a rectilinear view first to help.
I have a background in robotics so could do unwrap in openCV, just don’t want to try if the idea is silly...
Thanks,
Chris
