<#
C - Width of interpolation band in degrees, must be smaller or equal than FOV "try from 6 to 11 for smoother stitch edge"
FOV - field of view of the fisheye lenses in degrees, "try to play with it from 190 to 199, Be sure to change all 7 of them!"
FOV May not be the same for horizontal(ih_fov) / vertical position(iv_fov)
FOV ARE NOT EQUAL for Left and Right lenses, Left lens capture more info so FOV is less than on the Right lens
For debuging edges use "bgr24" instad of "gray8"
