My fisheye camera came with XDV360 software, which converts in real time both images and videos from fisheye to "cropped equirectangular", i.e. shows only a small portion of the full dome (to be viewed with Head Mounted display).
But I think the SW is designed for fisheye cameras with 180° FOV or less, but mine has 235° FOV (actually seeing behind itself!), thus resulting in images squeezed in height.
I'd need a SW which allows customizing the FOV before reprojecting.
Any suggestion?
