I don't have anything to add on the procedure, but maybe a thing to think about: what do you have from a circular fisheye lens? It may have other purposes, but for Hugin you will probably find it easier with a full frame (field of view, not sensor size) fisheye. I do that on a regular basis, and I don't have to do anything specific (once I have initially told Hugin that it's a fisheye lens, so that it can note it in its database). > Should I only insert the lens specs or I need some other specific > settings (or procedure) in order for Hugin to stitch properly two > images in one equirectangular 360x180 image? Even with the Meike, you won't get that from two images. Assuming that you really get your 190°, that's only horizontally. My program tells me that you won't get that vertically, and you need some overlap: Focal length: 6.50 mm Horizontal FOV: 208.03° Diagonal FOV: 249.86° Vertical FOV: 138.39° Panorama steps (30% overlap): Horizontal: 146° Vertical: 97° The angles beyond 190° are theoretical; that's the part that's blacked out. And the sample images I've seen, such as at https://www.dpreview.com/forums/thread/4121672 , confirm this. It suggests that you'll need at least 6 images to get a full 360x180 panorama. -- Sent from my desktop computer. Finger groog...@gmail.com for PGP public key.
