I'm an APP newbie, still experimenting with trial version. I'm highly impressed by what I've seen. Been doing fairly low quality virtual tours for some time now with rather old school equipment... Nikon 995 and FC-E8 fisheye converter. I'm guessing that to move up to producing tours like I've seen here I'll need to step up with new equipment. But as an experiment I've been attempting to use some of my past tour photos with APP. The photos I'm using are circular fisheyes jpgs, 2 shots only per pano since the FC-E8 provides a 183 degree image (full circle photo with black rectangular border if you aren't familiar with this type of output). I did see on the APP Fisheye Video Tutorial that it was possible to use 3 circular fisheyes. When I attempt to render 2, basically nothing happens. APP says 'no panorama found'. I have played arround with various settings: advanced distortion, high detection, increased key points, made sure fisheye and circles were set. Would not render. I then tried 'force every image' which created a pano, but basically layered one circular fisheye atop the other. Is is possible to create a pano with only 2 circular fisheyes? My guess is that 2 circular fisheyes with only 3 degrees of overlap is too little for APP to work with. Any suggestions gratefully appreciated. I do plan to move to a more up-to-date set-up, as I am so impressed by the quality I've found it the gallery. Kudos to all the photographers here. Nice work!. But was wondering if what I've tried... just using 2 fisheye shots... is in fact possible with APP. Thanks.
I used a Coolpix 995 with FC-E8 for spherical panos, but, as far as I remember, I always used the fisheye option in the Lens camera menu which causes the whole rectangular image area being used, not the smaller circular image which cover 183° in every directions. In this "rectangular" or "full frame fisheye" mode, no less than 6 images are needed to cover the sphere and shooting 5 or 6 of them along the horizon plus one for the zenith and one for nadir makes things much easier... (and results in a much more crisp stitched pano.)
To stitch a full pano from only two circular fisheye images using Autopano, I would try to use the Move tool (to be found in the panorama editor) but if the corresponding images were precious ones I would rather use one of the PanoTools stitchers like Hugin or PTgui where, hopefully, it would be possible to place some control points "by hand".
If you can use the last Autopano Giga version (APG V1.9.1 alpha 2) with the GPU option enabled this should help a lot: using the Move tool to change yaw, pitch and roll values for a source image (in large or very small steps, leaving the other one unchanged) would be a lot faster and easier.
