Dear Agisoft development team,
Especially in very narrow spaces spherical cameras having advantages over frame or fisheye cameras. I have used them to measure vertical channels in old buildings and other narrow spaces. But when you work with spherical cameras, MetaShape have to handle them as ideal cameras, where no camera calibration can be done. Because of their construction they have parallax and therefore issues in stitch zone, which downgrades accuracy and quality of results you can get with them. Some of them save the original fisheye photos as double (or more) fisheye photo. It is possible to split them to single fisheye photos and use them in MetaShape. But because of very small overlap and the missing possibilityto define constrains between a pair of fisheyes you can't align them properly without of the help of the stitched spherical photos.
So my feature request would be:
1) to split to, handle and calibrate left and right fisheyes (in case of double lens spherical cameras) as single cameras groups with their own calibration parameters. (I do that by hand now)
2) For alignment it is needed to define 6, before calculated, constrains, 3 rotations and 3 translations of the second lens in respect to the first lens. This way it is possible to align extracted fisheye photos alone without of the help of the imperfect spherical photos and their stitching errors.
Would be really nice, thanks!
Best regards
Kiesel
