Hi guys i am facing troubles with stitching 360 degrees panorama indoor. Im using Gigapan Pro. My lens is samyang fish-eye 8mm. Overlap set on 75%.  In total i get 40 photos. i have been trying to do it in many ways but it didn't work What would u suggest? thanks in advance

Perhaps the Gigapan Pro doesn't really 'work' for fisheye lenses.

Using a Samyang 8mm Fisheye lens on a cropped sensor DSLR using a manual pano head one would typically shoot one row of 6-around plus zenith and optional nadir; that is with camera/lens in the portrait orientation used by most manual pano heads, rather than the landscape orientation demanded by Gigapan robotic heads.

Since Gigapan robotic heads can only shoot a regular matrix of images (which is a major reason why they are ill suited to shooting spherical panos) then two rows of 6 would be more than enough.

40 images????? That's crazy.

75% overlap is massively too much - anything more than 30% is likely to increase stitching problems.

Thanks for fast reply. Now i set overlap on 30%, but it still doesn't look good =/ now i get 3x3. I just cant get it right. Any ideas how to solve that??

3x3 sound again like an static pattern. that finally gives you on top and bottom region of your pano much higher than 30" overlap.
If I understand gigapan concept correct its not possible to tell the head to take on nadir and zenith region less images and around equator more images.
thats one of your problems causing the errors.
so if you cant do above than you only does have the chance to more images than needed so you finally can skip images you dont use for stitching. the remaining images does still have enough overlap to cover the sphere.

the second is the samyang 8mm. dont knwo if you using a FF or a crop sensor.... with my cropped one the NPP is nearly exact at the outer side of the golden ring located (the side nearer to the glass and farer away from the bajonet of the lens). So 100% check that the samyang 8mm is placed at perfect NPP. test it if needed with shooting from inside through a window outdoors and take some objects outdoors as reference. 1mm out of perfect NPP and you must have parallax errors within 2m range to the lens!!! and indoors this can very fast cause problems...

persoally I placce my equator row of immages some degree up in direction of zenith so I dont need an extra zenitz image. the 6-8 images of the "equator" row cover the zenitz too. Finally I take 1-2 images from nadir. if you've an ballhead below your gigapan you can use this to turn the gigapan and cam mounted (lens showing to equator) to turn the gigapan 90" so lens is directly looking to bottom. Now lift your center pole x cm so the NPP of your lens does have the same height again ...

Im asuming you use your camera in portrait mode - wich does not seem to be the common use with an gigapan...

You can only mount the camera/lens in landscape orientation on Gigpan robotic heads; and you can only shoot a regular matrix of images.

They are really not designed to shoot panos with a 360 HFOV, nor spherical panos.

In my opinion, there is little if any advantage in using a robotic pano head with a fisheye lens, rather than manual pano head, unless you are shooting from a pole.

Thanks for the answers!

Can you tell me which type of distortion I should pick when stitching photos? Im still using samyang fish-eye 8mm

Well - why not try "Fisheye" . .
