DJI Ronin 360 Pano feature

[MarkL]

Hello all, 

Just getting into doing 360 panos, a project at work lead me to creating some full 360 panos of rooms at work for web use. 

I have a DJI RS3 gimbal (with a pano mode) and a 20mm on my A7 IV and I used that to take the photos, due to how you have to balance the gimbal, it's basically impossible to get it "parallax free". 

Using 30% overlap the results are pretty good but there's a lot of small stitching errors, some far some close to the camera. I have spent some time adding or deleting control points and I doesn't seem to help that much. And I get pretty large errors "average 20px max 85". Attached a low-res version of the result. 

Is there much I can do to fix these errors? Or is the solution just to get a real pano head and dial out parallax. Some of the errors seem like something software could correct for but buying a new head is something I rather do then spend hours fixing each one. 

Thanks for any input.

Hi Mark,

Using PTGui Pro might help to some extent, it has a 'find optimum seams'
feature. It could hide some of the misalignments in the panorama.

But generally these indoors panoramas will be hopeless; you'll spend
hours trying to fix it but it will never be perfect. I would get a
panoramic head.

Also, unless you need super high resolution, consider getting a 12 or
15mm fisheye lens. You'll have fewer images to stitch, and you will no
longer have images containing only a pure white wall or ceiling.

Kind regards,

Thank you for the info, I used PTGUI 12 pro trial and didn't realize it had that feature, Explains some of the differences I see. 
But I have the pano head on order. 

Thanks

Follow up question on this is there a way to move the seams manually in non-pro PTGUI? 

Thanks.

Mark, there is no way to move the seams interactively in the standard version of PTGui.  However, it is possible to have some control via image masks created in Photoshop using an alpha channel.  The masks so created would be similar in effect to the red masks in the Pro version.  You can open an image file simultaneously in Photoshop, and updates to the alpha channel mask will be seen in PTGui on saving the file in Photoshop.  I wrote a tutorial for doing this a long time ago in 2008, and it still works despite its rather ancient appearance:   HOW TO USE AN ALPHA CHANNEL TO MASK OUT AREAS OF AN IMAGE (johnhpanos.com)
