Question

Mavic 3 Classic panorama images unable to stitch in Lightroom 12.0.1

I shot panorama images in RAW (9 images total)  with the new Mavic 3 Classic and I'm unable to stitch them with the perspective mode in Lightroom 12.0.1. 

 

Prior to this I used Mavic 2 and didn't have any issues with this. 

 

Does somebody experience similar issues?

having the same issue with a mavic 3 cone. the problem is the new panorama 3x3 mode from the mavic. dji says its a feature... and they dont want to change it. the gimbal rotates when capturing the panorama - every row has a different horizon-line. its terrible

I'm surprised nobody else has encountered this issue when most professional use this feature to generate panoramas from the DNG. I was told that the issue is that the new Classic lens is now 24mm, the previous Mavic 2 is 28mm. The stitching of perspective mode is only good at 25mm and above, 24mm is too wide.

Well i have following information by german dji support:

The M3Cine Rolls its Gimbal (at Row 1 and 3 to the inside) for a higher degree as you tilt it down when starting a 3by3 Panorama. And i can confirm that - when i begin a 3by3 with 0 degree tilt i have no issues. When i begin it with -15 degree tilt you will see images at row 1 and 3 like below. Therefor the Roll is different at every of the 6 images in the Row 1 and 3. This is not processable by lightroom. You can indeed process it with ptgui or autopano giga or different specialised software for stitching. Thats a real bummer for me too - but dji says its a feature to make in-drone stitching faster...

    Whether or not you can use perspective depends on the angle of view, so the fact that you can do this with a different drone model does not say anything. Think about it: how on earth would you create a perspective panorama that covers a greater than 180 degrees view? I'm not saying that the Mavic 3 Classic does create a larger than 180 degrees view (I have no idea what it creates), but I trust you get the idea. Perspective stops at about 120 degrees in practise.

    I'm looking for a solution on this very specific issue using a specific drone and softwore not an opinion. 9 images is not 180 degree. 21 images is 180 degree.

    Why such hostility? I'm trying to help by giving a possible explanation, based on facts, not on a personal opinion. If Lightroom cannot stitch using perspective projection, but it can stitch using the other two projections, then the most likely explanation is that the resulting angle of view is getting too wide. I only mentioned 180 degrees as an easy to understand example why perspective projection fails beyond a certain angle of view, but I already said that the stitching failure occurs much earlier in practise. Granted, maybe that is not the correct explanation in this case. I do not claim to know everything in the universe. I already mentioned that I do not even know how wide a 9 images panorama from this drone gets. That's up to you to check and then you can draw your conclusion if this could indeed be an explanation or not.

    Try Cylindrical or Spherical. Cylindrical if just one row, Spherical if multiple rows/columns? Or just try one then the other and see what you get.

    Cylindrical and Spherical works but the outcome is very different from perspective. I have tried exporting images and use PS but still cannot make proper perspective stitches. As I said the panorama files from Mavic 2 works perfectly, some the images from Mavic 3 classic all don't work.

    I find that on my non drone cameras, perspective sometimes fails. Heck sometimes Spherical

    fails but perspective works.
