I was dissapointed to see the same kind of problem today.
I'm new to the world of drones and today was my first time out with my M3P. But I do have years of experience shooting 360 spheres on terra firma with a regular camera and pano-head.
The first pano I did, I shot manually with AEB. I already worked out at home the FOV and how many rows and turn increments I needed to get full coverage with sufficient overlap.
I did 3 rows of 8 (45deg increments) plus a nadir. Top row at +60 pitch portrait. Second row at +10 landscape. Third one at -40 portrait. Then the -90 nadir. Stitched in PTGui, it worked a treat.
But finding the process of manual shooting at bit tedious and time consuming, I went on to try the automated 360 shooting. This of course was much faster and easier. But when I got home and looked at the results on the computer, they were dissapointing. Every one of the auto panos had this kind of stitiching alignment issue. I can't say it was particularly windy, there was a little wind, but not strong. The resolution isn't great either.
>Only possible if you shot in both raw and jpeg. The jpegs are used to create the final image but are discarded by the drone afterwards. The raw files remain on the sd card.
That's good to know for future, as I only shot jpeg this time. TBH I did not get too deep into camera settings today. Being first time out, I was concentrating more on getting to know how to handle it in the air and I'm not yet fully familiar with the DJI Fly UI. So I thought it a lot to take in at once, so left the camera in auto mode. Though on the ground with my camera I put everything on manual for pano shooting, for consistancy in frames.
I'll have to experiment more on my next outing. Maybe try auto panos with raw. But also some manual shooting. Maybe compare using raw against AEB.
Though I only foresee manual pano shooting and stitching yielding the best results. It's just a bit laborious to do. I found getting the 45deg turns precise tricky. The compass view helps to some extent, but it would be nice to see a numerical heading for precision, like you see for the gimbal pitch.
One thing I was pleased with was when I loaded the manual images into PTGui, it knew the (approx) position of every frame, so I had a rough alignment from the start, which is a huge help. Especially as today was a dull, grey, featureless sky. There would be no contral points, so I would have to manually place all the top row. But being in the right place from the start, the bland grey sky blended seamlessly.
This was the first pano, shot and stitched manually.
This is an auto pano, with a brokn horizon.
OK, I managed to fix it with some monkeying around in Photoshop. But I would rather not have to. |
