First flights, first problems?

just got my Mavic Air last Weekend. I didn’t get a chance to really fly it due to a relative visiting from out of town.

I did hover it in my living room. I noticed it kept climbing, but was fine as soon as I pressed down on the left control stick. I figure I must have checked “precision landing” and it was attempting to climb to the right altitude. No big deal.

I took a 360 pano in my living room. There were some stitching artifacts, but I figured, well, it is in my living room, what do I expect?

Today I took the the drone out into a State Recreation area for it’s first real flight test.

While the drone did not ask me to calibrate, I went ahead and did it anyway per the flight manual instructions. It took me a few times to calibrate correctly, but eventually after moving it far enough away from a large volcanic rock it calibrated fine. I launched the drone, it launched about 4 feet. Hovered just fine, and eventually I took it up to about 300 feet to do a 360 panoramic shot. The shot looks fine, no real problems, also had no problems controlling or landing the drone.

After hiking about 2.5 miles I launched the drone from another location, this time from a metal boat dock. Up on launching I noticed that the drone continued to gain altitude, precision landing was not checked. I watched it until it was about 25-30 feet up before I decided it might keep going up and used the left control stick to bring it back down.

One back about 8-10 feet above me, the drone started drifting to the left. I was starting to wonder if I had a poor GPS connection, but everything on the controller seemed fine. When I brought the drone back to me, the drone did not fight me, and taking my hands off the sticks, it seemed to hover just fine. After waiting a few more seconds, I did a full 360 yaw, and after assuring that the drone was maintaining its position I went ahead and moved it in position for a 360 photo.

This time the 360 photo turned out horribly. It had very obvious stitching artifacts in it. I’m not sure I’d the stitchimg artifacts are just Normal for 360 photos or if it may have been due to the drone having difficulty with maintaining its position. I have attached a copy below

Some questions:

Would “Tripod mode” help with 360 stitching?

Are stitching artifacts just normal with curennt technology?

Note: I hand launched from the end of a metal pier, and was flying over water when the drone seemed to be showing difficulty maintaining position.

I'm surprised it let you take of from a metal launching area. I would think it would as you to calibrate the compass. Unless the docks were aluminum then maybe not. Metal can mess with the compass and cause the drone to do kinky things, like drift and make it hard to control. Try different launch sites away from metal, make sure the home point is set before take off and see if you still have the same problems.

It was probably aluminum. Wouldn’t be surprised if launch site was the issue.
 
I might be wrong, but did you have automatic exposure settings for your pano'?? You'll get better results if you set manual exposures so that you don't get the light level changes in the frames that you stitch ...

Yes, auto exposure. Thanks for the tip.
 
I tried my first couple panoramic images the other day, noticed where it was stitched together as well. In future I am going to let the drone save the unstitched images (in RAW format) and just stitch then myself using Lightroom or Photoshop.

I’m considering something similar. Still wondering if tripod mode might help?
 
I don't think tripod mode will help to be honest, my understanding is it slows the drone down, but taking pano images, the drones not really moving anyway, just rotating, moving the gimbal. It may help a small amount, but I'd imagine if there's even the slightest bit of a breeze, any additional movement to the drone, it's not going to help much at all.

I am going to use Lightroom, since I can then edit the images before stitching them together. Might try a couple out later today, flying conditions look good all day.

I’ve heard Microsoft ICE ( image composite editor) works well. Never tried it myself.

ICE Works very well, even with huge RAW files. And it’s free!

OP has to lock down exposure somewhere between the brightest and darkest part of the image. If there’s a sunset in it, underexpose it just a bit. But as you go around taking the other shots, do not reset the exposure at all. It will produce a very nice pano.

After you get really good at this, try doing HDR panos - but that’s another lesson.
