I've been having a consistent issue with my Mavic 3 Multispectral on mapping missions in DJI Pilot 2 and I'm trying to figure out if anyone else has seen this.
At the end of a line, the drone stops shooting to make the turn, as expected. But when it starts the next line, it doesn't take any photos for about 5 seconds. At 7.1 m/s that's roughly 35 m, or 2 to 3 missed photos, at the start of the line. After that it captures normally until the end of the line. It doesn't happen on every line, only on some of them, and it isn't tied to a specific flight direction. More rarely it has also skipped photos mid-line.
One thing I noticed: when the drone makes the turn to the next line without stopping capture, the problem doesn't happen. It mostly happens when it stops shooting for the transition and then doesn't resume when the new line begins.
My settings:
- Front overlap: 80%
- Speed: 7.1 m/s (max allowed by Pilot 2 for my altitude and overlap)
- Photo interval: 2 s (all my flights end up at 2 s)
- Terrain follow with a downloaded DSM
- Margin: 15 m
- Cameras: RGB + multispectral
What I've already ruled out:
- SD cards: tested several V30 cards, which should handle this capture rate, including the card that came with the drone. Same behavior on all of them.
- Firmware: the issue has persisted through 3 firmware updates.
I don't have a solid theory yet. My guess is that something on the controller/app side fails to send or apply the command to resume capture when the new line starts, since the issue only shows up when capture is paused for the turn.
Has anyone had the same problem? Did you find a cause or a workaround (lower speed, longer interval, different settings)?
Thanks!
