Stitching together multiple flights with waypoints
Hi,
I want to create a set of missions that overlap so that I can edit it into one continuous flight.
But I find it hard to create missions/waypoint that results in a "perfect" overlap. Have anybody tried this? Do you have a tip for how to (in a simple way) achieve a "perfect" overlap?
The best way would probably be if one could design the complete mission and then split it afterwards, but that would be a feature request.

Not sure I entirely understand what you are trying to do.
Sorry about being unclear. The situation is this:
My (and any drone) is limited by range and battery capacity so it cannot do long plans, like this:
https://app.dronelink.com/rune-winsevik/test/plan/9jY7BYqszpdK1BASaxXP/jx2YDUTqESwzgFY3A81L
Therefore, the only way is to split this into smaller "legs", then stitch together the video recordings of these parts to create one, long video.
Now, the challenge with this is to have "perfect overlaps" where one part ends and the next begins so that the transition between the videos are as invisible as possible.
It is this challenge that is my original question. How to go about splitting such a long plan into smaller sub-plans and maintain an "overlap" (sorry, I don't know a better word for it) at the start/end of each sub-plan so that there is, say 15 seconds, where I can do the video stitch.
The drone has to have the exact same speed, bearing and position during these "overlaps".
I guess the ultimate solution to this would have been for Dronelink to directly support this, for instance by having a "Add break" feature, where the user can set a break position in the path and a landing/starting site or something. I don't know, I haven't thought that much about a built in feature :-)
The way to do this would be to disable any take off restriction you might have, and then enable dynamic home point so you can follow along with the drone in your car:
When the drone reaches the end of a battery, it will automatically attempt to RTH to your current position (due to dynamic home point) and you can swap the battery and let the standard mission resume behavior handle getting the drone back to the same exact position and speed.
You should also enable terrain follow by adding markers along the path with AGL altitudes specified. If you use a mobile device that has GPS, it will automatically adjust the altitudes during each resume by accounting for the GPS altitude reported by the device.
Doing such an operation is not easy, and may not even be legal in your jurisdiction, but this is the process.
Ok, thanks for the explanation.
But I'm afraid this way of doing it is clearly illegal in my country. I was actually planning to do take off, run the sub-plan and land at the same spot. All with LoS (more or less). It will be cumbersome, but legal.
If that is the case, then you can still do what I said, but you don't need to enable dynamic home point. The drone will just have to fly all the way back to your current takeoff location and then you can move to a new location closer to where it disengaged previously.
Thanks, most is clear ny now. I guess the same thing happens if the drone reaches end of battery and if I init RTH myself?
I guess it is the "standard mission resume" that I do not know enough about then. For this to work, the drone controller must be on during the entire session? Is the details of "standard mission resume" described somewhere or have you made one of those great videos about this?
This is the standard resume behavior. Just plan a test mission and try it for yourself.
