I agree - it seems Litchi is the way to go.
Hello,
I have a project with FAA, and one of their requirement is to get the azimuth reading of the phantom's heading in-relation to North. Also is it possible to have this display this reading on each pictures I take?
Thank you
Thank you T (Sagebrush), I'll look into it. BVC, I don't know the details of the project, but they want me to take pictures at certain coordinates, altitude and a 360 pictures with heading information.
It would be helpful if you knew exactly what they wanted. Do they want four pics going around? Eight? Sixteen? It would be a lot simpler if the info you needed would be displayed on the FPV screen as you shoot, but I don't think a P3 does that. Litch doesn't. Maybe some other drone does? I don't know. Let's say you're forced to use a P3.
Here's an idea. Maybe not a good one.
Make precise waypoints missions in advance using the flylitchi site and download them to your device. The flylitchi site shows the GPS coordinates for your waypoints, so you can fairly easily find the exact spot you need that way.
To get your first photo, you could set three way points at the required altitude in line with one of the required GPS coordinates. Let's say the first photo will be a 360 degree photo showing due North. So the first line would be S-N. As your waypoints increased from 1 to 2 to 3 the first GPS number in the coordinates shown would decrease as it moves north but the second number in the coordinates would stay roughly the same). The middle waypoint would be the exact coordinate that the photo requires. As the aircraft approaches and pauses at the 2nd (exact) coordinate, you plan to snap your photo(s). The aircraft will continue to move a bit, and the directional heading might change a bit as the software pulls the aircraft back, but you know the nose heading is exactly what it was just prior to arriving at the 2nd way point. The nose heading will be perfect.
Repeat for all the other required photos. N-S will give you the 180 photo. E-W will give you the 270 photo. W-E will give you the 90 photo. Etc.
Now go to the field and let it fly. Take your photos.
When you're finally done, look at your Litchi log to get all the info you need and manually overlay it onto each photo. The Litchi log would include GPS coordinates, altitude, and the directional heading info which you will use as the required nose heading.
The process will be a PITA no doubt.
