while I saw this thread:
I am wondering if there are some updates on this.
I created a new thread as the old on is already long (so is my script below ;-) I'd appreciate if someone could help with this. Maybe this could turn into a beginners cookbook for this type of usage of the Disco?
Brief background info:
I bought a Mavic Air a while ago and when offering photographies over here (Germany) to my clients got approached to fly a mapping mission over 500acres of forest.
So I started looking into fixed wing drones. The possible solution needs to be low budget, as there is only this client for now (even though I am surrounded by farmland, I might find more..) and I have not enough funds to go expensive right now.
Second hand Parrot Disco consumer models are very cheap now, so this will be the airframe of choice.
I am not at all a programmer but, as the consumer version of the Disco has no proper mission planner I am now looking into Ardupilot.
As I am new to this Ardupilot & the programming thing, I need some not too technically worded guidance. I run on Android & Windows 10.
A) Mission planner, which one?
I noticed there are several mission planner apps around. Which one is the best suited to someone not firm in programming and really needing a proper GUI? I'll fly primarely fixed wing grid type missions and want to fly fully automatic. I really lack the know how at this stage to understand the details.
So far I found:
Some comments of what I found so far:
Most intuitive user interface, but I cannot find a way to set it to fixed wing.
Custom camera spec can be easily added.
90Deg offset of pattern greyed out.
Has a lot of options to customize a flight plan.
Lots of different flight plan patterns
Good user interface.
Custom camera spec can be easily added.
-Ardupilot 2 (APM)
I could not find a way to create custom survey patterns automatically.
Feels unfinished. Possibly still in development.
Any other & better suited ones?
B) Camera, which one?
I have looked into cameras, my clients will most likely need:
Orthomosaic RGB, NDVI and, in case of forest, a 3D model.
One question upfront, can one receive the front camera when flying with Ardupilot and an after market remote control?
Unfortunately the best lower budget multispectrumsensors are still quite expensive (Parrot Sequoia & Micasense Red Edge) so thats not a low budget solution.
Mapir does some interesting cameras too, but their Survey 3 model does not seem to save IMU roll angle in the images. On a fixed wing without gimbal that seems an issue.
Is it somehow possible to add that roll data to the images via data from the CHUCK? Automatically?
If yes I am thinking about putting these two onboard (possible swapping them and do two separate flights).
Did someone install a downward facing cam with an added gimbal to the Disco airframe?
Alternatively which GoPro (or something completly different?) is best suited? Do they have IMU roll data?
Does the increased internal stabilisation of the Hero7 make it much more desirable to use than the Hero 5 or 6?
Does one need to replace the lens on the GoPro to take out the fisheye?
Does it matter if the NDVI is taken with a different lens than the RGB (like flying RGB with a GoPro & NDVI with a Mapir)?
Obviously its a compromise of extra weight vs power? S
till for the 500acres I need a long flight time (or two flights).
I am leaning towards this one as a compromise, as the drone has to carry the extra cam & receiver & tracker as well.
Any better suggestions?
As I understand I need an after market remote to fly with Ardupilot.
Something like the FrSky Taranis X9D.
What receiver model do I need exactly?
There is no other simple way to upload a mission plan to the aircraft otherwise?
Using the Skycontroller (which comes with the drone) to start the craft and than have it fly fully auto is not possible?
E) Post processing?
I'll lean towards Pix4D or WebODM.
The missing IMU roll angle of the Mapir camera seems an issue. How about the Gopro's?
Any thoughts on this?
Thanks so much for any input, suggestions & help you can give to a Newbie.
Sorry about the long post,
