A fascinating example of applying computer vision. Thanks for sharing details and posting the code.

Your skill and interest in this field is amazing. I only have an esp32 and was waiting for buying a raspberry pi but the shortage ruined it. So I cant replicate it ;( Cheers on the good work

[BooDevil]

Awesome, I must try this! I do vision systems for defect detection professionally, and at home have an unused rpi4, a brand new pusher plane kit that I got 2 days ago, and an extra GPS receiver 😁

Keep up the good work!

you can use ELRS with an sbus(i think it's the protocol on the RX output side) library if you want more range and consistancy, and want to reduce weight. A bit of a tangent to your goal, just in case you need it!

You could also get a pwm ELRS receiver, but that's more than 1 wire, but you're using the RX as PDB so might be a better option

Future Ghost is back, after ingesting the rest of the awesome: You're doing this with a Pi Cam 2?!!! I assumed you had the mythical HQ Module with a long-ish lens (the cam 2 is 62 degrees FOV, but the discriminator shows about 10 degrees of sky and horizon, no?). Sorry, this is absolutely fascinating. Last question, I promise.

[StuartRobinson]

awesome video thank you -- looking forward to part 2!

[elektronkim]

Thanks. I want to do this on some level with a Pico/MMBasic and already have a PWM Throttle function similar to a tester. Some sensors should be able to provide "something" to start with and flying in a straight line for some time would be a pass.

This is very promising! First time I see computer vision on an RC plane. I wonder how more complex the software can get if you feed the footage to a laptop and perform the computer vision there.

[bernardolorenzini]

Can you show us how you linked the buck converter to the raspberry?

[nakilakeddys.]

Hello, im from the philippines, i hve a question on the flight computer. Is it good to use raspbery pi or arduino?

[SzybkiPolonezGSI]

Great stuff man, Im currently working or should say sstart buying hardware for it and I am not too familiar with the electronic, however even if I crash this I'd have some joy on working with that.

So in theory I can have one LiPo Battery for the whole setup meaning, servos, ESC and motor, pi controller, however this needs voltage converter for pi and servos right ? I My limit for motor is 5s and they are pretty rare, however if I use one 6s battery for everything voltage would drop down eventually and should work ok, another options is larger propellers. My ESC is 50A and engine is 1100 KV and 911W.

initialy I was thinking to only use one battery for ESC and motor and another setup for the rest, but now I think that minding the weight it may be not ideal.

Please just be aware that I am completely amatour and still leaarning this by having a goal to do something working 🤣

[IgorWolkov]

@timmarkhuff could you please explain how do you stream the video from the camera connected to RPi? Thank you.

[Willy_Tepes]

So you are using one voltage converter for the Pi and one for the receiver? How many amps does the Pi actually need? You can easily get 3 amps out of a esc with bec. Size and weight does not seem to be an issue here, but this setup could easily lose over half it's weight with some planning.

[smol]

How would I go about finding a plane that does not come with a receiver or anything?

[mukeshbaskaran]

Are you not controlling the thrust (i.e speed of your motor) using raspberry pi?

[mrmoonrc]

👍I looked at the sources. seems like I might dare. but where do i choose the pins for the servos etc.? Didn't find this in the GitHub sources. thanks.

[ja_ja_wunderbar]

Hi, are you still active in the project? Will there be another part/update? Thank you! :)))

[peterboy]

Subscribed. I should revive my codingskills...

[jebeandiah]

how hard would it be to use crsf instead of sbus

[hamzaehsan]

This was amazing. I have some experience wit computer vision and drones but needed a little guidance when it comes to hardware. I am trying to work on rasberry pi powered autonomous check point script for my aeroscout.
