👍can't wait for the next part. 😊
A fascinating example of applying computer vision. Thanks for sharing details and posting the code.
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.
Tim, good job!
This is so cool!
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!
lol I'm in the same boat as you!
i love this channel
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
Excellent!
i cant believe its so simple!
nice project) ty
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
Same principle. You can do this with an Arduino.
awesome video thank you -- looking forward to part 2!
It's coming soon! Stay tuned
@@timmarkhuff😢
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.
Love it would like to see the pi zero 2w or the zero
nice projected
Extremely cool! Is there any reason not to use normal IMU? Looks bit more challenging and prone to fail in case of poor visibility.
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.
Or what about putting a more powerful computer on the plane, like a Jetson. I might go in that direction at some point
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.
I have an HQ camera and I originally intended to use it for this project, but I learned two things: 1) it’s very heavy with its lens, not good for flying on small planes 2) the normal RPI camera captures plenty of detail for what I am trying to do. No need for HQ. Of course, it might be nice to have an HQ camera just to get better video of what I am doing, but it won’t make the program run any better.
The FOV of the Camera v2 is 48.8 according to the documentation. The horizon detector uses this value to calculate the pitch.
@@timmarkhuff Holy crap, I saw the new Global Shutter Camera from Pi, and thought of your project. Not sure if your system suffers from rolling shutter, or Jello, or any CMOS specific issues, but take a look: ua-cam.com/video/1r9AxhCZclc/v-deo.html
@@timmarkhuff The HQ camera is heavy considering what most people would use it for on a plane. As a downward looking camera on a larger motorized glider, it would make sense for things like object detection and tracking. Lost sheep and such. ;)
Dogfight Blick😮😮😮
Hey is part 2 coming?
Hello, im from the philippines, i hve a question on the flight computer. Is it good to use raspbery pi or arduino?
@timmarkhuff could you please explain how do you stream the video from the camera connected to RPi? Thank you.
It’s a raspberry pi camera v2 connected directly to the raspberry pi. I used cv2.VideoCapture to interface with the camera
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.
Thanks! I'll look into that
👍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.
Thank you for your interest in the project! The GPIO pin numbers are passed into the TransmitterSwitch and ServoHandler objects in main.py. Please note that the version on GitHub is a slightly older version than what I use in this video. The version you see on GitHub does not use SBUS, but rather reads each output from the receiver using different GPIO pins. I plan to have the updated SBUS version of the code up on GitHub soon, but it still needs more work at this point.
@@timmarkhuff thanks! So I should wait...
@@mrmoonrc I would wait. The next version will be better and easier to install and deploy.
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 🤣
If weight is a consideration, getting a buck converter to convert the voltage for your raspberry pi is the way to go
@@timmarkhuff Thanks :)
Are you not controlling the thrust (i.e speed of your motor) using raspberry pi?
I am not. Haven’t figured out how to measure airspeed yet, so I wouldn’t be able to control throttle
How would I go about finding a plane that does not come with a receiver or anything?
Search for “plug and play” airplanes
Hi, are you still active in the project? Will there be another part/update? Thank you! :)))
This project has been on the back-burner for a bit, but I’m getting back into it now. I hope to have a new version available soon that controls the rudder and reads SBUS packets from the receiver. Stay tuned!
how hard would it be to use crsf instead of sbus
I’m not as familiar with that protocol, but in theory it should be possible. I found a Python library that can read SBUS. Perhaps there is something like that out there for CRSF, or if not, perhaps it could be created.
at last you can use CRSF to SBUS converter from Matek or any other
@@timmarkhuff its rather simple. buzz trappy for spec pdf, takes 100 lines of code max.
is ELRS sbus or CRSF on the RX output ?
never mind its CRSF
Subscribed. I should revive my codingskills...
Absolutely!
Still waiting for software part.😢
It’s coming soon! Within a couple weeks I plan to have a version that’s ready to release
You have code sbus?
I was working on a proof of concept here: github.com/timmarkhuff/horizon_detector/tree/sbus, but it's not really complete. The code I wrote uses an SBUS library provided here: github.com/VermontCoder/read_sbus. I have also had some luck using this C++ SBUS library: github.com/Carbon225/raspberry-sbus. Let me know if any of that is interesting, and I might be able to make a video on it.
