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

@hamzaehsan404 11 месяцев назад

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.

@shivavarunadicherla Год назад

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

@Willy_Tepes Год назад

Same principle. You can do this with an Arduino.

@tenns Год назад

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

@GhostRyderFPV Год назад

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.

@timmarkhuff Год назад

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.

@GhostRyderFPV Год назад

@@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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1r9AxhCZclc.html

@Willy_Tepes Год назад

@@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. ;)

@elektron2kim666 9 месяцев назад

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.

@BooDevil65 Год назад

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!

@charimuvilla8693 Год назад

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.

@timmarkhuff Год назад

Or what about putting a more powerful computer on the plane, like a Jetson. I might go in that direction at some point

@ChantOfSpirit 5 месяцев назад

Tim, good job!

@janoshorvath9430 10 месяцев назад

Extremely cool! Is there any reason not to use normal IMU? Looks bit more challenging and prone to fail in case of poor visibility.

@IgorWolkov 4 месяца назад

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

@timmarkhuff 4 месяца назад

It’s a raspberry pi camera v2 connected directly to the raspberry pi. I used cv2.VideoCapture to interface with the camera

@SzybkiPolonezGSI Месяц назад

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 🤣

@timmarkhuff Месяц назад

If weight is a consideration, getting a buck converter to convert the voltage for your raspberry pi is the way to go

@SzybkiPolonezGSI Месяц назад

@andreyl2705 11 месяцев назад

nice project) ty

@MrTully Год назад

This is so cool!

@bernardhfox Год назад

Excellent!

@Willy_Tepes Год назад

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.

@timmarkhuff Год назад

Thanks! I'll look into that

@smol2844 6 месяцев назад

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

@timmarkhuff 6 месяцев назад

Search for “plug and play” airplanes

@mukeshbaskaran2557 2 месяца назад

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

@timmarkhuff 2 месяца назад

I am not. Haven’t figured out how to measure airspeed yet, so I wouldn’t be able to control throttle

@mrmoonrc Год назад

👍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.

@timmarkhuff Год назад

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.

@mrmoonrc Год назад

@@timmarkhuff thanks! So I should wait...

@timmarkhuff Год назад

@@mrmoonrc I would wait. The next version will be better and easier to install and deploy.

@juan4972 2 месяца назад

You have code sbus?

@timmarkhuff 2 месяца назад

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.

@ja_ja_wunderbar Год назад

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

@timmarkhuff Год назад

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!

@jebeandiah Год назад

how hard would it be to use crsf instead of sbus

@timmarkhuff Год назад

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.
