Yeah it's pretty impressive, obviously a much beefier computer will get faster frame rates and be able to track more objects simultaneously, but for getting started in computer vision systems its a great starting point.
Using Coral TPU definitely provides a significant boost to performance for all computer vision tasks when utilising a Raspberry Pi. Definitely something work doing 😊
Will a Rasberry 3 work? It seems that the Rasberry 4 is in very short stock, so I was wondering if a raspberry 3 has enough power, I won't be using the high-quality camera but the V2 camera module. I also want to connect this to Arduino Uno, will this be possible?
I reckon hand and finger recognition may be asking too much of a Raspberry Pi 3, but I'd love to be proven wrong. And there is lots of ways to hook up a Raspberry Pi to send information/instructions to a Arduino so that won't be an issue, they also both conveniently run at 5Volts.
Thank you for the wonderful project and tutorial, i just want to ask if how can access those specific joints in the hand so that I can compare my custom made specific hand gesture?
So I have a plan to create a software that records the motion of your hand and essentially moves a prosthetic arm the same way. Do you think that software would possibly be able to accomplish that goal? And, I'm just wondering if you think that this concept would be able to match a hand's movement well enough. It's fine if you don't know :), I'm just curious. It's for a school project far off in the future but I'm planning in advance because engineering is my passion so I want to succeed while having fun
This set up is definitely pushing the Raspberry Pi very hard. However if you save the Raspberry Pi from printing each frame to the screen and overlaying each frame with the wire frame over the hand by customising the Main scripts there will be enough computing power inside a RPI4 to do your task without lag 😊. Mind you I even did that! Just remembered - Come check the Where to Now Section in the main guide and you can see me controlling a hand - core-electronics.com.au/guides/raspberry-pi/hand-identification-raspberry-pi/ And a good mate Garry edited the provided code here to control a Lego hand he created - th-cam.com/video/cadqkqh0zAY/w-d-xo.html

Heya! I've been trying to get this setup working with my Raspberry Pi 3B, running Buster (as mentioned in your article), along with an Arducam IMX519 (It's a 3rd party alternative to native Pi Cameras). The only issue is that my Arducam requires a Pi running Bullseye to work. Since it's been over a year since you put this video out, I was wondering if I could replicate your setup but switch buster for bullseye?
Definitely would be sweet to update al the AI guides l for the newer version of Bullseye. It has a very different software architecture to Buster so I'm hesitant to take the plunge.

Heyya mate, thank you very kindly. My first two thoughts are whether you used the older 'Buster' Raspberry Pi OS or did you skip one of the MediaPipe installation Terminal commands. Type the following lines one by one into a new terminal command to try to get that MediaPipe to work. sudo pip3 install mediapipe-rpi3 sudo pip3 install mediapipe-rpi4 sudo pip3 install gtts sudo apt install mpg321 We have a heap of successful troubleshooting that you can find at the comment section of the full written up article - core-electronics.com.au/guides/hand-identification-raspberry-pi/
No doubt the teams at Open-CV and Raspberry Pi are working furiously to reach full compatibility with the new OS versions. That hasn't happened yet, so until then I would recommend using the previous Raspberry Pi 'Buster' OS with this guide.
Hey mate, this system is completely running on the Raspberry Pi 4 Model B. You can definitely run this system Headless (without a Monitor/Display) and still control hardware through hand signals.

In it you will see a section that has been commented out which is the code I used to find the location of the index finger in the video. Copy that section across to your desired script and replace Index Finger ID number 8 with the Thumb ID number 4. Hope that helps!

INFO: Created TensorFlow Lite XNNPACK delegate for CPU.
Hey mate, just to start with the simple stuff first, double check you have the camera enable in the Raspberry Pi Configuration and that the camera is connected correctly to the CSI port. If you keep running into issue, pop me a message in the comment section of the article as I will be able to help you easier there 🙂
Gstreamer warning will go away if you use line:
cap = cv2.VideoCapture(0, cv2.CAP_V4L2)
When i set up Open CV, there is a error. Should I contine the progress with error?
Hey, if you are still having issues we have a forum topic specifically on this video that might have some helpful information. If you are having a unique issue, feel free to post in there, we have lots of maker eyes over there that can help!

@@Core-Electronics Thank you so much! Your video is very helpful to raspberry pi user!
How can I learn Python like yours?
W3school is a good begginer option
hey, I'm having a problem where because the code is old, it doesn't work with the 3.7 version of python on thonny. could you possibly make an updated version of the code or give me a way to downgrade the version of python I have?
Hey, we're currently updating our Raspberry Pi Computer Vision guides to be compatible with Raspberry Pi 5 and make them a little more future-proof against hardware and OS updates. We should have one on hand tracking and gesture control soon!
hello, Can you advise me please? I have done all the steps according to the tutorial but when I run the program I get an error: TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
If you aren't already, ensure that you are using Buster OS, this guide only works on that version, we also have a dedicated forum page for this topic with lots of maker eyes over there that can help, feel free to post on there with your code and setup!

I need help in website " If it fails at any point and you receive a message like | make: *** [Makefile:163: all] Error 2 | just re-type and enter the above line | make -j $(nproc) |". Same like for me also error come i repeatedly that cmd but same error again and again 😢
Plz reply ASAP

Genial ❤️
Gracias 😊
A Bit of trivia for you from an American Sign Language Interpreter… The gesture You and many others use as ‘Rock & Roll’ Really means ‘Bullshit!’ In American Sign Language. I laugh every time I see it being used.
Haha, thanks for sharing
Made the mistake of updating my WIP robot with Bullseye, so now I can move it around but not using its camera in python, doh
I made a quick guide on how to deal with the new camera terminal commands for 'Bullseye' OS. It might come in handy for you - core-electronics.com.au/tutorials/raspberry-pi-bullseye-camera-commands.html
@@Core-Electronics yeah saw that, had a play, still waiting on python libraries, might format a new card and go back to buster need to play with open CV too as I have the pi cam on the robot frame pointing forward and a USB cam on a servo pan tilt for looking around. Still such a coding n00b.
I love the sound of that project! Excited to see what you come up with 😊 come make a post on our forum to show it off/if you need any help forum.core-electronics.com.au/
Is it possible to run this on a RPi zero 2W??
Hi, is this possible with raspberry pi 3 b+?
This set up will work with a Pi 3B+, but it may be a very slow and laggy experience :(
