I will show you exactly how to have your Raspberry Pi credit card sized computer be able to spot human faces, how to train it to know your face and run code so that it will successfully identify you when it sees you. Then I'll take it another step and show you how you can use your face to control a servo attached to the Raspberry Pi. Open Source Software and Raspberry Pi go together hand in hand. Two excellent examples of this are OpenCV which provides a huge free resource to solve real-time computer vision problems and the Python Face Recognition Package which computes bounding boxes around a face in real-time. With it working we can do so many things with this now. Simply to start can now jump into the folders with the Python code and alter some lines of code so that every time a known face is seen it will send out signals via the GPIO pin of the Raspberry Pi. These GPIO pins can be used to control an almost endless amount of sensors and mechanisms. In this video I will get a servo to rotate when the Raspberry Pi system sees my face. If it sees someone else face or nobody's face it will not activate the servo. Huge thanks go to the Open-CV and Facial Recognition Package teams that work on the amazing machine learning software that we have running on the Raspberry Pi. Both are really good Open Source software. Also a huge thank you to Caroline Dunn whose created the amazing software that makes these two systems work so well together. There is just so much potential with this software to take projects to amazing places.

Cool stuff, this was my disertation project!

Also a good thing to look at is a PID controller. Cheers!

Hello! Great tutorial! Is there a way where we can improve the frame rate? The program is able to recognize my face but the frame rate is very low. I am not using a raspberry pi camera, just a random USB webcam. Also, I am facing an issue where another person comes into frame, instead of showing "unknown", it displayed my name instead. I tried taking 40 images instead of 10 but the result is still the same. Please let me know if you have any way to solve this. Thank you!

@Core-Electronics 2 роки тому

Can I ask which Raspberry Pi you are using? Using the highest Spec Pi possible is always my first recommendation. Using a TPU accelerator like the Google Coral edge TPU will also provide some signification FPS gains. Also it surprises me that it isn't identifying correctly, potentially providing it with fewer than 10 images will yield better results in your particular use case. Hope this helps!

@Core-Electronics Рік тому

You can run face detection without a display. So if you can remotely/headlessly start the Python Script (using your phone like this guide here is a good way to do that - core-electronics.com.au/guides/raspcontrol-raspberry-pi/) it'll run just like normal. So if you ran that servo script, if you showed it your face it'll work as it should and activate that servo, with or without a display. Hope that helps 😊

The other option is to create a Custom Image of your Raspberry Pi instance. This Image you can then use to flash other SD cards, speeding up the process as you will just need to flash the SD card with your already Face Installed image.

Not working I installed all libraries but i still getting errors. Some errors I fixed but i can´t fix: "AttributeError: 'NoneType' object has no attribute 'shape' " maybe you can make full tutorial with installing all libraries etc.

The full article does go through the whole process of installing Open-CV but it would definitely be worthwhile making a video guide on the process, particularly once Open-CV and the new 'Bullseye' Raspberry Pi OS release has full compatibility. In regards to fixing your issue, it is important to run the old 'Buster' Raspberry Pi OS as this currently is the only compatable OS with Open-CV. Here is a guide on how to do that - core-electronics.com.au/tutorials/flash-buster-os-pi.html. If you still run into issues open up a forum topic and I'll help you through the whole process there 😊

What if I want the data of detected persons to be stored in the memory, and the second part is that Can I detect objects and save them with the data of a specific person who detected the object in the camera?

@Core-Electronics 2 роки тому

You can definitely alter the code so that it takes a snapshot/video recording every time a face is seen. In regards to object detection I've put together a guide on doing just that, linked in the description. Combining both Object and Face detection as a single system is doable, something I'd love to pursue.

Sounds like some weird camera issues. Come jump on our forums and write up a post 🙂 we will be able to help you best there. forum.core-electronics.com.au/

if i use a usb webcam does the camera still work? sorry newbie.

@Core-Electronics 2 роки тому

Absolutely it will work - some things will need to be altered in the Scripts and a different script needs to be used to take the initial images that it learns from but everything you need is provided in the written up guide 🙂

How do I reduce the quality of my camera? It defaults to 4056x3040 which is way too large and it drops my frames like crazy. I have the RPI 4 8GB RAM

@Core-Electronics Рік тому

In the main script you will find this line of code | frame = imutils.resize(frame, width=500) |. Edit that 500 to be a smaller number to increase your FPS 😊

Hi, when I try to execute python facial_req.py I get the following error [ WARN:0@5.322] global /home/pi/opencv/modules/videoio/src/cap_v4l.cpp (902) open VIDEOIO(V4L2:/dev/video2): can't open camera by index. Is this an issue with the OpenCV installation?

@Core-Electronics Рік тому

Come jump onto the Full written up article and check the comment section. A lot of successful trouble shooting can be found there. This is a Camera Index setting that you just need to make a quick adjustment in the Python code. I talk about it explicitly in the bottom paragraph of the Demonstration section - core-electronics.com.au/guides/face-identify-raspberry-pi/#Demon

Hi there, we downloaded open cv in diff path, we are trying to run your code but face this prob -> _model.py Traceback (most recent call last): File "/home/pi/raspberry-pi-opencv/facial_recognition/train_model.py", line 5, in import face_recognition ModuleNotFoundError: No module named 'face_recognition' Anyone help!

@Core-Electronics 2 роки тому

Would definitely recommend going through the process outlined in the Written article. I ran into all kinds of problems trying to download Open-CV and getting it to run using different methods/paths.

Hi guy. Fps in my project is less than 1. Can you instruct me to increase fps to recog faster? Thank you very much

All depends on the hardware that you are using. If you want some real fast Facial Recognition that can get fed into a Raspberry Pi check out this product here - core-electronics.com.au/luxonis-oak-d-depthai-hardware.html
