Coco Dataset Library - cocodataset.org/#home
Have you ever wanted to get your Raspberry Pi 4 Model B to actively search and identify common household objects and commonplace animals? Then you have found the right place. I'll show you exactly how to do this so you can set up a similar system in your own Maker-verse. Furthermore, I will demonstrate how you can refine the identification so it searches only for particular desired targets. Then we’ll take this to the next step and demonstrate how you can alter the code to make the Raspberry Pi control physical hardware when it identifies that particular target. This guide is going to blend machine learning and open-source software together with the Raspberry Pi ecosystem. One of the open-source software used here is Open-CV which is a huge resource that helps solve real-time computer vision and image processing problems. This will be a second foray into Open-CV landscape with Raspberry Pi and Facial Recognition being the first. We will also utilise an already trained library of objects and animals from the Coco Library. The Coco (Common Object in Context) Library is large-scale object detection, segmentation, and captioning dataset. This trained library is how the Raspberry Pi will know what certain objects and animals generally look like. You can also find pre-trained libraries for all manner of objects, creatures, sounds, and animals so if this particular library here does not suit your needs you can find many others freely accessible online. The library used here will enable our Raspberry Pi will be able to identify 91 unique objects/animals and provide a constantly updating confidence rating. Machine learning has never been more accessible and this video will demonstrate this.

Excellent. I came to this after seeing the facial recognition video as it would help with a project I have in mind. However, after seeing this and how easy it is to set up and use my project will be more ambitious. Thanks again and keep up the good work.

[@mike0rr]

This was the fastest, cleanest comprehensive guide I have found on OpenCV for Pi. Only thing that would make this better would be an Install script, but even then I think its good for some manual work to be left anyways. Get peoples hands dirty and force them to explore and learn more. So cool to have the power of machine learning and Computer Vision in our hands to explore and experiment with. What a time to be alive!

Very glad you have your system all up and running 🙂 and I absolutely agree. Something about a machine learned system that runs on a palm-sized computer that you have put together yourself really feels like magic ✨✨

Your website, products and educational resources are amazing. I was wondering if you had any advice as to how to further train the machine to identify less common objects? I was hoping to use it for a drone video feed and train it to identify people, for basic search and rescue functions. I am a volunteer in my local community, hence my specific question :-)

[@Core-Electronics]

Such a good idea. Yet to find a project talk about it directly, but where I added the extra code in for the Servo control if you instead replace that with code to set up a speaker and activate it, you would be off to the races.

Hi Great Video! I know this may be unrelated but how about recognition of objects on screen without a camera? Is there any projects you know of that use AI detection to control the cursor of the computer when it detects an object on screen? Cheers

[@Core-Electronics]

Cheers mate and excellent ideas. You can definitely feed this system data that has been pre-recorded or streamed in from another location, would require some adjustments to the script.

Hi. I wanted to ask, do you think the raspberry pi Zero cam could be used as a substitute? I'm currently working on a project that involved Raspberry Pi's and camera's and have done a lot of research on what hardware to acquire, I haven't seen much benefit in using the V2 camera instead of the Zerocam. I actually think the raspberry pi zero cam has better specs for its price when compared to the V2.

Should work perfectly fine 😊. If the video data is coming into the Raspberry Pi through the ribbon cable I don't think you would even need to change anything in the script.

[@charlesblithfield6182]

Thanks for this. I want to use my pi to do custom recognition of trees from their bark in a portable field unit. I already tried an tensorflow lite and off the shelf database to do common object recognition. If I had a small need to recognize say 50 trees, how many labelled images do I need of each tree for the training data?

[@Core-Electronics]

Hi Charles, some Australian scientists concluded in a 2020 paper “How many images do I need?” (Saleh Shahinfar, et al) that the minimum number of data points for a class should be in the 150 - 500 range. So if you had 50 species of trees to identify from you'd need roughly between 7,500 - 25,000 images/data points.

For sure but you will need to create a custom Machine Learnt Edge system. Come check out Edge Impulse, personally I think they are the best in the game for this kind of stuff (and totally free for a maker) - www.edgeimpulse.com/

You're the most closet project of my idea in fact it's practically that. But I would like to run it 7/24 during a 10 day period ( my holiday) I would like it press a button 10 minutes after each time it identify a cat (mine) and nothing else : Here is a cat : wait 10 minute press the smart button ( I looking for a way to flush the toilet each time after my cats have done their needs ) is this possible/faisable with this?

[@Core-Electronics]

Definitely possible and an excellent project to eliminate a chore 😊 or make for an even more in-dependent kitty. The Coco Library used in this guide has | Cat | as one of the animals it can identify. And Raspberry Pi's are excellent at running 24/7. So I reckon your in for a project winner. If you follow through the Full Write up you'll be able to have a system that can Identify Cats (and only cats). That the hard bit done. Solenoids are a way to trigger the button, check this guide for the process on getting one to run with Raspberry Pi - core-electronics.com.au/guides/solenoid-control-with-raspberry-pi-relay/

[@bellooluwaseyi4193]

Nicely explain. Please do I apply this on new dataset different from this?

[@Core-Electronics]

It will require some dedicated effort but you can customise this object detection dataset using edge impulse. www.edgeimpulse.com/ That way you can add whatever object or creature you'd like 😊 I hope I understood correctly.

[@andyturner1502]

How do you transfer a data set to the pi do you store it in a file or does it need adding to the code.

Hey tim i am getting problem in installing opencv after unziping it

[@Osst197]

Can I also use a normal webcam?

[@wkinne1]

Will this work on an Orange Pi5? Raspberry Pi's are out of stock everywhere except from scalpers charging five times normal.

[@Core-Electronics]

I'm not sure honestly mate, if you can get it to run 'Buster' Raspberry Pi OS then I'll give it a solid positive maybe.

[@meghap5221]

I am getting cv2.imshow error while running object-ident.py in pi terminal, I connected pi via ssh. What should I do?

[@Core-Electronics]

Very clever doing it through SSH 😊. It shouldn't be an issue doing it that way so long as you go through all the set up process. If you come write me a message on the core electronics forum under this topic I'll best be able to help you. That way you can sent through screen grabs of your terminal command errors.

how to detect waste like lays packets ?

[@diannevila8837]

Hello can it be possible if you can join the animal, object and person or facial recognition at the same time? I'm working that kind of project could you help me sir? Please...

[@Core-Electronics]

Aww what an excellent idea! You will start wanting more powerful hardware very quickly going down this path. Come check out the Oak-D Lite (which is an excellent way to start stacking multiple AI system whilst still using a Raspberry Pi) - kzbin.info/www/bejne/bXPOeZaAqppqeck

[@diannevila8837]

@@Core-Electronics how about just identifying if it is an animal, things or a person or some kind of moving object and at the same time it will capture a preview picture of it? How can you make this? and also how to create like if the raspberry pi detects a person in can email to you but if it is not a person it will not email you. Hoping you can help me with my research

[@xyliusdominicibayan6215]

Hi, How can I run the object detection even without connection to laptop or manually running the code.

[@Core-Electronics]

You got heaps of different options. For example, you could run the script automatically every time the Raspberry Pi boots (using Cron Jobs, check here for a guide - kzbin.info/www/bejne/qHbVcoKgdqiHbNk) or you could run the code remotely using your phone (check here - core-electronics.com.au/tutorials/raspcontrol-raspberry-pi.html)

[@sefaocal8825]

hi, i am using raspberry pi 3 model B+ in this project. I uploaded the codes and was successful. But there is a delay of 8-10 seconds and it detects an object many times. You mentioned in the forum that we can reduce the latency by lowering the camera resolution. I can't find where to set this setting, can you help me? (I am using raspberry pi camera module v2 as camera.)

[@Core-Electronics]

Sure mate, lower the values you find in the line here | net.setInputSize(320,320) |. Make sure both numbers are matching. Most AI Vision systems depend on the inputted video data to be square. If you type | net.setInputSize(160,160) | it will yield faster responses.

[@sefaocal8825]

@@Core-Electronics The image became faster, but object recognition worsened. It draws the boundaries in different parts of the object. Thanks for your reply.

[@Core-Electronics]

I hadn't realised it would do that, without a doubt there is some code lines in there that when adjusted would fix up the boundary boxes.

[@diannevila8837]

@@Core-Electronics any update with this issue?

[@Jianned-arc]

oop last question sirs, can you use any type of type c and power supply cable for raspberry??

[@Core-Electronics]

You may be able to run a Pi with other power supplies but it's recommended to use the official Raspberry Pi Power Supply. They actually provide 5.1V to prevent issues from voltage drop that you might run into with a generic power supply.

[@jolly9833]

Hello, tried this on my raspberry pi 3b+. Im using camera module v2. I can't see the camwra in the raspberry pi configuration. Any ideas how to fix it? Or i can use a webcam as alternative? Pls i need your reply

Yes you can but you have to train your dataset. Watch some other tutorials on how to train dataset.

You definitely can, it will just run a little bit slower.

hey time ! i seem to encounter a problem while following your instructions on the "cmake -D CMAKE_BUILD_TYPE=RELEASE \ " i was getting the error : " CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases.

[@Core-Electronics]

Heyya mate, Sounds like a stray command line that didn't get typed in or using 'Bullseye' instead of 'Buster' Raspberry Pi OS. Jump to the comment section of the Article and that will have successful troubleshooting that will help you. If you still run into issues write up a message there with some screenshots of the problem and I'll make sure you get it running 😊

[@christopherlazo8485]

@@Core-Electronics Quick question, does that mean the OS needs to run this project is Raspbian 'Buster'? Not Bullseye? Would this also work for Ubuntu? I love your videos btw, I've been following it ever since I become a hobbyist for Rpi

[@Core-Electronics]

Definitely utilise 'Buster' Raspberry Pi OS for this guide. If you work hard at it you'll be able to get Machine Learnt Systems to work on Ubuntu, but the process will be different than what is outlined in the above video. And big thanks 😊 Raspberry Pi Single Board Computers are really rad.

[@mmshilleh]

Weird question, how did you manage to record the Raspberry Pi screen so smoothly. I am a fellow content creator not as big as you haha and I don't know any good Raspian software that does this

[@Core-Electronics]

Well spotted, there's no decent way to screen record a Pi internally without a terrible framerate. We run our Raspberry Pi through an Elgato capture card, just like you would capture gameplay footage from a console.
