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.
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 ✨✨
this was exactly the thing i was looking for. i will be buying things from their store as compensation!
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 :-)
Thank you very much for your work!
Just perfect, thanks a lot man!
And a really big thanks to you for explaining this so well😁😁
Thanks for sharing, this is really good and easy to follow
Hi Tim, I would like to ask how can I speed up the fps and speed up the recognition rate? Or do I need to use the lite version to speed up the speed?
To use a USB cam install fswebcam then change cv2.VideoCapture(0) to cv2.VideoCapture(0, cv2.CAP_V4L2) in the script
You're a life saviour. Thank you so much ❤
Amazing, Easy to follow, Comprehensive video for object detection. Gonna use this to turn my RC car into a autonomous vehicle. Thanks Tim, Keep up the great work :D
Oh man that sounds like an amazing project 😊! Definitely keep me posted on how it goes. The Forum is a great place for a worklog - forum.core-electronics.com.au/
brother i too am working on this project can you leave any leads i am sending you an email if you have time please reply
Hey man great video. Any chance you can cover how to use this same concept to detect anomalies instead? Rather than looking for specific objects expected to be there in the camera, the program learns the objects expected to be there and detects when an unusual object is found. Thanks.
Trust me . I just find everything I was looking for about my raspberry pi 🌹
Hey this is great, thanks for putting this together. Really easy to follow along as a beginner. Is there a tutorial that builds on this and allows you to connect a speaker to the raspi so that whenever a specific object is detected, it makes a specific noise? Would love to see it!
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. Here is a related guide on speakers - core-electronics.com.au/tutorials/how-to-use-speakers-and-amplifiers-with-your-project.html
@@Core-Electronics Supertar, thanks!
Hi Tim, the video was great btw do you know another dataset that i could use with this code, and can you explain how to train a new object to detect?
Thank you man! This was really helpful.
This is amazing ! this is soo very cool! Thank you for introducing me to coco!
cool, but what would it take to make this work with 60 fps (doing the image recognition in every frame and not lagging behind when things move fast)
Hi Tim, Thank you so much on this video for demonstrating how to use OpenCV with the Raspberry Pi. I am willing to follow along your process to install OpenCV and test it out. I am just wondering if OpenCV will run on the new Raspberry Pi OS
At this current stage I would recommend using the older 'Buster' OS with this guide. If you want to use Bullseye with machine scripts come check this guide on the OAK-D Lite - core-electronics.com.au/guides/raspberry-pi/oak-d-lite-raspberry-pi/
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.
You are a legend bro i have a question what if when it detects particular image in my case (garbage) it has to generate a gps location or it has to send the location of that point to another vehicle like you did to your servo motor
Hey tim! I successfully have managed to run this project in about an hour. I didn't compile opencv from source though. I installed it through pip but still got it working and its running pretty smooth. Hope you could change the opencv compiling part as it takes tooo long (took me 3 days and was still unsuccessful)and is unnecessary. Thank you I have used the raspberry 3b+ If you use raspberry pi 4, it could be much faster and smoother
If you can provide some more information I'd happily update the guides 😊 (Perhaps jump onto our core electronics forum and do a quick write up on your process)
Great video, thank you for sharing.
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?
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.
@@Core-Electronics thanks so much for this info. I have to get to work! I’m checking out the paper.
do you have any guides for using an ultra low light camera module such as Arducam B0333 camera module (Sony Starvis IMX462 sensor)
I have a imx219 apparently it will not work with opencv. Is there a way to use gstreamer to make it work in open cv?
Hello, great video but how do I get the coordinates of the tracked objects I am trying to build a robot that can identify and pick up objects, how would I find the coordinates
Great video, I just came up with an idea for a project using this. I have no experience with Pi's but basically it would be using a camera to detect a squirrel on a bird feeder and then playing some loud noise through a speaker. Would this be a difficult thing to do?
Sounds like an absolutely excellent idea that could definitely be implemented using this kind of Object Detection. We just had a new project posted on our website worth checking out all about using a Raspberry Pi to track Kangaroos and when it does it sends photos of them to a website server - core-electronics.com.au/projects/rooberry-pi
just dowload and extract this zip file. trust me
Does it work ?
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
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. Also in regards to AI detection to control a cursor on a Raspberry Pi come have a look at this video - kzhead.info/sun/m7CGlsd_goqeg4U/bejne.html
instead of raspberry pi 4 can we use a raspberry pi zero 2w if the speed doesn't matter to me?
Hi is there a way that then creates a log with all recognized animals/humans so data can be consumed ?
I got error Traceback (most recent call last): File "", line 35 cv2.putText(img,classNames[classId-1].upper(),(box[0] 10,box[1] 30), SyntaxError: invalid syntax What mean with this error, i already install cv2
This video helped a lot! 👍
Sweet! 😊
Lost two nights trying to run it on the latest OS! Use the previous one, it is mentioned in the article.
thank you, I was struggling with this and was utterly confused.
Excuse me, i need help please, tiny yolo is better to raspberry pi or normal yolo can be used?
Hi great videos! How do I add to the dataset, is there a file to add to or is it an adjustment in the code Thanks again
hi awesome video and great content, pls can I also get this same code to identify FIRE ? can you guide me to how i can do that. also can i get the trained dataset for Fire and how do i get the library into the folder
Amazing , thank you !
Our pleasure!😊😊
I wanted to apply this for feedback system for blind can it be adjusted on the cap
Can I run your project on MacBook if possible and in this case what kind of modifications to have with hardware please. Thanks
Hi tim, how to add gTTS in the program when the object is detected
great video! good for beginner. I want to get the name of the objects into a string and print it when object detected. Can you give me any tips or help to me? Thank you so much.
Cheers mate! In the main script underneath the line | result, objectInfo = getObjects(img,0.45,0.2) | is another line stating | #print(objectInfo) |. If you delete that | # | then save and run it again you will be printing the name of the identified object to the shell script. Hope that helps 😊
Hi this was a really great project and helped me a lot but can you help in how can we change the size of the box made around our object?
Size of the boxes tend to be based on the size of the detected object. But the Colour and Width of box can definitely be altered. Inside the code look for the section | if (draw): | Then below that the line | cv2.rectangle(img,box,color=(0,255,0),thickness=2) | By altering the (0,255,0) numbers you can change the colour of the box. By changing the thickness number you can have very thin lines or very bold lines. Font and other aesthetic changes can be done in the following lines.
@@Core-Electronics Thank you very much
Hey tim! Here's a question, Is the model trained by your coco generated by the yolo algorithm? This is related to the writing of my graduation thesis. I will be more grateful if you can provide more suggestions.
Sorry for getting to this so late. A lot can be learned here - cocodataset.org/ . Also there are a ton of research papers as people are unraveling this technology that are worth exploring (or adding to the bottom of a graduation thesis). Good luck mate!
@@Core-Electronics thanks so much！I believe that with your help I can get a high score.best wish！
Ty for a great video Where could i found library for specific stuff i need? I am looking for Cans, Bottles, glass bottles etc
Hello, did you ever find a library of the things you needed? I also need a library for specific items and was wondering if you found a good resource.
i did not made myself a model by training it using Roboflow @@kos309
Great video! I’m wondering if instead of the green rectangle with the name of the object, I can get the names of the objects into a string so I can print. I am trying to use a Text To Speech software so that whatever the object’s name, it is said out loud. Do you have any tips, help, or advice to give me?
Definitely something you can do! Theres a lot of great text to speech packages that will work with Raspberry Pi, Pico TTS is a great example of one. With a little bit code adjustment you'll be off to the races. Come make a forum post (link in description) on your idea and then we can give you a much better hand than I can here 😊
@Niseem Bhattacharya Did you figure out how to do that? I need help with it.
Hi Great video! can I use a usb webcam instead of the pi cam, is it just a case of changing the code
Will I be able to add an entire category to the list of objects to be displayed in real-time? So instead of saying ['horse'], could I possibly mention a broader category of ['animal'] in the objects parameter? If not, please do let me know the correct way to approach this.
The fastest way would be to just add a long list like ['horse', 'dog', 'elephant'] etc. If you check the full-write up I do something very similar there.
For anyone it might help out later. I followed the commands on the guide verbatim and was having issues on the, "cmake -D CMAKE_BUILD_TYPE=RELEASE \" and 4 following commands that are all grouped together. I was using, "Right click highlighted text - copy, from the web page and CTRL+Shift+V paste to Terminal to input commands. And that worked great for most of the commands but doesn't appear to work for that last paragraph. I had to manually type it in myself in order for it to work correctly. Tim if you do read this, first of all thanks. But I am a tad lost on exactly when to change back the CONF_SWAPSIZE to 100. I assume after the installation is fully complete but to some of us noobs, its a bit unclear I guess. Also, don't know exactly why, but it says that, "sudo pip3 install numpy" already had its bits installed to Buster so it "might" be redundant. Unless its more of a full proof guild for other versions of the OS. Finally able to finish up my project! Once this finishes installing... :P
Cheers for this write up mate 🙂 I'll legit jump into the guide and make it a little clearer when to swap back the CONF_SWAPSIZE. I'll make it more similar to what I have in my Face Recognition written up guide. My intention is to 'Noob proof' it as best as I can so everyone can have Open-Source Machine learned systems in the palm of their hands that they've created themselves. Very glad you now have it all up and running too!
@@Core-Electronics I didn't think to check your guild on the other OpenCV videos. I'll go do that now. Finally have the next 2 days off so I can fully jump into it. I got past this issue, but now when I run the script its having issues no one else in the forums had. I assume this was due to some issues I may have made when trying to get the multi line command working. Idk so lost with all of this lol. I'm good with Arduino, but Raz Pi, Linux, console commands and scripts vs coding. So much to learn at once. You are such a huge help while lost and overwhelmed in this new little world.
very good video and explanations are well detailed. please I have a project that consists of detecting paper your technique works with other objects but does not work with paper. I don't know if it's possible to teach the system to recognize paper. Thank you
Edge Impulse is your friend here - www.edgeimpulse.com/ This will let you customise already created AI systems like the CoCo Library. Stepping through this system you will be able to modify CoCo library to recognise paper 😊

Thanks for the tutorial. Can you maybe show how to implement a new library? I want it to just detect If there is an animal, the kind doesnt matter.
I've been learning more about this recently. A great way to create custom libraries that a Raspberry Pi can then implement is through Edge Impulse. With this you will be able to train and expand the amount of Animals that default COCO library comes with. Tutorials on this hopefully soon. 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?
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/

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.
Good to know, will be buying one today. Thanks@@Core-Electronics
Nicely explain. Please do I apply this on new dataset different from this?
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.

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.)
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.
@@Core-Electronics The image became faster, but object recognition worsened. It draws the boundaries in different parts of the object. Thanks for your reply.
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.
@@Core-Electronics any update with this issue?
oop last question sirs, can you use any type of type c and power supply cable for raspberry??
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.
Hi, Tim. I am using your source for my object detection project! Thank you so much! But, I have a question about delay. So, there seems like about 10 seconds delay in real-time. Is there any way to reduce that delay, such as “decreasing frame rate”, or “reducing the number of images read every second”? I am trying to find where I can adjust those in the code, but it seems hard to do so. Thank you so much!
Awesome! 10 seconds is a very long time though, what hardware are you using? Software wise by limiting the objects it searching for I have found it to increase speed, also deep in code you can find locations to lower camera resolution which will help too.
@@Core-Electronics Thank you for your reply! So, I am using "Raspberry Pi" and "Logitech C930e 1080P HD Video Webcam" for camera. I tried limiting the objects it searching, but it didn't help because it anyways detected objects even though the bounding boxes are not displayed in the video. And I think I am using 640 x 480 resolution, then do I just manually change it to smaller scale? except those two methods above (limiting objects it searching for, lowering camera resolution), are there any other ways to reduce the delay time? such as "changing FRAME RATE?" or "reducing the number images per second"? Thank you so much for your help. -Kyung
Hi did you succeed in lowering your delay?
@@xyliusdominicibayan6215 Hey, I couldn’t reduce delay. My project was done last year, but I just used my laptop instead of Raspberry Pi. If I had more time to fix it, I would have tried to lower the delay using Pi.
@@kyungpark5258 did you find a solution to your problem? I have the same problem also
Hello I'm verry happy to see this tuto Thank for help Is it possible to detect drugs or pills ?
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/
Can you do this with your own dataset and if so how? Need it for a school project. Thank you to whoever answers.
Yes you can but you have to train your dataset. Watch some other tutorials on how to train dataset.
@@arafatsiam4060 Will a dataset made from TensorFlow lite work? Or is there a different one compatible with the program?
how to detect waste like lays packets ?
Hii I'm having some problem in my raspberry pi 4 model B while update & upgrade it shows some errors I'm. Going to do object detection on raspberry pi project on my engineering college I have to compete the project before 28 th April so please kindly reply to my comment and pls help me 🙏
Heyya mate, if you are running into errors come check the comment section on the full write up as there is a lot of successful troubleshooting to learn from and you can post some screenshots of your errors there. I'll help get your system running proper 😊
can this work without the raspberry pie just using pycharm
Can you do this with a Chromebook?
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
You have the right OS? Buster?
Hi, How can I run the object detection even without connection to laptop or manually running the code.
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 - kzhead.info/sun/pamrcbOieHWKaa8/bejne.html) or you could run the code remotely using your phone (check here - core-electronics.com.au/tutorials/raspcontrol-raspberry-pi.html)
