Raspberry Pi Object Detection Tutorial

[@calmrelaxangelicmusicph]

can you please make a tutorial on training your own data using google colab?

[@pratyushprajapati3908]

Thank you thank you thank you so much sir... 🙏🙏🌹🌹 I was doing this object detection using raspberry Pi for my final year project. Because of you I have learned a new thing and saved my thousands of rupees... Again thank you sir... 🙏🌹

[@SiriusFuenmayor]

really nice, it worked perfeclty with my raspberry pi3 model A. I was identified as a person an my face as a dog which is quite accurate.

[@robertoguerra5375]

NICE!!! Thank you for this video!!! At least we know that the raspberry has not become self-aware 😅

great video! thank you for teaching me how to implement object detection with my raspiberry 4.

Couldn't get it to load numpy for pi camera array . That pretty much stopped me right there is there some numpy package not mentioned here that must be installed first?.......it went on the third try wonder why ahhhhh the wonder years 😁

[@RETROGAME-FIX]

Hi sir your tutorial was the one that worked after 3 days of finding. I wanted to know how to shutdown the video feed? And how can i get the boundries around the object? And how can we make it a standalone live feed system to a android phone or tablet? I mean i dont have to put the commands all the time. Thank you.

hey this is so cool , i have a question ... what if i take your code(python) and trying to connect it with oher devices using C programming ?

[@charleslinquist]

I would like to perform object detection on a pi, and don't know if OpenCV or TensorFlow is the best tool. I want train the sw to detect any given object, and I also need an output that indicates the position, direction and (hopefully) speed of a moving object - a "follow me" or "follow a given object" feature. Any ideas or help would e appreciated. I'm a relative novice.

[@gasiboi3734]

Hi, i noticed that the video streaming of your Pi have 14 fps on it. I have tried installing Ultralytics YoloV8 on my Pi with the models also exported to NCNN. Now I also use a 720p webcam, however, my Pi can only give me 2fps max. I wonder if you were using a Google Coral USB Accelerator making it possible to reach 14fps for your stream. Did you? Or was it just the Raspberry Pi's power to deliver 14fps. Or does the brand of webcam even matters when it comes to fps? Would greatly appreciate a reply. Thanks. PS. I am using a Raspberry Pi 4B 8gb

I've been trying to attempt this tutorial. I'm using a 8 GB RAM raspberry pi on a 250GB SD card and the interface keeps on crashing on me. And I'm having storage issues due to the size of Tensor Flow and OpenCV. Any suggestions on how to mitigate this issue?

With that thumbnail you make it seem like this is real object detection with positioning information, while in reality this is only image classification. I don't think that you're misleading people on purpose, and many viewers seem to like the solution, but it would save future viewers time when they are looking specifically for object detection ...
