This project is all about Color Detection & Tracking with ESP32 CAM Module & OpenCV. Thus, we will be detecting any specific colors during live video streaming. Colour detection is necessary to recognize objects, it is also used as a tool in various image editing and drawing apps. This method is completely different from other ESP32-CAM Color Detection methods as we are not writing the color detection code for Microcontroller. Rather we will use our laptops for Python Code. This method makes the processing faster.

Later we will also share the values from our python code to ESP32-CAM using a Client-Server connection. The method of color detection used here is HSV or Hue Saturation Value conversion.

Here we have used the ESP32-CAM module, which is a small camera module with the ESP32-S chip. Besides the OV2640 camera and several GPIOs to connect peripherals, it also features a microSD card slot that can be useful to store images taken with the camera.

Initially, we will write the C Code for ESP32 CAM & then install Python and the required Python libraries. Later we will go through the Python Programming for using OpenCV. This is an essential tutorial as you will be able to use any sort of Image processing or Machine Learning on the live video without having to write it on Arduino IDE.

wonderful esp32 camera project 🥰 something different than the raspberry pi opencv design 🤔 thank you 🤩🙎‍♀🧚‍♂🐦🐬🌴

[Makerfabs]

Great video, and great 3d printed case!👏👏👏👏👏

[sudarshanseshadri]

This worked awesome, just one question, how can I send input from the python program back to the arduino to move a motor?? Please help! Thank you very much.

[kakikuda]

can you help me? I got this error

Error: <urlopen error [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond>

Hello how to eletronics, I am first on the comment... 😊😃

[nur_arifikhwan]

do you have any idea about how do after the cam detect specific color then it will send notification to user?

[febifebriansyah]

will it work to tracking a rat outdoor in the ricefield??

[vinayakdeshmukh]

it is showing Error compiling for board ESP32 Wrover Module.
please help

[reemashrestha]

when using reader.readtext() in the real time video, the stream is very slow. How can we solve this issue?

[kanakevin]

I got "Error compiling for board ESP32 Wrover Module" please how cam I solve it?

[nihadhpk]

What is the name of colour sensor used here?

[yoyopoonishere]

Great and clear video. But I only had 'CAMERA OK' but doesn't have the local IP address. How can I solve it? Thank you.

[pokednaful]

Hi. Can we connect it to arduino?
(Example : when the camera detect red colour, so the servo motor is turn on)

Or can we take the RGB color data from this camera and process the data in arduino?

Thankyou

[ArjunKohli]

code is not compiling : two many library used wifi.h, pls suggest how to solve

Error compilling for board AI Thing ESP32-CAM

[yayovera]

where can i find the code for a specific color, nice video

[hazqier]

I can't seem to run the esp32cam WifiCam.ino code. I got these errors:

In member function 'esp32cam::ResolutionList const':
error: 'camera_sensor_info_t' was not declared in this scope
error: 'info' was not declared in this scope
