The Client wasĭeveloped and written by Andrew R. The include file, index_OCV_ColorTrack.h, the Client, is an intoduction of OpenCV.js to the ESP32 Camera environment. The program is split into two files: the OCV_ColorTrack_P.ino file containing the server program and the index_OCV_ColorTrack.h header file containing the client program (HTML, CSS and JavaScript with OpenCV.js).Ĭreate a new Arduino sketch called OCV_ColorTrack_P and copy the following code. the client program which runs on the Chrome browser.the server program which runs on the ESP32 Camera.ESP32-CAM Camera Boards: Pin and GPIOs Assignment Guide.For the pin assignment of the most popular boards, check this article: Make sure you know the pin assignment for the camera board you’re using. ESP32 Camera Dev Boards Review and Comparison (Best ESP32-CAM).For a comparison of the most popular cameras, you can refer to the next article: There are several ESP32 camera models out there.

This project is compatible with any ESP32 camera board that features an OV2640 camera.

Getting Started with VS Code and PlatformIO IDE for ESP32.

If you prefer to use VS Code + PlatformIO to program your board, you can follow the next tutorial to learn how to set up VS Code to work with the ESP32 boards.

Installing the ESP32 Board in Arduino IDE (Windows, Mac OS X, Linux).

So, you need the Arduino IDE installed as well as the ESP32 add-on: We’ll program the ESP32 board using Arduino IDE. OpenCV.js uses Emscripten, a LLVM-to-JavaScript compiler, to compile OpenCV functions for an API library which continues to grow.īefore proceeding with this project, make sure you follow the next pre-requisites.

ESP32-CAM Video Streaming and Face Recognition with Arduino IDEĪs described in, “ OpenCV.js is a JavaScript binding for a selected subset of OpenCV functions for the web platform”.

HTML, JavaScript, and other browser languages can take advantage of the extensive capabilities of ESP32 and its camera.įor those who have little or no experience with the ESP32 camera development boards can start with the following tutorial. The ESP32 can act as a server for a browser client and some models include a camera (for example, ESP32-CAM) which allows the client to view still or video pictures in the browser. This project/tutorial was created based on Andrew R. It is expected that this introduction will inspire additional OpenCV work with the ESP32 cameras.

This tutorial is by no means an exhaustive treatment of all that OpenCV can offer to ESP32 camera web servers.
