ESP-WHO [中文]
ESP-WHO is an image processing development platform based on Espressif chips. It contains development examples that may be applied in practical applications.
ESP-WHO provides examples such as Human Face Detection, Human Face Recognition, Cat Face Detection, Gesture Recognition, etc. You can develop a variety of practical applications based on these examples. ESP-WHO runs on ESP-IDF. ESP-DL provides rich deep learning related interfaces for ESP-WHO, which can be implemented with various peripherals to realize many interesting applications.
We recommend novice developers to use the development boards designed by Espressif. The examples provided by ESP-WHO are developed based on the following Espressif development board, and the corresponding relationships between the development boards and SoC are shown in the table below.
| SoC | ESP32 | ESP32-S2 | ESP32-S3 |
|---|---|---|---|
| Development Board | ESP-EYE | ESP32-S2-Kaluga-1 | ESP-S3-EYE |
Using a development board not mentioned in the table above, configure pins assigned to peripherals manually, such as camera, LCD, and buttons.
ESP-WHO runs on ESP-IDF release/v5.0 branch . For details on getting ESP-IDF, please refer to ESP-IDF Programming Guide.
If you use ESP-IDF release/v4.4, please checkout the ESP-WHO branch to the idfv4.4.
Run the following commands in your terminal to download ESP-WHO:
git clone --recursive https://github.com/espressif/esp-who.gitRemember to use
git submodule update --recursive --initto pull and update submodules of ESP-WHO.
All examples of ESP-WHO are stored in examples folder. Structure of this folder is shown below:

Open the terminal and go to any folder that stores examples (e.g. examples/human_face_detection/lcd). Run the following command to set the target chip:
idf.py set-target [SoC]Replace [SoC] with your target chip, e.g. esp32, esp32s2, esp32s3.
NOTE: we implement examples of target chip esp32s3 with ESP32-S3-EYE by defaults. So that flash and monitor are through USB. If you are using other board, please confirm which method you will use first,
- If by USB, just keep it in defaults,
- If by UART, set it in menuconfig.
If not using the Espressif development boards mentioned in Hardware, configure the camera pins manually. Enter idf.py menuconfig in the terminal and click (Top) -> Component config -> ESP-WHO Configuration to enter the ESP-WHO configuration interface, as shown below:
Click Camera Configuration to select the pin configuration of the camera according to the development board you use, as shown in the following figure:
If the board you are using is not shown in the figure above, please select Custom Camera Pinout and configure the corresponding pins correctly, as shown in the following figure:
If the output of example is displayed on web server, click Wi-Fi Configuration to configure Wi-Fi password and other parameters, as shown in the following figure:
Flash the program and launch IDF Monitor:
idf.py flash monitorThe default binaries for each development board are stored in the folder default_bin. You can use Flash Download Tool (https://www.espressif.com/en/support/download/other-tools) to flash binaries.
