ESP32-CAM | ESP32 Camera Module with Face Recognition

ES32-CAM-esp-32-camera-module.jpg

A step by step guide to setting up the Ai-Thinker ESP32-CAM with Espressif’s ESP32 development environment and the ESP-WHO libraries for face detection and recognition.

With this module you get face detection for ~ $7!  They have them on AliExpress here.

The AI-Thinker ESP32-CAM module features an ESP32-S chip, an OV2640 camera and a microSD card slot. The software needs to be compiled and uploaded using the Espressif development environment.

Follow the steps below to download and install everything you need to develop on the ESP32 including packages for the ESP-IDF and the ESP32 toolchain. If you prefer to use the Arduino IDE (it’s a lot easier to set up the web server demo) there’s another tutorial here: ESP32-CAM using Arduino IDE

ESP32 IDF Development Environment

Download the all-in-one toolchain and msys32 environment from here:
https://dl.espressif.com/dl/esp32_win32_msys2_environment_and_toolchain-20181001.zip
Create a new directory in your C drive called msys32.
Unzip the contents of download to this new directory.
Navigate to C:\msys32\ and double-click mingw32.exe to open a terminal.
In this terminal type or paste each command below:

mkdir -p ~/esp
cd ~/esp
git clone -b v3.3.1 --recursive https://github.com/espressif/esp-idf.git

If you look in c:\msys32\home\**yourusername**\esp\ you will see all the APIs and libraries for the ESP32 have been installed.

A user profile script needs to be added so projects will build without the path to these files having to be entered every time.

Find the path to the ESP-IDF. Following this tutorial it will be C:\msys32\home\**yourusername**\esp\esp-idf\
Create a new file named export_idf_path.sh in C:/msys32/etc/profile.d/
Open it in Notepad and add the following line to the new export_idf_path.sh file replacing the IDF_PATH with your own. Check you are using forward slashes.

export IDF_PATH="C:/msys32/home/**yourusername**/esp/esp-idf"

Save and close this new file.

Close the MSYS2 terminal window and then double click mingw32.exe to  open it again. Check if IDF_PATH is set by typing:

printenv IDF_PATH

To complete set up, paste the following commands in the MSYS2 terminal window

pacman -S mingw-w64-i686-python2-cryptography
python2.7 -m pip install --user -r  C:/msys32/home/**yourusername**/esp/esp-idf/requirements.txt

The ESP32 development environment is now set up.

ESP-WHO Face Detection and Recognition Libraries

To set up the face detection and recognition libraries and demos, type or paste the following commands in the MSYS2 terminal window

cd ~
git clone --recursive https://github.com/espressif/esp-who.git

If you look in c:\msys32\home\**yourusername**\esp-who\ you will see the ESP-WHO libraries and examples have been installed.

Connections

The ESP32-CAM doesn’t come with a USB connector so you need either a CP2102 or a FT232RL USB to TTL Serial Converter to connect it to your PC. When using WiFi the ESP32 can use more current than is supplied via USB through these devices resulting in the module crashing and rebooting. I found the top device worked fine (I bought it here) but the FT232RL wouldn’t work without a separate supply to the 5V pin. If you use a FT232 with 5v and 3.3v, set the voltage jumper to 3.3v so the serial connections are at 3.3v. You might be able to use the 5V from the side of the board to power the 5v pin on the camera.

USB to ESP32-CAM Wiring Diagram

Wire the module according to the diagram above and plug into your PC. The green connection should be connected when flashing the module and disconnected when running.

Open Device Manager and make a note of the port number of the serial converter:

COM Port

Camera Web Server Example

In the MSYS2 terminal window type or paste the following:

cd ~/esp-who/examples/single_chip/camera_web_server/
make menuconfig

In the window that opens you need to change the following settings

Serial flasher config —> Default serial port (Change to the port number shown in Device Manager – ie COM3)
Camera Web Server —> WiFi Settings —> (Add your WiFi SSID and Password)
Camera Web Server —> Camera Pins —> Select Camera Pinout —> (Select ESP32-CAM by AI-Thinker)
Component config —> ESP32-specific —> SPI Ram config —> Type of SPI RAM chip (Select Auto-detect)

Save the configuration.

In the terminal window, type:

make flash

If you get an error that the device fails to connect. Check that the IO0 pin (green in the diagram) is connected to GRD and press the reset button under the module and try again.

When the device has completed flashing. Unplug IO0 from GND and type:

make monitor

Press the reset button on the ESP32-CAM and watch the start up sequence in the terminal.

Look for the IP address the ESP32 has been given on your network camera wifi where it outputs got ip:xxx.xxx.xxx.xxx

Connected to WiFi

Type that IP address into your browser. You should be able to see a GUI on the left where you can control elements of the camera, set face detection and face recognition. Click Get Still to take a photo. Click Start Stream to see a video stream from the camera.

ESP-WHO GUI

It’s worth checking the jumper next to the IPEX connector on the bottom of the board to make sure it’s set for the internal aerial otherwise you may see low frame-rates and poor reception.

    This was extremely helpful. Thanks! Is it possible to save an image to the built-in SD card? I’ve been trying to get the card to work but so far the ESP32-CAM won’t recognize it.

    1. WordBot says:

      Here’s a start – https://github.com/raphaelbs/esp32-cam-ai-thinker/tree/master/examples/sd_jpg this is for the Espressif IDF. I’ve not tried it myself.

      1. WordBot says:

        This tutorial has a section for saving to the SD card – https://robotzero.one/time-lapse-esp32-cameras/

  3. Gautham says:

    Nice tutorial , thanks for sharing ,
    Is it possible to handle face recognition , movement detection and other task like registering the name of the face recognized in cloud with this , are all these possible with the 4MB RAM ?

    1. WordBot says:

      Not sure about movement detection with the current library but face detection and sending the name of the person to the cloud would be possible with some work.

      EDIT: Check this page for tutorials for sending names via POST or Blynk: https://robotzero.one/esp32-camera-projects/

    Hi,
    thanks for the details on getting this up an running.
    I am only get MJPG: 10003B 1324ms (0.8fps), AVG: 2156ms (0.5fps), 0+0+0+0=0 0 for qVGA where I see some people saying the get 30fps + , any ideas why my frame rate would be so bad? I had a look at the timings and the initial connect is 261ms, waiting TTFB is 544ms and download is 1.30s. I have no issues streaming and have good download speeds with everything else vir wifi.

    Regards
    David.

    hi,
    how to solve python dependencies error .because of this error i could not able to flash the unit.
    can anyone send the link to download this tool chain version (crosstool-ng-1.22.0-80-g6c4433a). i need in both 32 and 64 bit.

    1. WordBot says:

    Which kit is this ESP32 cam comes up on from these three?
    ESP32 DevKitC
    ESP-WROVER-KIT
    ESP32-PICO-KIT

    1. WordBot says:

      It’s the Ai-Thinker. You should see it as an option when you make menuconfig. It’s here in the code: https://github.com/espressif/esp-who/blob/master/examples/single_chip/camera_web_server/main/include/app_camera.h

  10. Rockman says:

    Serial flasher config —> Default serial port (Change to the port number shown in Device Manager – ie COM3)

    This changes cannot able to do in UBUNTU 16.04 .How to to do this please comment

  11. sunil says:

    HI @WordBot,
    i can able to take a still with the camera but face detection and face reorganization is not happening, Do any one know for what reason it is not happening.please help me out to solve this issue.

    1. WordBot says:

      When you turn Face Detection on and press Start Stream do you get a green box around your face? It has to be the right way up. Here’s a video: https://www.youtube.com/watch?v=gZgGniTLCiU

  12. ehatzidimi says:

    is it easy to activate a pin out when it recognize a registered face?

    1. WordBot says:

      There’s some examples here: https://github.com/espressif/esp-who/tree/master/examples/single_chip I imagine you could add a line of code to set a pin high or low when a face is recognised to one of the examples.

      UPDATE: In the Arduino IDE this example sets a pin high: https://robotzero.one/esp32-face-door-entry/

  13. alxexandru says:

    very nice and cheap project !
    can we do with this face recognition to say “hello John” , if John face is on front of camera?

  14. Thomas Kjeldsen says:

    this guide……. lack information….
    my machine dont know git… ohhh you need to install it… nice to know….
    the msys32 basic respond is unknown command

    1. WordBot says:

      You need to install msys32 first and then run through the instructions using this.

  15. David says:

    hi Robotzero,

    thanks for using time to teach us :-). Do you had any idea what happen here? My issue is documented here:

    https://github.com/espressif/esp-idf/issues/3730 (make flash failed)

    esp-who: newest one, download from today
    esp-idf: 3.2.2
    msys64: newest one, download from today
    cat c:\Users\tuan\Documents\Arduino\esp-who\esp-idf\tools\toolchain_versions.mk
    SUPPORTED_TOOLCHAIN_COMMIT_DESC = crosstool-ng-1.22.0-80-g6c4433a
    SUPPORTED_TOOLCHAIN_GCC_VERSIONS = 5.2.0
    CURRENT_TOOLCHAIN_COMMIT_DESC = crosstool-ng-1.22.0-80-g6c4433a
    CURRENT_TOOLCHAIN_COMMIT_DESC_SHORT = 1.22.0-80-g6c4433a
    CURRENT_TOOLCHAIN_GCC_VERSION = 5.2.0

    # xtensa-esp32-elf-gcc –version (msys64: mingw32.exe )
    xtensa-esp32-elf-gcc.exe (crosstool-NG esp32-2019r1) 8.2.0

    so it seem the toolchain from msys64 is newer than the one inside “ESP-WHO” (https://github.com/espressif/esp-who.git)

    1. WordBot says:

      I’m not sure what you’ve done but I would delete everything and then follow this step by step: https://robotzero.one/esp32-camera-module/ I’ve not tested that it still works for a few months but it should be OK.

  16. David says:

    Thanks, I did follow your step 100% 🙂 and recheck it many times.
    I am afraid it will not help due to the new msys2’s toolchain is newer than the one from ESP-WHO git, beside some other thing is missing as well. As one wrote on git, all that continuously changes and dependency (esp32 needs msys2) make a new guide/tip 2 decade old as soon you public it.
    what i had learn from it : from now on I will save the zip and share the versions to the user so they know what expected them.
    msys2: toolchain= crosstool-NG esp32-2019r1, gcc: 8.2.0
    “ESP Who” expect: toolchian=crosstool-ng-1.22.0-80-g6c4433a ; gcc:5.2 (cat c:\Users\tuan\Documents\Arduino\esp-who\esp-idf\tools\toolchain_versions.mk)

    I hope the espressif will help to sove out.

  17. WordBot says:

    I just ran through the tutorial and apart from one restart of mingw32 (think I lost internet) and having to run an extra command (now added to the tutorial)…

    C:/msys32/mingw32/bin/python.exe -m pip install –user -r C:/msys32/home/**yourusername**/esp/esp-idf/requirements.txt

    it all worked fine. You just download the 32bit version of MYSYS and paste all the commands into the MYSYS terminal. It should download and install everything for you.

  18. David says:

    hi robotzero
    Thanks for your patience, 2 thing I did wrong: i use msys2 64bit and i reused the esp-idf inside esp-who.
    git clone –recursive https://github.com/espressif/esp-idf.git
    that esp-idf has the correct toolchain, which support by d:\msys32\opt\xtensa-esp32-elf\
    nb: i compare the xtensa directory at 32bit & 64bit, they are similar. so it will be ok to use msys2 64bit as well I guess (didnt try this, the “make flash” take almost 15min)

    c:\Users\tuan\Documents\Arduino\esp\esp-idf\tools\toolchain_versions.mk
    SUPPORTED_TOOLCHAIN_COMMIT_DESC = esp32-2019r1
    SUPPORTED_TOOLCHAIN_GCC_VERSIONS = 8.2.0

    CURRENT_TOOLCHAIN_COMMIT_DESC = esp32-2019r1
    CURRENT_TOOLCHAIN_COMMIT_DESC_SHORT = esp32-2019r1
    CURRENT_TOOLCHAIN_GCC_VERSION = 8.2.0

    Nice too know how to use “make” for the code, I did tried the same code on arduino IDE (I choose the board “AI thinker esp32 CAM”), it is faster (took around 2min)
    I exclude those folders in my anti virus AVG to get speed up the arduino compile.
    c:\Users\tuan\AppData\Local\Arduino15\
    c:\Users\tuan\Documents\Arduino
    d:\program files\arduino

    I think too much I think 🙂 , i should just use COM16 (my usb-> serial use port 16) in “make menuconfig” as you wrote in the guide. Another 15min need to wait…..

    Anyway 1 cup of black coffee is sent with UPS 🙂 …thanks you for your help & well done.
    I will let the guy at ExpressIF know, so they can close the ticket. (they use an old toolchain inside esp-who)

    1. WordBot says:

      The IDF version probably has more recent code for the webserver example. Arduino setup is muuuuch easier! At the moment the face detection doesn’t work in the current version of ESP32 library for Arduino IDE.

    1. WordBot says:

      Arduino code is C (sort of). Most of the libraries from the IDF examples https://github.com/espressif/esp-who/tree/master/examples/single_chip will work in the Arduino IDE. Nearly all of the tutorials I’ve written recently use code taken from them because it will also compile with the Arduino IDE. You have to make changes to fit the Arduino programming style such as using void setup() and void loop(). More reading: https://www.esp32.com/viewtopic.php?t=5669

  21. Danny says:

    even though my dev. environment is FreeBSD, it went without a stich!!
    at the moment the only problem I see is that there are some horizontal lines
    when streaming, any idea what it can be?

    1. WordBot says:

      Probably the hardware itself. The ESP32-CAM isn’t that well designed and suffers from heat problems. I’ve had to replace a couple of the cameras on mine.

  22. danny says:

    I just tried it on a ttgo-camera-plus, and no horizontal lines!
    great work!
    you might want to add it to the list of supported.

  23. ed says:

    I found the face recognition to only work with the previous ESP32 core, nor with core 1.0.2

    1. WordBot says:

      Yeah the newest Arduino IDE ESP32 hardware libraries aren’t working at the moment: https://github.com/espressif/arduino-esp32/issues/2731

      Hi, I don’t know what the problem is but I wouldn’t mix and match tutorials. It should work with my tutorial but it’s possible something has changed in the IDF.

  25. BitFlip says:

    Sorry for the mess in the last post.

    I went back and went through your steps above.
    every time I get to running the script file, it goes through and installs or upgrades and at the end it says successful.
    Except for some 64 bit cryptography file that it points out. mine is a 32 bit machine so i ignore it.
    I then go into the esp directory and try the git clone command and get this error.

    [email protected] MINGW32 ~/esp
    $ git clone –recursive https://github.com/espressif/esp-idf.git
    -bash: git: command not found

    any ideas ?

    1. WordBot says:

      Looks like you don’t have git installed – https://git-scm.com/downloads

  26. BitFlip says:

    I thought maybe that was it too. I installed it and rebooted and it still does it. I tried installing it at C:/ and a few other places with no luck. Thats why i reinstalled Windows 10 again and so I could start over clean with your tutorial
    I thought it was something to due with environment variables but I don’t know enough about it to know what to to do.
    I tried going to the C:/msys32/home/rtros/esp directory in windows file explorer and doing a right click and selecting Git Bash Here option and it shows a man page about options and such so it seems to recognize Git commands.
    I can do git –version and it returns git version 2.25.0.windows.1
    The shell window is titled ==> [email protected] MINGw32 /c/msys32/home/rtros/esp (where rtros is the user directory)
    Do you know if the the git clone commands in your tutorial will work correctly in this Git Bash shell?

    By the way, I love all the tutorials you have on your page. They are very detailed and understandable.
    I have tried the two boards i have with the Ai-Thinker ESP32-CAM in the Arduino IDE tutorial. They both worked right away with the USB programmer you pointed to. Excellent!
    i meant to ask you last time, Is your Bitcoin address still usable?

    Thanks

    I closed the shell and rebooted the machine.
    then I tried the Git version again……………………………………………………………………………………………………………………..

    Sorry for all the text pasted. I thought maybe it would help to see what was the output was.
    Did I miss something in the process ?

      I’ll try and make a video tomorrow of the install process on a fresh install of Windows 10 to make sure it still works and so you can see the steps I took.

      Hi, I’ve been trying to fix the tutorial today but it seems that the windows_install_prerequisites.sh isn’t installing git and whole lot of other modules. I tried installing the missing things manually but it didn’t work in the end. I wanted to make it all work with python3 because 2 has been discontinued. So.. I’ve changed the tutorial to do it the Espressif way. It seems to work like this now and I’ve made a video which I’ll upload tomorrow.

      Possibly the problem you had before would have been fixed with adding this line:
      pacman -S mingw-w64-i686-python2-cryptography
      before this one:
      python2.7 -m pip install –user -r C:/msys32/home/**yourusername**/esp/esp-idf/requirements.txt

      EDIT: Here’s the video – https://vimeo.com/385965036
