Thanks a lot ! For all the people who look how to straight start a face recognition when the module is power on you just have to change in the code : typedef enum { START_RECOGNITION, START_STREAM, START_DETECT, SHOW_FACES, START_ENROLL, ENROLL_COMPLETE, DELETE_ALL, } en_fsm_state;
I think that this just means that when the browser connects you don't have to press the 'Access Control' button to start face recognition? You still have to connect to the browser so the websocket connection is active.
The best teacher ever. You did a amazing job! Everything worked for me perfectly. Thanks for share you knowledge 🙏🏻 Let me ask, do you have a sketch that works automatically when starting the controller?
Hello i got error like this "FaceDoorEntryESP32Cam:329:86: error: 'recognize_face_with_name' was not declared in this scope face_id_node *f = recognize_face_with_name(&st_face_list, out_res.face_id); ^ exit status 1 'face_id_name_list' was not declared in this scope " Can someone help me to fix that error pls
Excellent project. Working fine. Just I connected ESP32 and executed the sketch. I didn't change or create a new partition scheme. By default it has been set as Huge App in the IDE. I just connected an LED to test the recognition result. It works well.
Hi, does the face recognition also work offline (when no browser is connected)? Or is the ESP32 CAM Arduino support limited to the webserver feature? I've only found offline examples for ESP-IDF , but not for Arduino...
Hi, This one will work without being connected to a browser: robotzero.one/esp32-face-door-entry/ You need to be able to add the faces while using the browser but you could then run a cut down sketch to not use Wi-Fi at all once you have faces.
Congratulations, this project is really useful. You would have something with mqtt working together. Using mqtt I could easily work with Openhab. Thank you!
Can I know the method used in this project either it is Cascade Classifier method or any of this techniques Linear Binary Pattern, Eigenfaces, Fisherfaces?
everything running fine but when i opened webserver, no streaming is there. I am getting "Failed to get the frame on time! " this message on serial monitor.
Thanks for the great tutorial. What is the maximum number of faces that could be registered? Can we move the registry of faces to SD card so we can handle more users??
Very good ! It is the only video on esp32cam with such utility. It shows that there is a lot of knowledge . I don't know English and it is still perfect. Please I want to know what you mean when you say (IDF versions). You have to modify library code to detect life and not fool the system with photos? I have the ArduinoWebsokets library in version 0.5.3, esp32 1.0.6 and my Arduino ID 1.8.16 Greetings from Argentina.
Thanks! IDF is this docs.espressif.com/projects/esp-idf/en/latest/esp32/ To have liveness detection you need a second camera for a 3D image or an infrared for heat. Some systems might use face detection on frames in a video. Not possible at the moment with the ESP32 though.
That's awesome , but i have some questions 1-Can we add a virtual unlock button in the interface or whatever as a second way to unlock ? 2-Can we use 1 or 2 servo motors instead of that lock - i'd use 'em to power manual deadbolt lock- 3-Can we make use of the open Cv liveness detection
One and two are possible. You can code websockets for communication in both directions. Other tutorials on my blog might help with that. OpenCV doesn't work on the ESP32 AFAIK you would have to use the video stream on another device.
Hello, I need help. Maybe you can recommend me something concrete or at least make some suggestions in both the HW and SW parts. Any help is welcome. I need to set up a kind of surveillance/streaming system for a project at my school. I would very much like to do it with something like ESP32-EYE or ESP32-CAM. My intention is to stream (or as close as possible) on RU-vid or FB directly from the module. I am not sure if that is possible and how to do it. I am very tight on time, and I don't have much money for testing either. I know that you have a lot of experience and have tested many modules. Please, which ESP module/camera/software could I use for that? Thank you very much.
i have problem in my work, before, this esp32 cam worked well, but after several time. the esp32 cam can't work and the serial monitor showing "A Connection reset by peer" if you have solution please tell me . because i use this project for last exam in my college
i try connect with sit in front of my wifi router the result is same sir. I change the another browser and and use my hotspot in my phone still same. If i klik f12 in browser some problem has show in console. "Websocket connection to 'ws://192.168.1.7:82/'failed :could not decode a text frame as UTF-8". If i try with camerawebserver the esp32 cam worked fine.
Hi, thats a great video and i want to use it for my final project, what do i do if my arudino ide is version 2.x.x and above? Thank you vey much i hope for an answer
Hi! I managed to get it partially working. It detects at first then a few seconds later the ESP32 disconnects. Also, the output pin does not seem to output a signal. Are you using an original esp32? I'm using a clone from aliexpress (the Rx and Tx pins is reversed otherwise it won't upload the sketch).
@@webslinger2011 Normally RX on one device is connected to TX on the other. Might be a power issue, might be wifi. Does the CameraWebServer example work OK?
@@robotzeroone Other than the Tx and Rx pins were switched. Camera webserver works fine. It's when I try to activate a pin for the optocoupled relay that's when it resets/disconnects(happens even without anything connected to the output pin). Using your face recognition code.
I'm using a CP2102. I remember the FTDI I tried didn't work when I started with these cameras so I've not tried again since. Try changing the output pin. I found 2 and 12 worked. Do you have a card in the reader? Also if you look in the serial monitor and installing the ESP Exception Decoder might help.
I'm using the version 2.0.0 of the Arduino ESP32 hardware , what csv partition file have i to use ? With the csv file for the 1.0.5 version you provided, there is no streaming after connection to the web server.
@@robotzeroone Thanks for the information. I'll go back to the 1.05 version. By the way the camerawebserver example is working flawlessly with the 2.0.0 version.
Tutorial here for this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bIJoVyjTf7g.html&ab_channel=robotzero.one also on my blog linked from the video description.
First of all congrats for this great work! I'm facing an issue on this project...Everything was running perfect until the last couple of days i was no longer able to stream from the esp-32 cam, as a result it couldn't detect or recognize faces anymore. I updated the boards and libraries, i even tried it from different computer and browser but still the same. I still can browse into the web UI but it won't stream any image from the left window. I tested my esp32-cam board on other projects and it's fully functional. So, any thoughts what's causing this issue? Thanks!
Cheers for this guide, persistence was a big help. however it seems very laggy and slow, and is it possible to use without the browser connected? Don't want to have to have something logged into it all the time
It's slow because running the face recognition really taxes the ESP32 processor. This version you can disconnect - robotzero.one/esp-who-recognition-with-names/#comment-43712 Or you can use the version in the video to set up the faces and then this one - robotzero.one/esp32-face-door-entry/ without Wi-Fi to run it
Hey guys i need help for my project i want to create a door control with face recognition using esp32-cam, and also it can capture motion using motion sensor and send the picture using internet to the phone app...
Hello, I was wondering how I could go about drawing squares around peoples faces as I wish to repurpose this for a slightly different purpose. Any help would be appreciated!
I took out that code to try and make things less complicated and maybe run faster. I think the boxes are still there in some of the other tutorials on my blog.
I want to implement this project: "Design of Driver Awareness system depending on Eye and Face Feature and Discrimination" Can I use ESP32 instead of Raspberry Pi ? How do I program it and what do you use ? please reply
I just realized that I'm going to be missing pins to place my fingerprint sensor. This is a double authentication project that I want to do, incorporating fingerprint sensors and more facial recognition.
@@brianalmeida529 The problem has always been the pins. So many are used by the camera that there are very few available. I think my project will still work with the correct pins set.
@@robotzeroone What do you think of the wrover cam, will it be useful for my project? I have the following components: relay, fingerprint, that's all. And if there are more pins left over I want to use one or two buttons.
@@brianalmeida529 I'm not sure. If you can find a pin diagram you can see which pins are available and what interfaces they offer. This project was mine with most pins used so might give some help robotzero.one/esp32-cam-scene-analyzer/
Hello MR. Robot Zero, I really appreciate your work on this tutorial. I did the implementation as in your tutorial and everything works fine, faces are enrolled OK and faces are detected OK; However, if a new face (one that is not enrolled) is presented to the ESP32-CAM then sometimes the system detects it as one of the enrolled faces. Is this the bug that you mention at 9:16 of your video? Is there a fix to this problem?
The problem mentioned was with an earlier version of the ESP32 Hardware library. In 1.0.4 it's fixed. If you are finding it detects different people as the same there's a setting that can be changed but without looking into it I think it might be only available in the IDF version at the moment. Checkout FACE_REC_THRESHOLD here: github.com/espressif/esp-face/blob/master/face_recognition/README.md
@@robotzeroone THANKS for your response. I find a FACE_REC_THRESHOLD, in the fr_forward.h file. It looks like: #define FACE_REC_THRESHOLD 0.5 I changed this to #define FACE_REC_THRESHOLD 0.7 It is working now but I cannot yet confirm that reliability has improved. I am going to test during the next few days. Meantime, if you have any suggestion, please let me know.
Hai sir, I wonder if i can make the system recognize only 1 face in all faces in the db. For example like hardcode where face_id == 1, which system only recognize user where not the other. But it seem didnt work for the face_id. I also cant figure out how the enroll system save the face_id. Do you know what the return where I can make the == 1 to bind only 1 user? thank you..
Did you see the other tutorial here: robotzero.one/esp32-face-door-entry/ it's less complicated if you just want one face. Maybe the line if (matched_id >= 0) { could be changed to ==1?
Hi. Check out this video for connecting an LCD - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-j8lVFmjAARA.html You should be able to combine the code to do what you want.

Hello. Thanks for sharing your knowledge with us enthusiasts. I have a problem and would like your help. The scket ran fine, but in time to capture the image of no face detect in google chrome.

Dear sir one more question if i want to send user name to keep in Google Sheet (Log file or time Attendance) which Variable i can use to send it to google sheet
You want to grab the name from Websocket message? In the ws.onmessage method you need to do some sort of substring to get the name when the DOOR OPEN FOR... message comes in.
Dear Robotzero.one , Thank you for sharing thsi amazing project. You have done a Great Job ! Everythings works fine and you explanation was perfect. For what I have seen at the beginning of the video , you have the ESP 32 CAM installed right at door entry, but I am wondering how do you manage the browser page. After faces recognition, I would like to make it works as a stand alone device, without any PC connected that is needed (or I am wrong..) Is that possible ? Do you have some suggetion to do these SW modification ? Thanks a lot anyway for this project!
Cool. I'm glad it's working for you. This one will work without being connected to a browser: robotzero.one/esp32-face-door-entry/ The easiest way is to have one sketch to add faces and another you flash that doesn't need browser to be connected. Alternatively, you could probably do one sketch with a timeout so after five minutes it stops the websockets connection and just runs face recognition.
@@robotzeroone Thank you for your kindly reply. I will go for your suggestion to have two source codes. I tried the link you attached but it doesn't work for me. It show me the error : [ assertion "l->size == size" failed: .... /fr_flash.c ] and ESP is rebooting continuosly.... :-( Anyway thanks a lot for your support.
@@user-darkhan I am sorry but I don't have solved the problem. I will try again when I will have more time. I' ll let you know if having some good news.

Congratulations for the tutorial, I followed everything clearly explained, but loading the http page only the part of the controls is visible but the streaming image of the camera is not visible
Hi dear, My system gets connected to the IP. The interface is working but it doesn't store my face ID. Arduino serial monitor shows fr_flash: Not found with different error numbers on each attempt. ESP32 Cam tries to get samples but it is not saved. I shall be highly obliged if you please guide me where I am getting wrong. Awaiting your response. Kind regards.
Thank you very much sir for this wonderful video, but I have a question pls how can i change the code so that it will not capture one face with two different name, so that the system will prompt you that the face is already captured and has so and so name. Thanks you are my best mentor in IoT stuffs
Hello sir, wonderful tutorial. Just want to ask, can I extract the sample captured? will it be in picture format? if can, do I need to change into SD card partition or can use your created partition? sorry I a bit new in this area.
@@robotzeroone I see, so just to be clear. the partitions stored the face/user data but in other type like hex or byte is it? sorry I still dont know what is the partitions is.
@@said7176 The face data is a mathematical representation of the face. These are stored in the fr partition but I don't know how this is structured as a file system. You would have to look at the code in the Espressif IDF to see how it's done. Not really beginners level stuff.
thanks for the tutorial sir I want to know which program shows that the image is registered in flash memory? and I want to save the image on the SD memory card, how do I program it?
I don't really understand the first question. For the second you would have to combine this tutorial with one of the others on my blog where the image is saved to the SD card.
@@muchittt I don't know how you do that. I've seen other tutorials where the data is saved elsewhere but I don't have them to hand. It's probably quite complicated.
@@muchittt The face data is stored in a partition not the whole memory. I don't know how many.. Do some experiments. It will probably start to slow down before you run out of space.
Is it possible to run the recognition without opening the webpage? I changed the code already, so now the detection starts instant, when power ist connected. but before I have to open the webpage and I don't want that.
Check this tutorial for a version without the web browser. robotzero.one/esp32-face-door-entry/ Maybe you can load up the faces using the tutorial above and then switch to this one using the same faces.
Just in case there is any possibility of performing facial recognition, but without the need to access the web server?, that is, that the esp32cam works independently of a web server, that its function is to recognize the face and open the lock.
The image recognition is all done on the device. Computer is just to view and control the system. Here's a version that runs without a computer if you want something stand alone: robotzero.one/esp32-face-door-entry/
With the ESP32 it's going to be difficult. It's just not fast enough. There's this product (hard to find outside China though) - aliexpress.com/item/4000070597568.html?spm=a219c.12057483.0.0.5f1057ab3Yex4z that uses two cameras. Or with a PC (maybe Pi) something like this: www.pyimagesearch.com/2019/03/11/liveness-detection-with-opencv/ This one will probably be the best if you want to capture you face as you walk.
@@robotzeroone Yeah I think a PC would be the go. I want to connect other things in the house aswell, but the door system should be independent so it cant be hacked. The problem is I dont know how to code.
@Zed If you've not ever coded then this is jumping off into the deep end! The second link pyimagesearch has loads of tutorials but you'll probably need to learn some Python first. Loads of tutorials on RU-vid for that.
Sir, I mean great fan of yours. Above project is working good. Can you please modify the existing code so the esp32 cam keep working even without Android WiFi connectivity, as this system stops working when the mobile connection is lost for what ever reason. I mean the mobile user interface should only be used for face enrolment or to delete or add the users. With the existing system one needs to keep one Android phone to keep system up & running. An early response to my request will be highly appreciated. Kind regards
Here's a version that doesn't need a permanent connection. robotzero.one/esp32-face-door-entry/ I think there's also a version in the comments of this tutorial. Other tutorials that might be helpful: robotzero.one/esp32-camera-projects/
Hello sir, I am a newbie. I ran your project into the platform io process, and I encountered an undefined error on the operation function of face recognition (such as undefined reference to ''delete_face_id_in_flash_with_name'', etc...), how should I solve it? Also, do I need to put the two files fr_forward.c and fr_flash.c into the project? Because I saw from GitHub that they implemented the algorithm related to the face in the main program, and their .h files just declared and simply constructed them. How did you realize a series of functions such as recognition by only introducing their header files?
I can't really help because I've never used Platformio. This will only work with the version 1.0.4 and 1.0.5 of the ESP32 hardware libraries so I would start there.
@@robotzerooneOK, thanks. But why didn't you import the files fr_forward.c and fr_flash.c into the project? You just imported their .h files.Can you explain it to me a little bit if you can.

Because when I am doing functional operations, sometimes the webpage will get stuck, and then the board will restart the server.

Can you make another video like this where there is a second esp32 that activates the door lock when the one outside sees the face? This way someone can't just jump the relay from the outside.
Excellent video. I'm a Brazilian student and is i'm realizing a similar project. I would like to know what the names of the components and schematics used, because i only know the ESP 32 - CAM. Thanks!
