TWe're happy to have you! You should check out our Office Hours and Engineering Hour sessions on Friday and Sunday, respectively. We also have some cool demos coming out. And if you're interested in anything you don't see or have suggestions on how we can improve, we're all ears. Just let us know!
WGood morning,I have a project in which I am using Android application for object detection
Currently my phone camera opens when I open the application and it starts detecting the objects
But I want to integrate the esp32 cam with android so that esp32 video stream come to android and should be shown at phone's screen
Basically it uses phone camera for object detection now it should use esp32 cam
Can anyone help?

UYou can run a Webserver on a ESP32 CAM Module. And access it from Android App which can be made by using simple MIT App Inventor. So that the Mobile App will access a video stream over HTTP as a client. Also, you can add additional capabilities like the object detection algorithm running on ESP32 to acces camera stream connected to it.
AWich app you are using, it mabe has a sitting to change cam source and his choosing phone cam us default

GI got invite from Shakila and just checking what it is about
BI haven't worked with Android applications before, but I tried connecting the ESP32-CAM. I used the example called 'CameraWebServer,' which gave me an address. I put this address into my Python script, and it worked. I'm not sure if I answered your question correctly.
B@wafa_athmani Have you tried calibrating the ESP32-CAM? I ask because I need its parameters for my project. I've already tried, but the results aren't accurate.
WActually i tried your solution by using flask library and then used kodular WebViewer، i completely changed the app but works very nicely and smoothly thank you for the idea
BThe ESP32-CAM can only capture frames, it does not support functionalities such as opencv
UTo use
OpenCV inference (ML)import time
import esp32_camera # Replace with your ESP32-CAM library
camera = esp32_camera.Camera()
camera.set_resolution((320, 240)) # Adjust as needed
camera.capture_frame()
img_data = camera.frame
format (assuming RGB format)
img = Image.frombytes('RGB', camera.frame.shape[:2], img_data)
img.save('f3.png', 'PNG')
camera.deinit()
print("Image captured and saved as f3.png!")
This is the code i used to take a pic , i hope it would help you

BRPi is too expensive compared to the ESP32CAM. Can I still use it for capturing frames? I plan to process the data on my laptop and then send it to the ESP32 via WiFi
BAnd my system doesn't necessarily need to be real-time strict
BI've already tried to calibrate the camera. I need the parameters you obtained to compare them with mine.
S@Q Welcome! Can you let us know a bit about your technical background, what brings you to DevHeads, and what you're looking to learn/contribute?!
UYes, most of my experience is with RPi and its camera modules. But I'm not sure about ESP32 CAM and its limitations at this moment especially, with capturing frames.

CGood evening guys,I’m unable to get my TFT ILI9488 480x320 screen to work with the TFT_eSPI.h library
!thank you for your help.

4good afternoon
can i use esp32 cam with raspberry pi to detect object ?
can i use esp32 cam with raspberry pi to detect object ?
AYes, you can use an ESP32-CAM with a Raspberry Pi to detect objects. You can use the ESP32-CAM to capture images or video of the scene, then transfer that data to the Raspberry Pi for object detection using software libraries like OpenCV or TensorFlow.
BGuys, who has tried to calibrate an ESP32-CAM? I've tried it but didn't achieve good results. Please, if anyone has tried it, could you send me the parameters of the camera?
Wme not. still not got any further with what i tryed to do
Bwhat are you planning to do with ESP32
Wjust some audio, input and vouice controlled
DHi All, right now i am using PIC32 microcontroller should i convert to stm32 since microchip IDE and pickit is really suck and the stm32 price is much more cheaper

THope you're making good progress, Kristof! Give us some good news!
YHi team, What is the maximum data size that can be sent using MQTT on an ESP32, and is this task blocking?
