The ESP32-CAM can only capture frames, it does not support functionalities such as opencv
The ESP32-CAM can only capture frames, it does not support functionalities such as opencv
UTo use
OpenCV and runing inference (ML). I suggest using RPi with HQ Camera module
Wimport 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.
LI plan to visit the Embedded World expo in Nuremberg on April 9th, 2024. If you're interested in chatting about IoT-related topics, don't hesitate to reach out.
Let's connect and exchange ideas!

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

DIs this application note applicable to esp32-s3 freertos ?
M@kingrom , yes it is applicable
KHi guys. I'm still in China. Won't be available for the meeting
S@diamonddog427 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?!
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?
