@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.

camera.capture_frame()

img_data = camera.frame

img = Image.frombytes('RGB', camera.frame.shape[:2], img_data)

img.save('f3.png', 'PNG')

camera.deinit()

RPi 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

I've already tried to calibrate the camera. I need the parameters you obtained to compare them with mine.

Yes, 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.

can i use esp32 cam with raspberry pi to detect object ?

aymen ammari•3/29/24, 12:23 AM

Yes, 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.

BenOP•3/29/24, 2:32 AM

Guys, 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?
