#ESP32CAM – Client Python 🐍 app to view WebServer photos πŸ“Έ

Hi !

Still learning with the ESP32 CAM board.

In today’s post the scenario is simple:

  • Create a client Python app to view remote photos from the ESP32 Cam Arduino device

This is a super lower quality photo, but hey, still good enough !

remote cam view with python and opencv

This is a super simple Python and OpenCV app.

import cv2
import numpy as np
import requests
url = "http://192.168.137.64/photo"
resp = requests.get(url, stream=True).raw
image = np.asarray(bytearray(resp.read()), dtype="uint8")
image = cv2.imdecode(image, cv2.IMREAD_COLOR)
# for testing
cv2.imshow('El Bruno - Remote ESP32 Cam image',image)
cv2.waitKey(0)
cv2.destroyAllWindows()

Full code available in my ESP32 Cam Demo repository.

Happy coding!
