Screen Capture with OpenCV and Python-2.7

by

That’s a solution code I’ve written using @Raoul tips.

I used PIL ImageGrab module to grab the printscreen frames.

import numpy as np
from PIL import ImageGrab
import cv2

while(True):
    printscreen_pil =  ImageGrab.grab()
    printscreen_numpy =   np.array(printscreen_pil.getdata(),dtype="uint8")\
    .reshape((printscreen_pil.size[1],printscreen_pil.size[0],3)) 
    cv2.imshow('window',printscreen_numpy)
    if cv2.waitKey(25) & 0xFF == ord('q'):
        cv2.destroyAllWindows()
        break
