import numpy as np
import cv2

cap = cv2.VideoCapture(0) # depending on the ZED ID

while(True):
    ret, frame = cap.read() # Capture SbS frames
    height, width = frame.shape[:2]
    left = frame[0:height,0:int(width*0.5)]

    # Display
    cv2.imshow('frame',left)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# When everything done, release the capture
cap.release()
