Capturing video from two cameras in OpenCV at once

Question

How do you capture video from two or more cameras at once (or nearly) with OpenCV, using the Python API?

I have three webcams, all capable of video streaming, locate

Answer 1

try to use this code... it worked as expected... this is for two cams,if you want more cams, just create the "VideoCapture()" objects...for example 3rd cam will have : cv2.VideoCapture(3) and corresponding code in the while loop

import cv2

frame0 = cv2.VideoCapture(1)
frame1 = cv2.VideoCapture(2)
while 1:

   ret0, img0 = frame0.read()
   ret1, img00 = frame1.read()
   img1 = cv2.resize(img0,(360,240))
   img2 = cv2.resize(img00,(360,240))
   if (frame0):
       cv2.imshow('img1',img1)
   if (frame1):
       cv2.imshow('img2',img2)

   k = cv2.waitKey(30) & 0xff
   if k == 27:
      break

frame0.release()
frame1.release()
cv2.destroyAllWindows()

ALL THE BEST !
