Using the documentation here, in section 4.4 the code is:
> import time import picamera import
> picamera.array import cv2
>
> with picamera.PiCamera() as camera:
> camera.start_preview()
> time.sleep(2)
> with picamera.array.PiRGBArray(camera) as
> stream:
> camera.capture(stream, format='bgr')
> # At this point the image is available as stream.array
> image = stream.array
As i understand it, this returns a numpy array to be read in openCV correct? My question is, how do I then open/access it to perform image processing on it in openCV?
