PiCamera and continuous_capture with python and raspberry pi

I believe you are looking for capture_continuous.

Heres the general process:

• Import the necessary packages
• Pause to allow the camera to warm up
• Iterate through the camera frames
  • Capture and show the frame

from picamera.array import PiRGBArray
from picamera import PiCamera
import time
import cv2

# initialize the camera and grab a reference to the raw camera capture
camera = PiCamera()
camera.resolution = (640, 480)
camera.framerate = 32
rawCapture = PiRGBArray(camera, size=(640, 480))

# allow the camera to warmup
time.sleep(0.1)

# capture frames from the camera
for frame in camera.capture_continuous(rawCapture, format=bgr, use_video_port=True):
    image = frame.array

    # show the frame
    cv2.imshow(Frame, image)
    key = cv2.waitKey(1) & 0xFF

    # clear the stream in preparation for the next frame
    rawCapture.truncate(0)

    # if the `q` key was pressed, break from the loop
    if key == ord(q):
        break
