How to control my Drone with OpenCV?

@robolink_arnold About the delay , this is my code. Today I try the code, it happened. Maybe 1/10 , the delay above 2000ms.
from time import sleep
from petrone.drone import *
from petrone.protocol import *
from petrone.system import *
import cv2

def eventUpdateInformation(data):
print("eventUpdateInformation() / {0} / {1} / {2} / Ver:{3} / 20{4:02}.{5}.{6}".format(data.modeUpdate,
data.deviceType,
data.imageType, data.version,
data.year, data.month,
data.day))

cap = cv2.VideoCapture('rtsp://192.168.100.1/cam1/mpeg4')
#cap = cv2.VideoCapture(0)
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('outputVideo.avi',fourcc, 20.0, (640,480))

drone = Drone(True, True, True, True, True)

drone.connect()
sleep(1)

drone.sendTakeOff()
sleep(1)

while (cap.isOpened()):

ret, frame = cap.read()

out.write(frame)

cv2.imshow('frame', frame)

key = cv2.waitKey(1) & 0xFF

if key == ord("W"):
    drone.sendControl(0, 0, 0, 70)
    print("T 60")

if key == ord("S"):
    drone.sendControl(0, 0, 0, -70)
    print("T -60")

if key == ord("A"):
    drone.sendControl(0, 0, 50, 0)
    print("Y 100")

if key == ord("D"):
    drone.sendControl(0, 0, -50, 0)
    print("Y -100")

if key == ord("i"):
    drone.sendControl(0, 50, 0, 0)
    print("P 100")

if key == ord("k"):
    drone.sendControl(0, -50, 0, 0)
    print("P -100")

if key == ord("j"):
    drone.sendControl(-50, 0, 0, 0)
    print("R 100")

if key == ord("l"):
    drone.sendControl(50, 0, 0, 0)
    print("R -100")

if key == ord("z"):
    drone.sendControl(0,0,0,0)
    print("hover")
sleep(0.05)

if key == ord("q"):
    drone.sendLanding()
    print("LANDING")
    cap.release()
    cv2.destroyAllWindows()
    sleep(2)
    drone.close()
    print("CLOSE")
    break

if key == ord("x"):
    drone.sendStop()
    print("STOP")
    cap.release()
    cv2.destroyAllWindows()
    sleep(2)
    drone.close()
    print("CLOSE")
    break

print("Disconnecting device.")
drone.sendLinkDisconnect()
sleep(0.2)
drone.close()

cap.release()
out.release()

cv2.destroyAllWindows()

You may need to change the size at which you are saving the video at. First find out what the size of the output video is.

@smilebean You should not be getting a delay of 2000ms. I know however if you send a bunch of commands one after another the CoDrone will keep a buffer of all the commands therefore doing things you told it before. When using the keys you should not hold them down but instead tap them.

@robolink_arnold
Thank you! If I have any questions about openCV , i will ask for help.
