@robolink_arnold Okay.Thank you!

I want to Control CoDrone do "follow me " by OpenCV , It is possible?
I find some example about tracking, they use the ccd . Is CoDrone has ccd?

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

@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()

I install drivers you say. About the delay, maybe it happened when I use pycharm and anaconda in the same time. I want to know how to do about this. I mean control the Drone with OpenCV. Is it Opencv image recognition?
About this code,I can't save the video I catch with CoDrone, but computer camera can.

The FPV transfer to PC have delay 3000~4000ms. Is it normal?
I can use the Key_Control example thank you!
Can you show me how to use OpenCV to control CoDrone?

When I use pycharm, I have the same problem(Key_Control).
And the FPV transfer to PC have delay 3000~4000ms. Is it normal?

When I create a project , how not to use the virtual env of python?
We date on monday 11pm in Taiwan.

What do I need to prepare before video call? I trying to use pycharm now .If I have any question , I will ask, thank you!
