Robot master TT video stream problem (no frame) #98

Closed FachengG closed 3 years ago

FachengG commented 3 years ago

Hello! I am very new to drone and found dji just have a new product release, witch is the Robot master TT. It has an off-line program feature and I think combine this with openCV can be very interesting.

I am very new to drone and encounter a problem with the camera (take picture / video stream). I am not sure this is my script's problem or dji updated their program?

When execute following code:

import cv2
import time
from djitellopy import Tello

tello = Tello()
tello.connect()

time.sleep(1)
tello.takeoff()
tello.move_forward(100)
tello.streamon()
frame_read = tello.get_frame_read()
cv2.imwrite("picture.png", frame_read.frame)

tello.land()

Here is my log:

Could anyone help me with this problem?

Hey,

your problem sounds similar to #90. Which opencv version are you using?

Also you can try changing your code to the following, basically setting the ports and turning on streaming before takeoff:

import cv2
import time
from djitellopy import Tello

tello = Tello()
tello.connect()

tello.send_command_with_return("port 8890 11111")

tello.streamon()
frame_read = tello.get_frame_read()

time.sleep(1)

tello.takeoff()
tello.move_forward(100)
cv2.imwrite("picture.png", frame_read.frame)

tello.land()

Hey M4GNV5, thank you very much for your help!

Unfortunately, I cannot try your solution anymore. I just returned my Robot master TT, because the off-line program system is too weak. It does not worth the money.

If anyone encounter the same problem with Robot master TT, please try M4GNV5's solution! Hope it will work.
