Hello ,

Could you share your Python code and the modified TelloPy library ?

 

[Mikusan]

Holy #@!#, this is what i have been waiting for. Now if someone would make it into an app i would even pay for it nice work man!

[vtvt]

Thanks! I will continue to develop all cool things about obj tracking and I will release app in case of high demand

 

[doug01n]

That's an app I would pay for too.
I'm sending to all my Tello owner's friends.
Congratulations!!!

 

[Alastordmg]

Amazing! Looking forward to your app.

 

[Pennello]

Vtvt, please go on with your great job!!!
An App with object tracking (follow me mode) will be fantastic!

 

[Garymac]

It would be great if the tello can object track keep up with the good work

 

[MolecularConcept]

Awesome ! I like where this is going

 

[Manicearkold]

I'd pay for this app!

 

[Avellas]

I’d pay for the app as well!

Cool. You have my support for the development of an official app!

Wow wow wow, you should cooperate with the aTello guy. This Need to implement in it
I would Pay to get an App with it.

Could you share the code or Github?
Please

Yeah I am working on app, will update ASAP

Dear vtvt,

I found there is a significant delay in frame obtained using TelloPy. I even tuned down the bit rate but no help
1) For 3M, I receive ~750K bytes video data for two seconds
2) For 1M, I receive ~250K bytes video data for two seconds
It seems that receiving data is alright, the loading of CPU is just 3X%. I didn't see any remarkable frame skiping , say over 1 second. That means data is really received and processed.

Can you help? Thanks a lot

Use lower resolution: for many OpenCV application you need something like 512x512.
Skip frames if you have delay. Skip first 300 frames. Use WiFi extender. Set video quality slightly lower.

 drone.set_video_encoder_rate(1)

However I personally like approach with multi threading (no skip frames needed):

def recv_thread():
    global frameA
    global run_recv_thread
    global drone
    print('start recv_thread()')
    drone = tellopy.Tello()
    drone.connect()
    drone.subscribe(drone.EVENT_FLIGHT_DATA, handler)
    drone.set_video_encoder_rate(1)
    drone.set_loglevel(drone.LOG_WARN)
    container = av.open(drone.get_video_stream())
    while run_recv_thread:
        for f in container.decode(video=0):
            frameA = f
        time.sleep(0.01)

...

threading.Thread(target=recv_thread).start()
...
while run_cv_thread:
    if frameA is None:
        time.sleep(0.01)
    else:
        #do your opencv stuff with frameA
