    Few seconds latency with cv2.videocapture

    Hi Hacky, Yes, I knew that the frame was cumulated, especially in the beginning when the streamon command was initiated. I tried to do this with cv2.videocapture but no luck... But, I use avPY with 'frame flushing', and it is working great. When I applied the same method to cv2.videocapture, I...

    Few seconds latency with cv2.videocapture

    Hello, Knowing that it is an old topic and was discussed a long time ago. But, I did a few hours of searching but with no luck finding the right discussion. I am trying not to use djitellopy but to capture the video stream by using the cv2.videocapture command. However, there is latency for...

    Project Share - Drone Swarm with video stream and simple formation

    Hello, I just created a Python project to control three Tello EDU with video stream and simple formation. You can see all the detailed explanations and sharing from our website - http://bversion.com/WordPress/?p=1265 Our Website - http://molex.bversion.com Our Facebook page -...

    I am new to the Tello Programming, just created a face detection & tracking program

    Yes, that's what I am going to do, thanks for your additional hints. I believe that I need to spend some amount of time to identify a good PID setup. Thanks, YOLO

    May be with the recent update, I can do two Tello EDU video streaming, going to post it to my website.

    Got it, thanks... it will be interesting if I can create a tool and change Kp, Ki & Kd in real-time and capture necessary data to review... but, I want to try the swarm control first. XD

    Um... fine tuning a full PID is not easy.. I need to further understand the whole equation and relationship, try to develp some tools to help. But, yes, I found P-only controller is working fine. May I check with you how do you fine tune the PID? purely try and error?

    Yes, I know. I just tried each movement one by one to see the result. It will be affecting each other when moving the same time.

    If I control the height only, the result is acceptable.. but when I put it together with rotation (yaw), it affects each other..

    Hi Hacky and volate!lo, Thank you very much for your time and valuable input. It gave me a heads-up that my original code was a simple P controller... I keep sticking to how to add PID to my if/then loop. Finally, I found that just replace the whole code with the PID like below, FROM...

    Hi volate!lo, Thank you very much for your detailed reply, I need time to digest and study this. Let me come back to you guys if I can achieve this... or further roadblocks. Great to join TelloPilots, big thanks to you and Hacky. Regards, YOLO

    I am new to the Tello Programming, just created a face detection & tracking program

    Thanks for your information... but I still have no clue how to properly implement PID into my program. But, I changed the speed from constant value to variable to the distance to the center, and it looks much better, can target the exact center instead of a +/- 50 box. I really want to see how...

    Hi Hacky, I spent a whole day reading and studying the PID. But, I just wonder why and how I implement PID. Is that good enough if we just vary the drone speed based on the distance away from the center? really need PID? It looks to me like it's a kind of feedback control. Thanks, YOLO
