    Face tracking with tello and gocv

    Hello, everyone. Please check out the latest versions of Gobot and GoCV. The newest GoCV includes updated installation instructions for OpenCV 3.4.2 Also, the Tello examples have been updated, and also I've added a version of the face tracking Tello based on the cool work from Javaguy.

    Tello. Whats possible?

    Take look at this example, which I think should do exactly what you want: hybridgroup/gobot

    Tello. Whats possible?

    Looks like you need to still need to follow the "Getting Started" instructions for installing Gobot itself? Getting Started - Gobot - Golang framework for robotics, physical computing, and the Internet of Things (IoT) I'd suggest opening a Github issue to reduce noise on this Tello forum...

    Tello. Whats possible?

    Seems like perhaps the image is missing for the page "Overall Control Message Flow"?

    Great work once again, bluejune. Thanks!

    Tello. Whats possible?

    It has been a team effort, with most of the heavy lifting being done by bluejune and Krag. But thanks!

    Just published a new blog post about hacking the Tello: Hello, Tello - Hacking Drones With Go Thank you to everyone on this group who has helped make it happen!

    Tello. Whats possible?

    Not error free yet. However I see that I get better results when I set the coding rate: hybridgroup/gobot I get the feeling that there is some initial initialization needed to be sent to the drone to get a clean feed, that I am not sending yet. bluejune has an updated lua script for packets...

    Getting the sdk to recognize flip commands

    Those are lb', 'lf', 'rb' and 'rf', but I have not tried them yet. Currently charging battery...

    Getting the sdk to recognize flip commands

    Thanks, Krag. The flip values I have found so far are: 0 = front 1 = left 2 = back 3 = right One note: the sequence bytes are needed in order for the command to recognized by the drone. E.g. CC 60 00 xx 70 5c 00 e6 01 ZZ xx xx Thanks again for the info!

    Getting the sdk to recognize flip commands

    Krag, if you can capture some flip packets from the app, I can delve into the exact protocol. According to PingguSoft / pytello / source / tello2.py — Bitbucket it is cmd 92

    Tello. Whats possible?

    That makes me think your entire problem is related to Windows Firewall. You might need to check those settings.

    Tello. Whats possible?

    Hi, Krag Thanks for the comment. If I skip writing the [0x00, 0x00, 0x00, 0x01] part of the packet, the h264 video no longer plays back due to missing data/errors in the header. In order for it to play back using ffplay, it appears that data needs to be in the file to indicate that it is...

    Tello. Whats possible?

    Here is the link to my WIP Golang code to capture video from Tello: hybridgroup/gobot Once I have the saved video file, I can view it by running: ffplay /path/to/tello.h264 There are many errors while paying back the resulting file, but it does function.

    Tello. Whats possible?

    Just was able to write a video file, that I was then able to play back in ffplay, basically by requesting the PPS header info every 100 ms. That seems excessive, right? I think the timing of the various requests might be important, I am going to dig in a bit more. Also, need to figure out how...
