Hi

Im working on a project where im trying to stream video/pictures in a very low quality from my APM board through to Mission Planner using GPRS/3g (Dronecell)

My big question is, would this even be possible to carry through? and if so, what frame size are we talking about and FPS?

If im using size 320 * 240 and 1 frame pr second,  ( 320 * 240 = 76800 * 8bit = 614400 * 1 FramePrSecond  ~ 614 Kb/s ??

Is this calculations correct if im using apm 2,5 board?

Would it be possible to compress the video stream with APM board?  

Would it be possible to merge the video stream togheter with telemetry data?

How much data is the telemetry occupies?

  • Hi Tommy

    Impressive..

    Im looking forward to read your blog.

    Do you comress the video with Raspberry before streaming?

    A video of your project would be nice ;)

  • The APM board should not be loaded with more task than it has already. I have an onboard WiFi 3g router. I connect to APM via TTL-UART to Wifi. I also connect my Raspberry Pi via WIFI to the same 3g router. Then i stream video via this router from the Raspberry Pi.

    You can merge the telemetry data with the video before you stream it. The telemetry does not require very much.

      Hi Tommy, why do you use a wifi network on your aircraft and not ethernet?

      • He is not using Wifi anymore.. This thread is old. We are using Ethernet communication.

  • Hi

    I'm currently streaming video via 3g and internet and it work very good. I use 352x288 at 10fps and 500kbit bitrate. I use the Raspberry Pi for this and VLC as streaming software. I send video using UDP for less latency, 300ms

    I also connect to my aircraft with Mission Planner at TCP through the same link. I'm working on a Blog post where i will present my solution.
