Generic OSD telemetry using OCR Technology for logging and antenna tracking

Hi All,
I just finish the first public release of my OSD recognition software.

- It "reads" OSD from capture device or recorded video to get informations like GPS, speed and altitude.
- It displays these informations to google map and allows export to various file formats (google earth, video subtitle).
- It streams data to serial port using NMEA sentence for custom processing like antenna tracking.


Here a video that shows howto use the software :
OFPV - Remzibi OSD recognition software. (2 min 16 sec)




Download (English) : http://www.psykokwak.com/
Download (French) : http://www.psykokwak.com/

For antenna tracking :
We can use my OSD recognition software with HappyKillmore's Ground Control Station using a virtual COM driver to connect both softwares together.
You will need a servomotor controller that works with HappyKillmore's GCS like the pololu micro maestro to control your pan/tilt antenna tracker.
Read the HappyKillmore's GCS documentation for futher information.

Happy Christmas

Please, If you have any comments, post them in comments on my website.

Happy Christmas

This absolute amazing!
Great work Psykokwak.

May this is the beginning of the way using one antenna tracker with different OSD’s.


Is there any chance to provide the recognized coordinates with Eagle Tree antenna Tracker?

Actually, the eagle tree antenna tracking already do the "telemetry recognition" from the video stream because it "speaks" eagle tree OSD Pro language which is specific to this OSD.

With oFPV software, we can use any OSD to decode telemetry directly from OSD and send them to a serial port.

Maybe some proud developpers will build modules (using arduino ?) to get these data, compute antenna tracking position and move motors according this position...

this would be great, because it do not bend us to one system.
This would give the opportunity to "mix" parts of FPV equipment regards to the availability and favourites of user.

Just my 2 cents

I'm working on an upgrade that send data using NMEA format instead my own format. You could use my app with HappyKillmore's Ground Control Station software to do antenna tracking.
I will publish the update today or tomorrow (with a howto use the two softwares)

is there a way to change the area of recognition? I am using DOSD and I have my Long. and Lat stacked in the lower corner.

Long.XXX.XXXXXX
Lat. YYY.YYYYYY

Thanks and nice work
Mark

Wow, that's an incredible coincidence but I did exactly the same thing 1 year ago, here is the thread you'll maybe find interesting info for your project :

http://www.rcgroups.com/forums/showthread.php?t=1338452

This was the first step :
OSD Decoder : extract the data from any OSD in real time - Proof of concept (5 min 48 sec)


This was the next one :
OSD Decoder 'reads' the OSD data, shows it in Google Earth, pilots Antenna Tracker and does Flight Analysis / Beta 1 (7 min 36 sec)


And this is the final status :
OSD Cockpit for FPV : 3D cockpit + HUD + 3D radar + antenna tracker + google earth (6 min 0 sec)


It integrates a lot of gadgets, and an antenna tracker as well, done simply by connecting a $20 sparkfun usb to servo adapter. The software does all of the calculation.

Congratulations for your project (and I know how hard it is ) !

Hi flipflap,
Thanks for your comment.
I've just finish an update that send telemetry over serial port using NMEA sentence. I've made some test with HappyKillmore's Ground Control Station software for antenna tracking and sounds good.
Why did you never distributed your application ?

Here a new video that shows how to use my software :

Update:
Antenna tracking with our remzibi (or other generic) osd become a reality

We can use my OSD recognition software with HappyKillmore's Ground Control Station using a virtual COM driver to connect both softwares together.
You will need a servomotor controller that works with HappyKillmore's GCS like the pololu micro maestro to control your pan/tilt antenna tracker.

Hi,
Great work! I would really like to use this but it appears the map is stuck on Paris? Will it automatically re-center once it has enough data?
Thx

Hi psykokwak! Great job, very nice project!

I'm wondering, would it work also for this osd I plan to make, here is the link to the video of the osd:
DIY OSD flight test (software v 0.14) (3 min 5 sec)


This diy osd by Dennis Frie is an opensource arduino design...if it would work with your software I would be super happy

Hi psykokwak,
I'm trying to get this to work to track my RSSI over distance.
I've just re-configured the OSD, large 60 font, the video is clean.

I think the OCR is struggling though...

Let me know if you want a piece of the file?
Thx

Hi Mich.
What's wrong with the software ?

Could you send me your video file ?

Hi all,
New version avaiable that fix some issues like negative lat/lng (N/S and E/W).

Changelog :
- Support N/S and E/W for Lat and Lng.
- Add CSV and NMEA export.
- Fix dragging and zooming on google map.
