CAMERA 10X ZOOM, STABILIZED BY APM 2.5

After a year of having purchased the camera FH 10 with 10x zoom, the first experiences were poor due to the lack of a system of stabilization.

then decided dusting the camera again and stabilize with AMP 2.5. using the PAN and TIL my RVJET, to install it sideways. in my skywalker 1900. the camera has stabilization in the ROLL axis, the flight height is 300 meters and the loiter radius is 200 meters.

Good start. There has been a revolution in brushless direct drive gimbals lately that will do a MUCH better job then servos when it comes to stabilizing the camera.

I did some similar tests a while back (zoom camera) and the news helicopter type of footage is very well suited for video stabilization after the fact. If you want to have a look I have included a program SmoothFlight that I wrote to test this. Just unzip the smoothflight.zip and copy your video inside the folder. Then run "smoothflight.exe videofilename.mp4" to execute. Press the 1 and 2 key to switch between view modes.

thanks john for the file, I will try to use it. as you say have now been developed many gimbals, but nearly all are designed to be used in Multicopters. There is a need for a low cost gimbal for use in aircraft. this would be very interesting artwork.

John.

I'm trying to run, but fails to work for me. works with any video format? any size of video?

It uses FFmpeg for video decoding so any of the usual formats like mp4, mkv etc should work. I downloaded you video from youtube (mp4) and it played just fine.

John,

My network is blocking the link to your program. Possible to get it in any other way?


Thanks,
Saad

John, nice work. I'm looking for a real time video stabilization software but had no luck. I do like Vreveal that does a pretty good job in real time stabilization but the version that accepts live video is over US$20K and thats the problem, every "real time" video stabilization oftware costs a fortune. Does anyone knows a cheap or free real time live stabilization software? 

I'm asking for a imint vidhancer trial to take a look, I want to test their real time mosaicing software that I think is great for UAVs. Does anyone knows a real time mosaicing software?

ALK,

Just curious, you're looking for a realtime video stabilizer for use on the UAV or on the ground station?

Regarsd,

Saad

 John Arne Birkeland,

Thanks for the SmoothFlight.exe download!

Is there any way I could see the source of your SmoothFlight app so I can port a Linux version of it?

No problem, I've added the src. But considering this is a fast and dirty test project just for myself, with little or no comments I will be very surprised if you manage to make sense of it and get it up and running. Libraries used are OpenCV, SFML and TBB (Intel Threading Building Blocks) for parallelism.

Thanks John. I am going to switch this to work with a webcam/live feed as well. This is a great head start!
