I am starting my plan for adding a video down-link to my quad copter and I have a question regarding the video input to the laptop. From everything I have seen so far it looks like most people use some type of USB video capture card for importing the live video into the mission planner. Is there any way to use an IP video source? I have access to an Axis video to Ethernet converter and would like to bring in the video that way. So my questions are:

1. Is it possible to use an IP based video source?

2. Are there any USB capture boards that are known to work out of the box?

Thank you

Keith

currently it is not possible.

What camera do you have? and what format does it output?

Sorry for highjacking but probably good idea to keep similar questions together.

I have a similar problem here, ie how to get real-time hud display up and working?

Config page only shows webcam option (ignores my working video grabber)?

Michael, what is in the video input requirement/format?

I want to usb in, no firewire on my W7 laptop

any usb directshow capture device will work.

Ip transmit video if you can do.

I am using this system. integration with the apm planner is what is missing.

The Analog Camera Wireless Digital Video System connects to any analog camera and converts the signal to digital, which is then broadcast over the 802.11n wireless protocol. This means you to can use analog cameras as IP cameras and connect to them using the  Base Station Digital Receiver. Converting analog cameras to digital with the Analog Camera Wireless Digital Video System allows you to:

  • Connect to an any NTSC or PAL analog camera over the 802.11n protocol
  • Stream live video over the internet using wifi hotspots or any 3G device that supports tethering
  • Encrypt your video transmission to prevent unauthorized access
  • Receive static free digital images, even at the limit of the transmission range

Note that the Analog Camera Wireless Digital Video System does not support taking still pictures while recording video (for which the complete IP camera system is required).

Digital transmission has several advantages over conventional analog signals, including:

  • Image and video integrity doesn’t change as the distance between the transmitter and receiver increases. The frame rate will decrease near maximum range, but the quality of each frame will remain constant.
  • Video can be streamed over the internet. This means that you can show others exactly what the helicopter is seeing from virtually any location using either a wifi hotspot or a 3G enabled cellular device.
  • Static, white snow and other visual interference is eliminated when using a digital transmission.

  • Analog to Digital Video Converter and Server

    The Analog Camera Wireless Digital Video System features an Analog to Digital Video Converter and Server, which is mounted on the Draganflyer helicopter fuselage with any  analog camera. The Analog to Digital Video Converter and Server reads NTSC or PAL output from the analog camera and converts it to a digital signal, which is then sent to the included 802.11n Wireless Access Point. The server draws power from the helicopter flight batteries, so no external power supply is needed. It can be used to convert any of our analog cameras to digital.

    Access Point

    The access point is a device that connects to the Video Server on the helicopter and broadcasts digital video over the 802.11n wireless protocol. The wireless access point is mounted to the helicopter with the camera and allows you to connect to the camera using the  software and any laptop with an 802.11n wireless network card. You can enable wireless encryption to keep the video stream secure.

    Analog Camera and Mount (optional if upgrading existing Draganflyer Camera)

    The Analog Camera Wireless Digital Video System is compatible with all Analog Cameras and mounts. Add an optional analog camera and mount if you want to add digital functionality to an analog camera you don’t already own.

    Base Station Digital Receiver

    The Base Station Digital Receiver is an 802.11n wireless client that allows you to connect to and receive video transmitted from the Access Point on your  helicopter. The Base Station Digital Receiver is a Wi-Fi radio system like the Wireless Access Point, but has been configured to work as a Wireless Client. The Base Station Digital Receiver plugs into any computer running  via a standard Ethernet link, and forms a small local network between itself, your computer, and the Wireless Access Point.

    The Analog Camera Wireless Digital Video System can be either be purchased with a UAV helicopter and analog video camera, or it can upgrade an existing analog camera to use Digital signals.


I use software http://www.videolan.org/vlc/  for playback of video.

in the next version i will be adding mjpeg support.

ie if it plays in vlc it should work in the planner.

Norman,

 

what sorta distance do you get outa that setup. I have been thinking about doing the same as you listed.

Right now I don't have any cameras picked out. I have access to a few Sony bullet cameras but I have not decided yet. My plan was to use an analog video transmitter to get the video to the ground, convert it to an IP based video, and then try to display it in the mission planner. We have done this on several other UAV projects I have worked on at work and was hoping it was possible here as well. I will take a look at the mission planner code and see if it can be added easily.

a new planner has just been uploaded to the download section.
just right click the hud, and put in the mjpeg url

a project to make 30 km with 15 km repeater excellent image
program was to link remote tv.


The problem is for us lesser mortals who can't immediately lay their hands on $3,265.95 USD less shipping just for getting a hud to work, there is a real problem with windows, even more acute with W7, that it appears wholly inadequate to process analogue video to digital with capture via usb (new laptops are coming with no firewire, pcmcia slots, s-video or composite rca etc)

I've managed to get real time on screen display, it's delayed, jerky and just chronic. although the recorded video itself when played back is ok, and smooth. Next problem is to get this into the GS planner. There is very little support around, just google for w7 video capture problems, the internet is full of questions with no answers...

With the capture device up and running, the display is good and flowing real-time, it only goes into the jerky mode when recording. Its not the laptop either, I'm running i7 sandy bridge with max ram installed, w7 64bit.

Suppose I could try using the display in non recording mode just for the hud display, and then run a separate program capturing the laptop screen for later playback. Although the problem remains of getting the planner to work with the usb capture device...

For instance windows movie maker works, Ulead photo studio works, sony vegas don't, it only accepts firewire in. Has anyone else got a hud up and running? I would like to know how you managed it. I'm already in pretty deep here money-wise.

well ive used a standard $20 tv capture usb device on windows 7 from deal extreme without any issue, connected to an imersion rc analog video system, and works find with the planner.

also if you use the above as a guide, i think you could do it alot cheaper. the Ubiquity radio gear is just wifi network gear, and is cheapish. then its either by a ip camera, or use the analog to digital converter.
