Status: offline 		If you've got some extra cash, pick up some virtual reality goggles and link them to the video out. You need to be seated (so you don't fall down when you spin!) and have someone on a buddy box (so you don't crash!) if you try this.

We have a color system w/ 1.3 mile range. We also record the flights during dogfights hoping for a camera-center mid-air. We've only gotten the debris on film so far.

Even on a rainy day you can still be in the cockpit by watching the tape with the VR goggles. We are working on a telemetry system so we could fly by TV monitor - our main problem is finding an instrument small enough to indicate altitude. Any ideas?

Status: offline 		Hello Gubnuh...

Congratulations! You are doing what I have thought about for a long time. Do the goggles you have give a 3D effect? That is does each eye see a stereoptic image. To do this I assume a person would need two cameras and two down-links.


For me the first step would be to obtain the goggles that could accept two video images. Can you suggest a couple of brands?

Thanks
Bill

I have one, and just get the board only and it goes inline with your video signal. You can also connect a GPS super easy. Just plug it in!

Status: offline 		VR or virtual reality is different from this thread's current example of projected small displays (such as iGlasses, etc). iGlasses are a simple, accessible, inexpensive, and great way to view the on-board camera image. They cost just a few hundred dollars. iGlasses are fed a single video signal from the on-board camera (on-board transmitter to the on-ground receiver) and GPS data can be overlayed (as seen on the link in the post above).

Flying with iGlasses (or any type of HUD/video lcd) can be tricky... primarily because the camera's field of view is narrow (~50mm) and it's difficult for the pilot to get a grasp of the entire geography (especially during take-off and landing). High-flying is not too difficult with iGlasses, but a spotter is highly recommended.

Loosing field orientation can be easy when wearing the iGlasses and flying high (above 500 feet).. again because of camera field of view. We've found a half-baked remedy:

1. Pipe the on-board GPS data into a laptop (the CPU is on-ground).
2. Using Syzygy or another real-time visualization application, render very basic terrain data and orientation (not just altitude and speed, but more importantly, terrain markers).
3. Overlay this simple render over the on-board video so the pilot can view the camera image as well as real-time geospatial data on the iGlasses.

Note: Even simple terrain data overlays can complicate flying. Typically simple markers such as a wireframe flag noting where the field is (and a moving vector if the field isn't in view....so the pilot can quickly navigate back) is all that's required. Any extraneous or complicated viz overlay disrupts points of interest and more importantly, pilot orientation.

This works very nicely.

Status: offline 		I flew my 30 sized heli via a 3d VR interface 2 years ago. I set up a dual set of ccd cameras, transmiters and receivers ... I wired 2 paist os Sony Glasstron HUD visors together for separate left and right view to each eye.

I managed to align the cameras fairly well and was getting true 3d depth perception. It was fun flying the heli from the HUD, but I could only go under 500 feet away with my setup ... Also, 5 minutes of this would give me a nasty headache (going crosseyed) it was neat to fly nose in and actually be looking at myself ...

the whole project 2 years ago cost me over $2000, and im sure this stuff is still up there $$
