Thanks. I am doing a bit of quad redesign but should get another movie up before to long.

Thanks for the tip Phil. I didn't know you could do that to cross the views and such. I even tried the anaglyph method with my glasses!

Now all we need are airframes built just for this so we don't have to hang all the FPV stuff on the outside, making our planes look like they came out of the garage! How about fiber optics built internal to the wings with the CCD back in the fuselage & the lenses made to look like landing lights or something?

Yeah all the fpv stuff does make them look DIY which had it's own charm of course. Video transmition is the tricky bit. Especially for stereo.

Do you use two transmitters or do you get a single video image sent

The 3D FPV CAM mixes the left right views in to a single, field sequential signal for transmition with a single transmitter.

3d fpv

Hi, I too have been trying to figure out how to put this together and am just about to pull the trigger on 3D FPV. I've had my first FPV experiences in planes and am now building my 1st Quad and also a Y6. My main motivation is that I can take it along to trips, vacations, etc. and also capture nice arial views as well as enjoy and seek out the areas I am at in the comfort of my chair.
Being a private pilot but that hobby being pretty expensive these days plus the committments of a father FPV fits in really well. That is why I am also looking into 3D FPV (for the experience) and especially on low altitude flying where 3D works and it appears that the Multicopters with their hovering abilities will be ideal. I too have done different things in 3D in the past 20 years now and technology is giving additional options now.

Couple of things I have been considering that I want to share. Perhaps also a good way to collaboratively come to a good solution and share it with the FPV community which apparently is growing pretty fast. It appears everyone around me is interested in what I am doing and starting to buy stuff. Which on one hand scares me to think of all the aircrafts up in the sky and crashing on people... because even me understanding a lot about technology have had really uncomfortable close calls because especially on FPV you can so easily go too far too fast and get yourself and others into trouble.

1. I've asked myself if going with a good 700 line camera (although it cannot be transmitted in that quality, but I have noticed a really good picture quality through what I believe is due to a better lense and resolution).
Combining it with one of those real-time 3D from 2D converters (like: http://www.3d-bee.com)... and wondered if I can achieve:
- better image quality/resolution
- one camera (simpler and cheaper setup)
- good 3d effect

2. Googles, there aren't a lot of things out there but I sense they are coming now with virtual reality and 3D in the consumer market (being an IT guy I have been following and interested in this too as well as a decent understanding in technology)
- I just noticed that Sony came out now with their goggles. Its a bit pricey but perhaps compatible for even the "field sequential 3D" and the 3D-Bee like scenario, future high resolution, use in other scenarios. I haven't dug into the specs of it yet but planned too.
These goggles are "Sony Personal 3D Viewer" Sound, HD Resolution, really large virtual screen (750" at 65 feet away (so it must have a realistic non-window effect and everything built in. $799 at the present time.

Any thoughts, any experiences with other than using the 3D nghobbies and goggles you are using?
I am using the hobbyking silver IO glasses right now (Boscam) and I have to say they are pretty good in their field of view. I wonder if those glasses you use are also giving a realistic effect and so you don't feel like you're lookint at a small TV from a distance? Do you have a comparison between this to share?

Well the good news Ocp is the 3D FPV Cam is back in stock....

http://www.nghobbies.com/cart/index....roducts_id=393

...it is the easiest way to start 3D FPV if you have field sequential compatible 3D goggles. Like any FPV camera you probably do not want to use it for capture. Other cameras like the GoPro do that much better.

I am completely with you on the 3D FPV as an 'experience'.

1. 2D - 3D converters are horrible. You have probably seen a 3D converted hollywood movie by now. Even with hundreds of artists working on them, these do not look great compare to true stereoscopic capture. Real time conversion is revolting. Go take a look and you will see. The depth ques are often completely wrong. No No No.

2. I have tried the Sony goggles in the store and they are fantastic (full HD) but they expect to be plugged into a blu-ray or game console etc so they only accept HDMI 1.4 stereo. That would be very difficult to generate from a transmitted analogue signal that we use in FPV.

The best quality you could get right now is to have two cameras and two transmitting systems going to googles with independent inputs for left and right but these goggles don't exist. You have to build your own system like VRflyer (on page 1 of this thread)
http://pilotage.immersion.free.fr/Funjet3D.html
Google translate...
http://translate.google.com/translat...FFunjet3D.html

I might try that at some point but for now the ease of use for the 3D FPV cam makes it worth the money. It acts like one camera so one transmitter etc on the quad. You just need the goggles to understand field sequential.

Unfortunately these goggles seem to be getting in short supply as it is an older stereo format. Many new 3D capable goggles only understand a side by side 3D video.

Thanks Phil. It appears that the link you sent me on the goggles are the ones you are using or similar model? ITG-HQ3D
They support field sequential. Do you know if in comparison to the Boscam or fat stark have similar quality? And if the view is clear and picture appears large and not like your looking at a big TV that is far away? I have the googles from Boscam to compare it too that I got from hobby king.

It sounds like you can lock in exposure so ground is not black when sunset, which sounds nice. That is bugging me right now.

Sounds like your happy with the result of the 3d setup you have. I've noticed that those are back in stock now too. Wanted to make sure getting these and new glasses were worth it.
I had wondered if it was hard to take 2 cams and try to get electronics to do side-by-side and send over transmitter. Probably more complex again.

I meant to add to the above:

- what the camera view angle is on the 3D? Camera set. I am using a wide angle now which is easier to fly than what first came with my FPV camera where I had no wide angle at all. I think it's about 2.5mm

- when using OSD for FPV, is this not usable for 3D? I like to record OSD info as a precaution to seeing GPS coordinates if I loose a plane. It's saved my plane last time.

I'm trying to sort out if 3D is a special application for maybe short 1 mile max lower flight situations or also for long range where having GPS data, battery levels (video and main) is useful. I currently use Eagle Tree.

Thanks, Oliver

As our choice is limited there is no need to try and compare with goggles that can not do 3D. Sorry I have not looked at Fat shark any way. Analogue video transmitted for FPV is not exactly high quality.

I just go with what is possible and right now the easiest way to see 3D FPV video is with the 3D FPV cam and a pair of the HQ3D or EVP920 goggles. Both of which seem to be end of line out of stock models. So if you are thinking about it I would recommend you jump in now if money is not an issue.

I searched for the last two days for goggles that are compatible with field sequential video. I only found the HQ3D to still be available. One site turned out to be a scam website (one.camover.co.uk). So without any choice you can do 3D FPV right now with this camera for $330 + shipping

http://www.nghobbies.com/cart/index....roducts_id=393

and these goggles for $340 + shipping

http://itvgoggles.com/details.asp?productID=2
http://www.melpiercecamera.com/prodd...d=811937010044

Pretty much $700!
Still I fully recommend it for low and slow flying with a quad especially.

If anyone finds field sequential compatible 3D goggles (not side by side 3D) then post here.

phil

PS. Headplay work as well. Range video has some stock as cheap as $199
http://www.rangevideo.com/index.php?...roducts_id=268

they also show up here in classifieds. For sale now $180
http://www.rcgroups.com/forums/showt...light=headplay

Headplay is very good.

Oh didnt really answer your questions Oilver

Yes the FPV cam has an exposure lock mode that I have hooked up to a gear switch on my Radio. I either leave it in auto mode or more typically lock it when things look good.

The camera view is wide angle but not crazy wide like a GoPro. I think it is perfect. You can see it in this video...

3D CAM FPV - Transmitted Video (1 min 54 sec)


OSD: Yes I now use an OSD and it works fine with 3D.

Or you could buy mine if you read this thread for $299 with 3D camera?

I never used the camera because of the price and I still crash.
I never felt safe enough to fly 3D. I now only risk my 45 and 16 dollar hobbyking cameras.
