Hi,

I am making a home made head tracker as I don't want to invest $300 NZD in a Track IR 5.

 

First of all, I am not sure whether my webcam I am using is up to the job. Anyone know if this model will work?

 

fbc09843-35a1-4d30-8aef-cf614960c36f_zps

(Logitech C300)

 

Also, is this the IR filter? (I can't find out online)

I also don't know whether I should remove the IR filter or not as it seems very weak. (The webcam can see IR light in normal daylight)

This is shown here.

(This setup consists of 2.4V with a 15ohm Resistor and a 50mA led, I will be getting better leds in the future. http://nz.element14....ial/dp/1212738)

 

With 3 pieces of exposed, developed film over the lens of the webcam and at the distance I would normally have the leds to the webcam, the leds aren't so bright.

 

9191ec1f-29a0-448c-ae92-aa07f77d41ed_zps

(Where I would sit when using the tracker)

 

Even though its not too bright, can it still be picked up by free track? Am I required to remove the IR filter in the webcam?

Also, Should I place more film over the lens to eliminate the background light or will this affect the tracking ability?

 

 

Any information will be much appreciated, Micah.

Sony PSEYE seems to be a camera of choice with quite a few of the Freetrack guys.

Hello Micah.

 

I can get a sony ps3 cam for $12  + a bit of IR band pass filter to you. if you like.

 

you need this:

 

https://codelaborato...cts/eye/driver/

 

I use it with FT and it's great. 75 fps.

 

You may be able to use it with the IR filter in it. ( To negate making a mess of your camera.)

 

I will test that out actually...

 

The track point setup I have been using is really good, will post a pic and diagram soon.

 

I am in Hamilton btw...  it's quite boring... : )

This is my normal rof profile. 

Made specially for turn fighting against the Dr1's...

 

I use the boring 5mm IR leds from jaycar. with the round lense filed flat.

and a cell phone charger PSU.

 

Total cost:  about $20 nzd.

 

I can't imagine TIR is any better.... 

 

Map the CENTRE button to your stick.  recentre when you slouch etc... 

and the OUTPUT on/off so you can fiddle your snap views.

Hi Planky,

 

Thanks for the help! Much appreciated!

 

I had originally bought some of those 5mm leds from jaycar, but they couldn't find them or get them to ship up to the far north (Ahipara).

That's why I bought really cheap, better leds off ebay from China. $3 NZD for 10 :)

I will mostly be using this tracking system on racing games with my new second hand g27 racing wheel but I might get into flying games. Years ago I played a little IL-2 with a useless joystick.

 

Does the IR filter need to be removed in the PS3 eye and is the IR band pass filter placed over the lens?

And when I start free track it sensors the background light from outside which mucks everything up, if I place more film negative over the lens will that stop that from happening?

 

Thanks, Micah

Thanks

Got some detailed info there and could offer help if you're interested.

 

No camera, no filter removing...

Hi,

I am currently using Free Track with my 3 Point clip model but free track ins't being supported any more by the developers so I can only play a 32bit version of Euro Truck Simulator. American Truck Simulator or any racing games I play aren't supported. My camera also only has 15 FPS max so it's extremely laggy. I read that FaceTrack works with point models. Do you have any experience with that software?

Thanks

This is my 3point tracker

Hi,
A lot of ppl use Opentrack instead of freetrack and I believe it is still being supported for newer games.

I use freetrack as it supports the wiimote as a camera.

Plank,
Do you use the feature that links z translation to increased smoothing? So when you zoom in camera, and lean towards the screen a bit, the smoothing amount is increased until you lean back. Nice while circling over camels (or n28s) at a safe height :)

Nope. I just use EDTracker and opentrack. Check the link I posted above to see more details.
