Wider FOV than 58 degree lenses?

<t>Heya! <br/> <br/> I'm just wondering - would it be possible to use an even wider FOV with Optitrack and Arena than the 3.5mm M12 lenses you sell?<br/> <br/> I'm specifically talking about usage with a v100 here - I notice that it's possible to acquire 2.1mm lenses with an 80-ish degree field of v...

Re: New Flex cameras - capture volume?

I'll be interested to hear your updates, for values of "interested" meaning "might buy quite a few cameras". :)

New Flex cameras - capture volume?

<t>So, I saw a press release today which said Optitrack was releasing new "Flex" cameras. And the PR says <br/> <br/> "When deployed with the stock 56� lens in a standard 20' x 20' arrangement, the camera can attain an active capture area that is among the largest in the industry, which allows for...

Re: HUGE balls (and a much larger capture area)

<t>Ah, not very easily, I'm afraid - our mocap setup isn't terribly accessible without some notice! (Problems of being in the UK - there's a bit of a "large, accessible, cheap - pick two" issue around space here.) <br/> <br/> We put velcro on the points where the markers usually attach, and attached...

Re: HUGE balls (and a much larger capture area)

<t>25' was the square side. <br/> <br/> We set the system up as follows: <br/> <br/> 2 cameras - 16' USB cables - OptiHub - 16' USB cables - 2 cameras <br/> <br/> | <br/> <br/> 25' space<br/> <br/> |<br/> <br/> 2 cameras - 16' USB cables - OptiHub - 16' USB cables - 2 cameras <br/> <br/> However, as...

Re: HUGE balls (and a much larger capture area)

<t>OK, I've now tried this out. <br/> <br/> The system can certainly see the markers much further away - about double the range over which it can see the standard 5/8" markers. <br/> <br/> We attached larger markers to the 3-point calibration wand, moved our system to an 8-camera configuration with ...

HUGE balls (and a much larger capture area)

<t>Heya! <br/> <br/> I've been having some discussions with a friend of mine who has been working on mocap systems professionally for a decade or so, and he came up with an interesting suggestion. <br/> <br/> Is there any reason that it wouldn't be possible to significantly extend the capture volume...

Re: Training vids/ebook for using Arena - interested?

Thanks, guys - interesting to hear!

I'm considering a bunch of projects right now - I'll add it to the possibles list.

If anyone else is interested - do comment, the more demand the more likely it is to happen!

Training vids/ebook for using Arena - interested?

<t>Hey, guys! <br/> <br/> Quick question for the Forum Denizens: I'm currently putting together training videos for a variety of 3Dish topics. We've also been using Optitrack Arena for getting on for two years, and we've uncovered a lot of gotchas that I see plaguing other people on the forums. <br/...

Re: skeleton over time loses calibration

<t>I've had this problem too. We've found that a full recalibration helps temporarily - however, sometimes even if we recalibrate and create a new skeleton, I recall having increased inaccuracy problems. <br/> <br/> It's not a killer problem, and recalibration helps a lot, but I'd love to know why i...
