Close range tracking (torso), angle of body

DusX

I think I will need to do some kinect tests. Not sure I can get a reliable skeleton that close, even with the Kinect 2.

I haven't tried it on 90 edge.. I will report back on this.

Are there any USB webcams that are good for IR work? I can use IR LEDs to light the background.. and workout a silhouette... maybe send out to some openCV script to get orientation.

I don't know any cameras that are good for IR. Sorry.

I am thinking a modded ps3 eye.
Anyone have experience with this?

I bought a snap on wide angle lens for my kinect. Increases the angle quite a bit!

Have you tried using the built in Eyes or Eyess++ actors when using a difference actor?

I was able to very quickly set up a video in watcher->difference=>eyes and have it easily track my shifting back and forth between standing straight and leaning to the sides. . . With smoothers and some fussing it may do what you need.

@Aolis
Eyes is my go to.

I need the lighting/contrast to be fool-safe, since this project will be traveling without me.

I am going to get a PS eye, and mod it.. it seems easy and low cost..

As I test it, I will post my results.

@gapworks

I haven't seen these. Do you have a link to one you could share?

Dear @DusX,

Could you use fiducial markers? For instance, if you had the fiducial pattern on the costume, but done it such a way that the fabric does _not_ reflect IR, and the fiducial marker _does_ reflect IR, then you could make it so that the marker was invisible (at least somewhat?) to the naked eye. The benefit to this approach is that fiducial markers give you not only position, but rotation as well.

Here's a software that uses fiducial markers.

Just a thought.

Best Wishes,

Mark

@mark, this would be a great approach if I had control over the user, but this is meant to be open to the public to interact with.

I am happy if I can get some basic swaying of the users body.

That would suit the interactive element nicely...

so I'm going to test Kinect and the PS eye.

Wish me luck.

@DusX -- GOOD LUCK! ;-)

If it is just torso angle a gyro and wireless arduino would be easier imho. No tracking just real data.

Aolis

Good luck!!! Would love to know if you figure something out that can be as robust as you need. -A

@DusX

after the Werkstatt i tried to mod our ps eye but failed as there are different versions on the market, if you buy one just be aware of this difference.

You can take the easy way out (for searching modified PS3 eye IR camera)

@Fred

Thanks... I had looked at this site some time back but didn't have the link anymore.

@m_theater

Helpful piece of information for sure... thanks.
