which is essentially Kinect +Android + Google Cardboard

and a bit of duct tape.

Actually this is not a Kinect device.

I am using the ASUS Xtion Pro Live

which has an infrared pattern projector,

a color camera,

an infrared camera,

and two microphones.

So it's pretty much the same as the original Kinect for Xbox 360

except a bit smaller,

without the tilt motor,

and with a regular USB plug.

The head mount is not the real Google Cardboard either.

This is a version which is made of thick foam.

the focal length is about 60 mm,

the lenses are a bit larger,

I think they are made of glass instead of plastic,

and you can slide them here to adjust the distance.

Finally, the Android device is an old Samsung Galaxy S3

from (almost) 3 years ago.

And if we connect everything with a USB OTG cable

As you can see it just works almost out of the box.

Which is quite surprising, because this camera is really intended for desktop PCs

and I thought I would need to add an external power supply

and maybe this splitter cable

and then maybe even patch the kernel to disable the USB power management checks.

Now that we have point clouds we can render them in various ways

like false color

but of course what we really want to try is stereo.

This is side-by-side stereo.

And since we have actual 3D geometry,

we can render everything from an arbitrary point of view.

For example, here,

I am moving the camera 1 m behind and above the actual sensor.
