Is OpenNI2 support multiple Kinect v2 on one computer?

I am trying to build a multiple Kinect large-scale application. Hope you guys could reply me.

Hi,

As far as I'm aware (or at least at the time I wrote OpenNI2 Kinect 2
driver), official MS Kinect v2 SDK doesn't support multiple sensors
connected to the same system. Thus, OpenNI2 doesn't support it either as it
works on top of the MS driver.

I've seen some recent work on writing a reversed engineered driver for
Linux, although I didn't take a thorough look at that. If you feel strong
enough, you can check whether it supports multiple sensors and write an
OpenNI2 driver for Linux :-) I'm sure the OpenNI community will really
appreciate it.

Thanks,
Miguel.

Thank you Miguel! I will go and check!

Hi,

First , I used Kinect v2 on Linux through OpenNI2, but I don't know whether multiple Kinect v2s work well. I have only 1 Kinect v2.
As far as I know, there is a Kinect v2 driver for Linux (https://github.com/OpenKinect/libfreenect2) , and I have written an OpenNI2 driver (#46). But libfreenect2 is still unstable and its interface may change. So my driver may not work with current libfreenect2.(Actually I have finished our previous project and I don't use Kinect v2 now.) Someone tried using my driver but it was not so easy. (OpenKinect/libfreenect2#168)

Thanks,
Masaki

Awesome! I didn't have the time to look at that myself, but it's good to
know there is some work done on that front.

I'll try to get some time and look at your work.

Thanks!
Miguel.

Hi,

I think some guys has already implemented 2 Kinect v2 on one linux computer by using libfreenect2, I am trying to do the same thing on Windows platform...

I'm trying to interface kinect for windows v2 sensor with openni2 via ros by following the following. It turns out that when I launch

roslaunch openni2_launch openni2.launch

I get errors of the following similitude:

Does anybody have an experience with this?

Are you seeing those messages every single time you launch the application?
Or it eventually works?

Thanks,

Miguel.

Every single time I launch the application, brother!

EDIT: IT hasn't worked.

@lakehanne have you tried our kinect2 branch?
