Creating A Usertracker Crashes In Nite2 Python Bindings

I am trying to use OpenNI2 and NITE2 python bindings. I'm under Windows 7 and I have Kinect SDK1.8, OpenNI 2.2 and NITE 2.2 working without problems in Visual C++ with their 32 bit

Solution 1:

I've finally been able to make it work but I trully think there's a mess with versions regarding Nite and primesense python bindings, so I'll share in case someone goes through the same problems.

When I posted the question I was using (as indicated) the python bindings downloaded from openNI website and Nite 2.2.

I tried downloading the latest version from pyPi, which is 2.2.0.30-5 and then I got an error when initializing nite2 (nite2.initialize()) because it wasn't able to find the method niteDumpUserTrackerCalibrationDataToFile in the C API.

The "solution"? I downgraded Nite to version 2.0, where that method is actually present. I think this is not the best solution. The latest versions for Nite and its python bindings should work together without having to hack the code or downgrading.

To summarize: it's working for me with python bindinngs 2.2.0.30-5 from pyPi and Nite 2.0.0, but is should work with Nite 2.2.

Solution 2:

Yes, niteDumpUserTrackerCalibrationDataToFile is missing from 2.2, but there also another problem in using NiTE 2.2 from Python.

NiTE 2.2 is not playing well with ONI file devices, because it says that it requires a "PrimeSense SOC" device. This can be discovered by enabling logging in NiTE.ini

Solution 3:

This fork of the openni-python bindings solves the problems mentioned in this post regarding Nite 2.2. I am aware it is in the process of being merged back to the original openni-python github project.
