openni/nite update

[hackma]

Can you update the openni/nite to the latest unstable version? Because the version have now the auto calibration feature, that the user must not do the psi pose. ;)

I have the latest libs from openni/nite/primesence installed. Can i disable openni/nite from nestk and use the unstable versions that i have also installed? I try it with NESTK_USE_EMBEDDED_OPENNi but it dont work. Maybe you can please tell me how i can upgrade the stuff.

Thx!

When i have set SET(NESTK_USE_EMBEDDED_OPENNI 0) than i get the following errors..

Have you an idea how can i fix that? The application starts rgb/depth image is working but user generator don't works :(

Hi Marco,

It should work if you disable the NESTK_USE_EMBEDDED_OPENNI cmake variable. If it doesn't, please open an issue with the errors you get.

Thanks, Nicolas

Hello, i has used the old nite version. I have now removed the old libs and reinstall the unstable openi/nite/sensorkinect stuff.

Now i can start my application, but it crashes when calibration is finished :( It must be a problem with access the m_ni_user_generator.GetSkeletonCap() in the calibrationCompletedCallback.

I have added in the openni_grabber following things to get autocalibration work:

void OpenniGrabber :: calibrationCompletedCallback(XnUserID nId, XnCalibrationStatus eStatus) { ntk_dbg(1) << cv::format("Calibration finished %d\n", nId); //m_ni_user_generator.GetSkeletonCap().AbortCalibration(nId);

if (eStatus == XN_CALIBRATION_STATUS_OK)
  {
        ntk_dbg(1) << cv::format("Calibration complete, start tracking user %d\n", nId);
        m_ni_user_generator.GetSkeletonCap().StartTracking(nId);
        return;
    }

    ntk_dbg(1) << cv::format("Calibration failed for user %d\n", nId);
   // m_ni_user_generator.GetSkeletonCap().AbortCalibration(nId);

    if(eStatus==XN_CALIBRATION_STATUS_MANUAL_ABORT)
                {
                    printf("Manual abort occured, stop attempting to calibrate!");
                    return;
                }

    if (m_need_pose_to_calibrate)
    {
        m_ni_user_generator.GetPoseDetectionCap().StartPoseDetection(m_calibration_pose, nId);
    }
    else
    {
        m_ni_user_generator.GetSkeletonCap().RequestCalibration(nId, TRUE);
    }

}

AND

XnCallbackHandle hCalibrationStart, hCalibrationComplete,hPoseDetected; m_ni_user_generator.GetSkeletonCap().RegisterToCalibrationStart(UserCalibration_CalibrationStart, NULL, hCalibrationStart); m_ni_user_generator.GetSkeletonCap().RegisterToCalibrationComplete(UserCalibration_CalibrationComplete, NULL, hCalibrationComplete);

    if (m_ni_user_generator.GetSkeletonCap().NeedPoseForCalibration())
    {
        m_need_pose_to_calibrate = true;
        if (!m_ni_user_generator.IsCapabilitySupported(XN_CAPABILITY_POSE_DETECTION))
            ntk_throw_exception("Pose required, but not supported\n");

        //m_ni_user_generator.GetPoseDetectionCap().RegisterToPoseCallbacks(UserPose_PoseDetected, NULL, this, hPoseCallbacks);
        m_ni_user_generator.GetPoseDetectionCap().RegisterToPoseDetected(UserPose_PoseDetected, NULL, hPoseDetected);
        m_ni_user_generator.GetSkeletonCap().GetCalibrationPose(m_calibration_pose);
    }

    //m_ni_user_generator.GetSkeletonCap().SetSkeletonProfile(XN_SKEL_PROFILE_ALL);
    m_ni_user_generator.GetSkeletonCap().SetSkeletonProfile(XN_SKEL_PROFILE_UPPER);

Nicolas have you tried out the auto calibration? Are my changes correct in the openni_grabber.cpp class? I did the same as in the Simple_UserTracker example from openni.

Thanks for your help!
