想用别人的C++程序进行kinect采集数据并记录
程序如下，红色的几句是我自己加的，但是好像无法从skeletonFrame里面输出数据？#include "stdafx.h"
#include <windows.h>
#include <iostream>
#include <NuiApi.h>
#include <opencv2/opencv.hpp>
#include<fstream>

//1、初始化NUI，注意这里是USES_SKELETON
HRESULT hr = NuiInitialize(NUI_INITIALIZE_FLAG_USES_SKELETON);
if (FAILED(hr))

cout<<"NuiInitialize failed"<<endl;

}
//2、定义骨骼信号事件句柄
HANDLE skeletonEvent = CreateEvent( NULL, TRUE, FALSE, NULL );
//3、打开骨骼跟踪事件
hr = NuiSkeletonTrackingEnable( skeletonEvent, 0 );
if( FAILED( hr ) )
{
cout<<"Could not open color image stream video"<<endl;
NuiShutdown();

}

//4、开始读取骨骼跟踪数据
while(1)
{
NUI_SKELETON_FRAME skeletonFrame = {0};//骨骼帧的定义
bool bFoundSkeleton = false;
//4.1、无限等待新的数据，等到后返回
if (WaitForSingleObject(skeletonEvent, INFINITE)==0)
{
//4.2、从刚才打开数据流的流句柄中得到该帧数据，读取到的数据地址存于skeletonFrame

} 把out<<skeletonFrame<<endl;改成了out<<&skeletonFrame<<endl; 但是还是只能显示图像，并没有生成data.txt这个文件，也没有数据{:10_266:}
