代码是我结合kinect sdk 2.0 里面的例程和其他网友的代码写出来的。  
如果你想在你的电脑上实现我的代码，那你的电脑需要满足以下两个条件：

1.  硬件设备：kinect v2；
2.  编译环境：kinect sdk 2.0 + Opencv3.0 配入编译环境

环境配置： https://blog.csdn.net/m0_38128647/article/details/76030275

代码如下：

#include <iostream>
    #include <opencv2\imgproc.hpp> 
    #include <opencv2\calib3d.hpp>
    #include <opencv2\highgui.hpp>
    #include <Kinect.h>
    
    using   namespace   std;
    using   namespace   cv;
    
    // Safe release for interfaces
    template<class Interface>
    inline void SafeRelease(Interface *& pInterfaceToRelease)
    {
    	if (pInterfaceToRelease != NULL)
    	{
    		pInterfaceToRelease->Release();
    		pInterfaceToRelease = NULL;
    	}
    }
    
    Mat ConvertMat(const UINT16* pBuffer, int nWidth, int nHeight, USHORT nMinDepth, USHORT nMaxDepth)
    {
    	cv::Mat img(nHeight, nWidth, CV_8UC3);
    	uchar* p_mat = img.data;
    	const UINT16* pBufferEnd = pBuffer + (nWidth * nHeight);
    	while (pBuffer < pBufferEnd)
    	{
    		USHORT depth = *pBuffer;
    		BYTE intensity = static_cast<BYTE>((depth >= nMinDepth)&&(depth<= nMaxDepth)?(depth%256):0);
    		*p_mat = intensity;
    		p_mat++;
    		*p_mat = intensity;
    		p_mat++;
    		*p_mat = intensity;
    		p_mat++;
    		++pBuffer;
    	}
    	return img;
    }

    		}
    		SafeRelease(pDepthFrameSource);
