Hi, I am a new user in Opencv. I wrote a simple code that is:

// emmb.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <Kinect.h>
#include <iostream>
#include <opencv2\core.hpp>
#include <opencv2\video.hpp>
#include <opencv2\highgui.hpp>
typedef unsigned short unit16;
using namespace cv;
using namespace std;
template <class T> void SafeRelease(T **ppT)
{
    if (*ppT)
    {
        (*ppT)->Release();
        *ppT = NULL;
    }
};


int _tmain(int argc, _TCHAR* argv[])
{
    IKinectSensor* pSensor;
    HRESULT hResult = S_OK;
    hResult = GetDefaultKinectSensor(&pSensor);
    if (FAILED(hResult)){
        std::cout << "Error : GetDefaultKinectSensor" << std::endl;
        return -1;
    }
    hResult = pSensor->Open();
    if (FAILED(hResult)){
        std::cout << "Error : IKinectSensor::Open()" << std::endl;
        return -1;
    }
    IDepthFrameSource* pSource;
    hResult = pSensor->get_DepthFrameSource(&pSource);
    if (FAILED(hResult)){
        std::cout << "Error : IKinectSensor::get_FrameSource()" << std::endl;
        return -1;
    }
    IDepthFrameReader* pDepthReader;
    hResult = pSource->OpenReader(&pDepthReader);
    if (SUCCEEDED(hResult)){
        std::cout << "Error : IFrameSource::OpenReader()" << std::endl;
        return -1;
    }
    int l = 0;
    int Width = 512;   // ...... 1
    int Height = 424;
    cv::Mat BufferMat(Height, Width, CV_16UC1);   // ...... 3
    cv::Mat DepthMat(Height, Width, CV_8UC1);   // ...... 3
    cv::namedWindow("ebi");

    while (l<1){
        // Frame

        IDepthFrame* pDepthFrame = nullptr;
        hResult = pDepthReader->AcquireLatestFrame(&pDepthFrame);
        if (SUCCEEDED(hResult)){
            unsigned int bufferSize = 512 * 424 * sizeof(unsigned short);
            unsigned short* pBuffer = nullptr;
            hResult = pDepthFrame->AccessUnderlyingBuffer(&bufferSize, reinterpret_cast<UINT16**>(&BufferMat.data));
            if (SUCCEEDED(hResult)){
                /* Processing*/
                BufferMat.convertTo(DepthMat, CV_8U, -255.0f / 8000.0f, 255.0f);  
            }

        }


        SafeRelease(&pDepthFrame);
        cv::imshow("Depth", DepthMat);
        cv::waitKey(0);
        if (cv::waitKey(30) == VK_ESCAPE){
            break;
        }



        l++;
    }
    cin.get();
    return 0;

}

But the output in debugging is:

The thread 0x9bc has exited with code -1 (0xffffffff).

look at your code, it's probably one of those:

   if (FAILED(hResult)){
        std::cout << "Error : GetDefaultKinectSensor" << std::endl;
        return -1;
    }

(try to give them a disinctive return vale, so you can see, which one ecatly was triggered)

(also, maybe try to run your exe from cmdline (not from ide), so you can see, what got printed to stdout, you missed the message, because the window was closed immediately after the error)

I changed it:

 if (SUCCEEDED(hResult)){
            /* Processing*/
            BufferMat.convertTo(DepthMat, CV_8U, -255.0f / 8000.0f, 255.0f);  
        }

But a new message is:

First-chance exception at 0x55F07648 (opencv_highgui2413d.dll) in emmb.exe: 0xC0000005: Access violation reading location 0x00000068.
