Question

Im using Opencv 2.3.1 on Visual studio 2010 (vc10)
I have configured opencv based on many tutorials and can compile & run C-syntax program like:

www.un.org/Depts/DGACM/index_spanish.htm

#include "StdAfx.h"
#include <iostream>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

int main ()
{
    IplImage* img = cvLoadImage("D:cat_helmet.jpg", CV_LOAD_IMAGE_UNCHANGED);
    cvNamedWindow("display", CV_WINDOW_AUTOSIZE);
    cvShowImage("display", img );
    cvWaitKey(0);        

    return 0;
}

However, I cannot run the C++ syntax program like www.un.org/Depts/DGACM/index_spanish.htm

#include "StdAfx.h"
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std; 

int main(  )
{ 
    namedWindow( "Display window", CV_WINDOW_AUTOSIZE );
    Mat image;
    image = imread("D:cat_helmet", CV_LOAD_IMAGE_COLOR);   

    if(! image.data )                             
    {
        cout <<  "Could not open or find the image" << std::endl ;
        return -1;
    }
    imshow( "Display window", image );                   

    waitKey(0);                                          
    return 0;
}

我收到错误信息(职能电话: 姓名:,mread,imshow)。

First-chance exception at 0x5361fcc3 in FirstOpencv2.3.exe: 0xC0000005: Access violation reading location 0x2079616c.

Unhandled exception at 0x5361fcc3 in FirstOpencv2.3.exe: 0xC0000005: Access violation reading location 0x2079616c.

我如何确定这一点?

Answer 1

You say that you have followed a multitude of guides and tutorials. I ve had great success with this one http://www.anlak.com/using-opencv-2-3-1-with-visual-studio-2010-tutorial/

事情是,这gu横穿公园,帮助你在建立开放式CV 2.3.1时揭开两个主要问题,其中之一是将彩票档案放在你的项目夹中。另一件是失踪的拖车_。

他还为你尝试(在C++ syntax)提供了一些体面的编码。

Good luck.

Answer 2

上述答复没有意义。我也面临同样的问题。造成这一例外的主要原因是,你试图展示出空洞的图像(通过透镜阅读)。该方案的主要问题是:

    image = imread("D:cat_helmet", CV_LOAD_IMAGE_COLOR);

我认为,不起作用并没有达到预期效果。还有一点是,在通过参考文件时,我有以下联系:

阅读(经过精心设计、档案、挂旗)

这里,通过参考方法使用透镜。我不是C++专家,但我觉得可能是问题。

    int main() 
    {
      std::string imgPath("splash.bmp"); //Add your file name
      Mat img = imread(imgPath);
      namedWindow( "Example1", WINDOW_AUTOSIZE);
      imshow("Example1", img);
      waitKey(0);
      return 0;
    }

这部法典对我有效。此外,我把案卷放在旁以减轻复杂性。
