调试断言失败vc \include\vector向量迭代器+偏移超出范围在chamferMatching Opencv [英] debug assertion failed vc\include\vector vector iterator + offset out of range in chamferMatching Opencv

问题描述

在OpenCV中实施倒角匹配程序时遇到问题

https：// code.ros.org/trac/opencv/browser/trunk/opencv /samples/cpp/chamfer.cpp?rev=4194

以下是正在读取的代码
template image

和测试图片

，我使用VS 2008和OpenCV2.4.6

  #includestdafx.h
 
 #include< opencv2 / imgproc / imgproc.hpp> 
 #include< opencv2 / highgui / highgui.hpp> 
 #include< opencv2 / contrib / contrib.hpp> 
 #include< iostream> 
 using namespace cv; 
 using namespace std; 
 
 int main（int argc，char ** argv）
 {
 IplImage * src; 
 src = cvLoadImage（C：\\Users\\JOSHI\\Desktop\\Images\\logo_in_clutter.png，1）; 
 Mat img = cvarrToMat（src）; 
 imshow（Mat，img）; 
 
 src = cvLoadImage（C：\\Users\\JOSHI\\Desktop\\\\\ logo.png，1）; 
 Mat tpl = cvarrToMat（src）; 
 imshow（Mat，tpl）; 
 Mat cimg; 
 
 //如果图像和模板不是边缘地图，而是正常的灰度图像，
 //您可能想要取消注释以下行以生成地图。你也可以
 //运行Sobel而不是Canny。 
 Canny（img，img，5，50，3）; 
 Canny（tpl，tpl，5，50，3）; 
 vector< vector< Point> >结果; 
 vector< float>成本; 
 int best = chamerMatching（img，tpl，results，costs）; 
 if（best< 0）
 {
 cout<< not found; \\\
; 
 return 0; 
} 
 size_t i，n = results [best] .size（）; 
 for（i = 0; i  {
 Point pt = results [best] [i]; 
 if（pt.inside（Rect（0,0，cimg.cols，cimg.rows）））
 cimg.at< Vec3b>（pt）= Vec3b（0,255,0） 
} 
 imshow（result，cimg）; 
 
 waitKey（）; 
 return 0; 
} 
  

这是错误图像

你能建议我为什么我得到这个错误，因为我是新的OpenCV和图像处理

解决方案

我有同样的问题。解决方案： http://code.opencv.org/issues/3603
您需要从源下载opencv，打开chamfermatching.cpp和注释行：

 〜Matching（）
 {
 for（size_t i = 0; i< templates.size（）; i ++）{
 // delete templates [i]; 
} 
} 
  

然后你需要重建opencv。之后它应该工作。

I am stuck with the problem while implementing chamfer matching program in OpenCV

https:// code.ros.org/trac/opencv/browser/trunk/opencv/samples/cpp/chamfer.cpp?rev=4194

Following is the code it is reading template image

and test image

, I am using VS 2008 and OpenCV2.4.6

#include "stdafx.h"

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/contrib/contrib.hpp>
#include <iostream>
using namespace cv;
using namespace std;

int main( int argc, char** argv )
{    
    IplImage *src;
    src = cvLoadImage("C:\\Users\\JOSHI\\Desktop\\Images\\logo_in_clutter.png",1);      
    Mat img=cvarrToMat(src);  
    imshow("Mat",img); 

    src = cvLoadImage("C:\\Users\\JOSHI\\Desktop\\Images\\logo.png",1);  
    Mat tpl=cvarrToMat(src);  
    imshow("Mat",tpl); 
    Mat cimg;

    // if the image and the template are not edge maps but normal grayscale images,
    // you might want to uncomment the lines below to produce the maps. You can also
    // run Sobel instead of Canny.    
     Canny(img, img, 5, 50, 3);
     Canny(tpl, tpl, 5, 50, 3);    
    vector<vector<Point> > results;
    vector<float> costs;
    int best = chamerMatching( img, tpl, results, costs );
    if( best < 0 )
    {
        cout << "not found;\n";
        return 0;
    }    
    size_t i, n = results[best].size();
    for( i = 0; i < n; i++ )
    {
        Point pt = results[best][i];
        if( pt.inside(Rect(0, 0, cimg.cols, cimg.rows)) )
           cimg.at<Vec3b>(pt) = Vec3b(0, 255, 0);
    }
    imshow("result", cimg);

    waitKey();
    return 0;
}

this is the error image

can you suggest me why I am getting this error as I am new to OpenCV and Image Processing

解决方案

I had same problem. Solution: http://code.opencv.org/issues/3603 You need to download opencv from source, open the chamfermatching.cpp and comment line:

~Matching()
{
    for (size_t i = 0; i<templates.size(); i++) {
        //delete templates[i];
    }
}

Then you need to rebuild opencv. After this it should work.
