Question

这是我的代码，它有什么问题？

itc = contours.erase（itc）发出此错误。我在调试模式下运行它。我使用open cv 2.4.10和visual studio 2013。和调用堆栈是：

msvcp120d.dll！5bd8dfdd（）未知 [下面的框架可能不正确和/或缺失，没有为msvcp120d.dll加载符号]

ConsoleApplication3.exe！main（int argc，char * * argv）第84行C ++

#include "stdafx.h"
#include "highgui.h"
#include "opencv2\opencv.hpp"
#include "opencv2\imgproc\imgproc.hpp"




using namespace cv;
using namespace std;


bool verifySizes(RotatedRect mr){

float error = 0.4;
//Spain car plate size: 52x11 aspect 4,7272
float aspect = 4.7272;
//Set a min and max area. All other patchs are discarded
int min = 15 * aspect * 15; // minimum area
int max = 125 * aspect * 125; // maximum area
//Get only patchs that match to a respect ratio.
float rmin = aspect - aspect*error;
float rmax = aspect + aspect*error;


int area = mr.size.height * mr.size.width;
float r = (float)mr.size.width / (float)mr.size.height;
if (r < 1)
    r = (float)mr.size.height / (float)mr.size.width;

if ((area < min || area > max) || (r < rmin || r > rmax)){
    return false;
}
else{
    return true;
}

}




 int main(int argc, char** argv)

morphologyEx(img_sobel, img_sobel, CV_MOP_CLOSE, element);

vector< vector< Point> > contours;
findContours(img_sobel,
    contours, // a vector of contours

vector<vector<Point>>::iterator itc = contours.begin();
vector<RotatedRect> rects;

while (itc != contours.end()) {
    //Create bounding rect of object
    RotatedRect mr = minAreaRect(Mat(*itc));
    if (!verifySizes(mr)){
        itc = contours.erase(itc);
    }
    else{
        ++itc;
        rects.push_back(mr);
    }
}



cv::waitKey();
}

调试断言失败，带有contours.erase
