c++ - 带有 Visual Studio 2013(C++) 的 OpenCV : findContours breakpoint error

Question

我使用的是 OpenCV 2.4.10 版。

调试时出现断点错误:未加载 wkernelbase.pdb。

此外，我在 Visual Studio 的输出中得到了这个错误:

First-chance exception at 0x7543C42D in Perspective.exe: Microsoft C++ exception: cv::Exception at memory location 0x003FEDDC.
Unhandled exception at 0x7543C42D in Perspective.exe: Microsoft C++ exception: cv::Exception at memory location 0x003FEDDC.

在我的应用程序中，命令行打印出来:

OpenCV Error: Assertion failed <0 <= contourIdx< <int>last> in cv::drawContours, file...\..\..\..\opencv\imgproc\src\contours.cpp, line 1810

关于如何处理这个问题有什么建议吗？这是我的代码:

#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include "iostream"

using namespace cv;
using namespace std;
int main()
{
    Mat image;
    image = imread("shape.jpg", 1);
    namedWindow("Display window", CV_WINDOW_AUTOSIZE);
    imshow("Display window", image);
    Mat gray;
    cvtColor(image, gray, CV_BGR2GRAY);
    Canny(gray, gray, 100, 200, 3);

    /// Find contours   
    vector<vector<Point> > contours;
    vector<Vec4i> hierarchy;
    RNG rng(12345);
    findContours(gray, contours, hierarchy, CV_RETR_TREE, CV_CHAIN_APPROX_SIMPLE, Point(0, 0));
    /// Draw contours
    Mat drawing = Mat::zeros(gray.size(), CV_8UC3);
    for (int i = 0; i < contours.size(); i++)
    {
        Scalar color = Scalar(rng.uniform(0, 255), rng.uniform(0, 255), rng.uniform(0, 255));
        drawContours(drawing, contours, i, color, 2, 8, hierarchy, 0, Point());
    }

    imshow("Result window", drawing);
    waitKey(0);
    return 0;
}

我知道我的图片也在正确的目录中。

Answer 1

这是vs2013和opencv之间已知的兼容性问题

尝试替换

vector<vector<Point> > contours;

与

vector<cv::Mat> coutours;

这对我来说很有效。
