OpenCV 窗口无法加载

Question

我正在做指纹匹配的项目，我是 openCV 库的新手，

这是一个显示直方图的简单代码，存在于openCV的示例文件夹中

int main(int, char** argv)
{
    Mat src, dst;

    /// Load image


    src = cv::imread("‪contour.jpg");
    cv::waitKey(5000);
    //waitKey(0);
    if (!src.data)
    {

        return -1;
    }

    /// Separate the image in 3 places ( B, G and R )
    ..
    vector<Mat> bgr_planes;
    split(src, bgr_planes);

    /// Establish the number of bins
    int histSize = 256;

    /// Set the ranges ( for B,G,R) )
    float range[] = { 0, 256 };
    const float* histRange = { range };

    bool uniform = true; bool accumulate = false;

    Mat b_hist, g_hist, r_hist;

    /// Compute the histograms:
    calcHist(&bgr_planes[0], 1, 0, Mat(), b_hist, 1, &histSize, &histRange, uniform, accumulate);
    calcHist(&bgr_planes[1], 1, 0, Mat(), g_hist, 1, &histSize, &histRange, uniform, accumulate);
    calcHist(&bgr_planes[2], 1, 0, Mat(), r_hist, 1, &histSize, &histRange, uniform, accumulate);

    // Draw the histograms for B, G and R
    int hist_w = 512; int hist_h = 400;
    int bin_w = cvRound((double)hist_w / histSize);

    Mat histImage(hist_h, hist_w, CV_8UC3, Scalar(0, 0, 0));

/// Normalize the result to [ 0, histImage.rows ]
    normalize(b_hist, b_hist, 0, histImage.rows, NORM_MINMAX, -1, Mat());
    normalize(g_hist, g_hist, 0, histImage.rows, NORM_MINMAX, -1, Mat());
    normalize(r_hist, r_hist, 0, histImage.rows, NORM_MINMAX, -1, Mat());

    /// Draw for each channel
    for (int i = 1; i < histSize; i++)
    {
        line(histImage, Point(bin_w*(i - 1), hist_h - cvRound(b_hist.at<float>(i - 1))),
            Point(bin_w*(i), hist_h - cvRound(b_hist.at<float>(i))),
        Scalar(255, 0, 0), 2, 8, 0);
        line(histImage, Point(bin_w*(i - 1), hist_h - cvRound(g_hist.at<float>(i - 1))),
            Point(bin_w*(i), hist_h - cvRound(g_hist.at<float>(i))),
        Scalar(0, 255, 0), 2, 8, 0);
        line(histImage, Point(bin_w*(i - 1), hist_h - cvRound(r_hist.at<float>(i - 1))),
            Point(bin_w*(i), hist_h - cvRound(r_hist.at<float>(i))),
            Scalar(0, 0, 255), 2, 8, 0);
    }

    /// Display
    namedWindow("calcHist Demo", WINDOW_AUTOSIZE);

    imshow("calcHist Demo", histImage);

    waitKey(0);

    return 0;

    }

我将文件 contour.jpg 保存在与 cpp 文件相同的文件夹中。

我尝试了很多，但它显示以下警告并且不显示输出窗口。

我也尝试更改命令参数变量，仍然没有输出。

感谢您的帮助，谢谢

编辑:好的，这是我自己的问题的解决方案:

1) 我不知道自己做了什么，但我开始了一个新项目。

2) 右键单击​​您的项目，然后单击 -> 属性。

3) 取决于您的 opencv 目录(我建议 Windows 使用“C:\opencv”)

在include目录和library目录中做如下改动(选择相应的

文件夹)。我建议使用 x86 文件夹，即使你有 64 位架构。

4) 然后是以下三张图片:

最后:

在该文本空白区域添加以下文件。

注意:根据你的 opencv 版本文件名会改变，我的是 2.4.9 所以它以 249 结尾，对于那些使用 2.4.3 的人来说是 243 。

opencv_calib3d249d.lib    
opencv_contrib249d.lib    
opencv_core249d.lib    
opencv_features2d249d.lib    
opencv_flann249d.lib    
opencv_gpu249d.lib    
opencv_highgui249d.lib    
opencv_imgproc249d.lib    
opencv_legacy249d.lib    
opencv_ml249d.lib    
opencv_nonfree249d.lib    
opencv_objdetect249d.lib    
opencv_photo249d.lib    
opencv_stitching249d.lib    
opencv_ts249d.lib    
opencv_video249d.lib    
opencv_videostab249d.lib    

我希望这会有所帮助。虽然令人沮丧，但努力工作会有返回。

感谢其他成员回答我的问题。

Answer 1

处理文件(在我看来)是一件比较难做的事情。也就是说，将它们放在哪里。

尝试将图像放在与可执行文件 相同的目录中，而不是源文件中。
