【问题描述】：

我在我的 Cli/cpp 项目中遇到了堆损坏问题。

似乎只有在未附加调试器或未使用依赖项步行工具进行分析时才会出现问题。

在我看来，应用程序在释放一些内存时首先崩溃。

如果有人可以看一下，请告诉我我是否在以下代码中做了一些非常糟糕的事情，这可能会导致这种情况。

std::string imagePath = msclr::interop::marshal_as< std::string >(Path::Combine(this->context->WorkingDirectory, this->context->Payload->ImagePath));
std::cout << imagePath << std::endl;
cv::Mat image = cv::imread(imagePath);

if (!image.data)

    throw gcnew System::Exception("image data is not loaded");



std::vector<cv::Point2f> src;
src.push_back(cv::Point2f(0, 0));
src.push_back(cv::Point2f(0, image.rows));
src.push_back(cv::Point2f(image.cols, image.rows));
src.push_back(cv::Point2f(image.cols, 0));

cv::Mat M = cv::getPerspectiveTransform(src, dst);

cv::Mat warp_img((ymax - ymin + 1)*tileSize, (xmax - xmin + 1)*tileSize, CV_8UC3);



std::vector<cv::Point2f> obj_corners(4);
obj_corners[0] = cv::Point(0, 0); obj_corners[1] = cv::Point(image.cols, 0);
obj_corners[2] = cv::Point(image.cols, image.rows); obj_corners[3] = cv::Point(0, image.rows);

std::vector<cv::Point2f> scene_corners(4);

cv::perspectiveTransform(obj_corners, scene_corners, M);

cv::warpPerspective(image, warp_img, M, cv::Size((xmax - xmin + 1)*tileSize, (ymax - ymin + 1)*tileSize));
image.release();


cv::Mat warp_img_fliped;
cv::flip(warp_img, warp_img_fliped, 0);
warp_img.release();

String^ id = Guid::NewGuid().ToString();

std::vector<int> compression_params;
if (this->context->Payload->Extension->Equals(".png"))
    compression_params.push_back(CV_IMWRITE_PNG_COMPRESSION);
    compression_params.push_back(9);


if (this->context->Payload->Extension->Equals(".jpg"))
    compression_params.push_back(CV_IMWRITE_PNG_COMPRESSION);
    compression_params.push_back(this->context->Payload->Quality);



for (int r = 0, rr = (ymax - ymin + 1)*tileSize, ty_idx = ymax; r < rr; r += tileSize, ty_idx--)
    for (int c = 0, cc = (xmax - xmin + 1)*tileSize, tx_idx = xmin; c < cc; c += tileSize, tx_idx++)
    
        std::cout << ty_idx << " " << tx_idx << std::endl;

        cv::Mat tile = warp_img_fliped(cv::Rect(c, r, tileSize, tileSize)); 

        String^ Path = Path::Combine(this->context->WorkingDirectory, id,String::Format("0\\1\\2\\3", zoom,tx_idx,ty_idx, this->context->Payload->Extension));
        Directory::CreateDirectory(Path::GetDirectoryName(Path));               
        std::string path = msclr::interop::marshal_as< std::string >(Path);
        cv::imwrite(path, tile, compression_params);
    

warp_img_fliped.release();

【问题讨论】：

次要帮助：检查未在 ctor 中初始化的类成员。 （这可能很明显）

现在没有什么是显而易见的 :)

另一点：确保您没有将调试与发布库混为一谈。我不知道为什么，但我观察到在使用 CV 时会这样做

【参考方案1】：

所以错误甚至在我上面发布的代码之前。

通过一次取一行并返回，我能够找到堆损坏的原因。

double pxpy[2] =  (double)xmin * tileSize, (double)ymin * tileSize ;  
pixelsToMeters(pxpy, zoom, initialResolution, mxmy);

上面的作品和下面是导致错误的原因

pixelsToMeters(new double[]  (double)xmin * tileSize, (double)ymin * tileSize , zoom, initialResolution, mxmy);
