在使用来自 opencv 的示例代码时,我遇到了以下错误。我对 QT C++ 很陌生,我不知道如何调试它。通常在Java中我会使用stacktrace并告诉我我在哪里搞砸了,但这似乎直接指向库。
OpenCV 错误:在 crossCorr,文件 c:/OpenCV/opencv /modules/imgproc 中断言失败 (corrsize.height <= img.rows + templ.rows - 1 && corrsize.width <= img.cols + templ.cols - 1) /src/templmatch.cpp,第 70 行终止在抛出 'cv::Exception'what() 实例后调用:c:/OpenCV/opencv/modules/imgproc/src/templmatch.cpp:70: 错误:(-215 ) corrsize.height <= img.rows + templ.rows - 1 && corrsize.width <= img.cols + te mpl.cols - 1 在函数 crossCorr
更新:构建的 .exe 文件运行但不是从 QtCreator 启动时。我能够启动构建的 .exe 文件。我从 QtSDK/Simulator/mingw/bin 复制了文件,令我惊讶的是应用程序运行成功。当我单击 Qt Creator 中的 Run 按钮时,它会抛出与上面相同的错误消息。
