【问题描述】：

我尝试关注https://docs.opencv.org/3.1.0/d4/d18/tutorial_sfm_scene_reconstruction.html 这段代码，但它无法构建。我使用opencv和extra-contrib 3.4.5版

我尝试将 .dll 添加到项目中，但它不起作用。

还有这个 .exe 错误

【问题讨论】：

我相信解决方案是找出丢失的 dll 在哪里。

标签： c++ opencv

【解决方案1】：

这是 Windows API 框架的常见模式。您安装/构建一些框架，该框架带有一组 INCLUDE、LIB 和 DLL 文件。您的代码包含头文件和与 DLL 存根 lib 文件的链接，以便进行编译。但在运行时，无法找到依赖的 DLL，因为它们不在您的 PATH 中（或与 EXE 位于同一文件夹中）。

对话框实际上是在告诉您错误。将 ceres-debug.dll 复制到与 EXE 相同的文件夹中。或者最好，如上所述，只需确保包含 ceres-debug.dll 的任何文件夹都在您的 PATH 环境变量中。通过更新 PATH，您可能会为您的程序或 ceres-debug.dll 所依赖的附加 DLL 解决许多后续错误。

有意义吗？

此外，“DLL 搜索顺序”的快速 google 有几篇很好的文章解释了这个主题：https://docs.microsoft.com/en-us/windows/desktop/Dlls/dynamic-link-library-search-order
