向OpenCV添加我自己的函数 [英] Adding my own function to OpenCV

问题描述

我需要添加一个新的方法来计算连接的组件到OpenCV 2.4.4在我自己的项目中使用。我已经有来自此问题的函数代码（感谢 jason ），我浏览了补丁，我找到了代码和标题。

我做的是添加一个新的在 C：\opencv\modules\imgproc\src 中的文件 connectedcomponents.cpp 这个新函数的代码。接下来，我去了 C：\opencv\modules\imgproc\include\opencv2\imgproc ，我添加了适当的导出标题到 imgproc.hpp 。最后，我使用Visual Studio 2010在OpenCV源代码中重建了 opencv_imgproc 项目。一切正常，并生成 opencv_imgproc244.dll ， opencv_imgproc244.lib 和 opencv_imgproc244.exp 。

现在，我将这些文件（除了.exp，我不能找到它应该去哪里）复制到我现有的OpenCV目录并替换旧的文件。当我现在尝试构建我自己的项目，一切仍然构建良好，但我无法从这里访问新的方法。我包括 #include< opencv2 / imgproc / imgproc.hpp> ，从这里我可以访问文件中的所有其他方法，除了我想要的新。

事实上，一切都编译，但方法没有暴露导致我认为有一些其他文件，我应该改变，但是，由于缺乏

额外的信息：
我使用Visual Studio 2010，OpenCV 2.4.4和构建的OpenCV与CMake 2.8.10.2
我知道有一些库，如 cvBlobsLib 计算连接组件，我已经成功地在我的项目中使用这些。但是，我想要一个更快和更新的解决方案（cvBlobsLib仍然使用旧的IplImage）。

解决方案

今天早上用一双新鲜的眼睛，我立刻发现了我的错误。

\\ imgproc\include\opencv2\imgproc\imgproc.hpp ，

但我应该做的也将其添加到

C：\opencv\build\include\opencv2\imgproc\imgproc .hpp ，

，因为这是使用OpenCV的任何项目包含的文件。一切都按计划现在。

I need to add a new method that computes connected components to OpenCV 2.4.4 to use in one of my own projects. I already have the code for the function from this question (Thanks to jason), I navigated my way to the patch where I found both the code and the header.

What I did was to add a new file connectedcomponents.cpp in C:\opencv\modules\imgproc\src, in which I placed the code for this new function. Next, I went to C:\opencv\modules\imgproc\include\opencv2\imgproc and I added the appropriate export header to imgproc.hpp. Finally, I rebuilt the opencv_imgproc project in the OpenCV source code using Visual Studio 2010. Everything builds fine, and generates the opencv_imgproc244.dll, opencv_imgproc244.lib, and opencv_imgproc244.exp files for me.

Now, I copy these files (except for the .exp, where I can't find where it should go?) into my existing OpenCV directory and replace the old files. When I now try to build my own project, everything still builds fine, but I cannot access the new method from here. I include #include <opencv2/imgproc/imgproc.hpp>, and from here I can access all the other methods in the file, except for the new one that I want.

The fact that everything compiles but that the method is not exposed leads me to think there is some other file that I should have changed as well, however, due to lack of experience I do not know where or what this file could be.

Extra information: I am using Visual Studio 2010, OpenCV 2.4.4 and built OpenCV with CMake 2.8.10.2 I am aware that there are libaries such as cvBlobsLib that compute connected components, and I have successfully used these in my project. However, I want a faster and more recent solution (cvBlobsLib still uses the old IplImage).

解决方案

So after looking at the problem with a fresh pair of eyes this morning, I immediately spotted my mistake. What I originally did was to add the new function's header code in

C:\opencv\modules\imgproc\include\opencv2\imgproc\imgproc.hpp,

but what I should've done is to also add it to

C:\opencv\build\include\opencv2\imgproc\imgproc.hpp,

because this is the file that is included by any project that uses OpenCV. Everything works as planned now.
