因为需要用到contrib模块的ximgproc，但是发现平时使用的opencv中没有，问了ai才知道这是contrib模块中的，需要重新编译，过程略微烦人，这里给其他人做个参考

1. opencv4.10下载以及contrib下载

opencv下载地址：所有版本地址

opencv4.10.0下载，下面三个默认随意一个就行，我下载的是windows，会下载一个压缩包

放到自己选定的位置后解压，会得到下面的东西

opencv_contrib下载地址：https://github.com/opencv/opencv_contrib，进入以后先确认是不是4.x版本，然后下载压缩包

解压缩以后如下：

2. CMake下载

我们需要Cmake软件来编译，下载链接：https://cmake.org/download/
我下载的是4.2.1版本，选择Binary distributions的Windows x64 ZIP，下载完成后解压

然后在bin目录下找到camke-gui.exe文件，双击打开

3.编译

我先把原来opencv4.10.0的所有内容都放在了新创建的source文件夹中，然后创建build，contrib两个文件夹，build为空，一会用来存放编译的文件，contrib文件夹里面放置的是刚才下载的contrib压缩包里面的东西

build为空文件夹

contrib里面内容如下，其实就是把前面下载的contrib压缩包内容复制过来

source文件夹内容如下，其实就是前面下载的opencv4.10.0的内容

接下来打开cmake，选择源路径和输出路径，然后点击configure按钮，注意此处我已经编译好了，为了演示我重新创建了文件夹，要是前面有路径什么完全跟我一样的请注意此处文件夹变了，你们不用变，按照你们的来

点击configure以后会弹出下面的窗口，需要你选择使用的VS版本和平台

我选择的如下：

然后点击finish开始配置，配置完成后大概率看到满江红，红色的全是异常

然后在Serach中搜索：OPENCV_EXTRA_MODULES_PATH        搜索的时候一定要注意有没有空格，只要有空格你就找不到了。将路径值改为你的contrib里面的modules路径；注意，必须点一下下面的modules文件夹图标，点完以后会帮你把"\"换成“/”,机器无法识别"\"；

然后继续搜索：搜索的时候一定要注意有没有空格，只要有空格你就找不到了
OPENCV_ENABLE_NONFREE          选中（专利算法模块，SIFT和SURF等）

下面这个也建议勾选上，能生成一个整合的dll，不然你就得一个个添加到引用了

弄完以后再点一次configure按钮，这是第二次点了

然后发现上面还是红的，但是之前是全红，现在有一半都白了

现在还有很多红的原因是缺少很多文件，报错内容大概是这些，基本都是文件缺失

为了方便可以在这个大佬的博客地址https://blog.csdn.net/gitblog_06749/article/details/147173043下载.cache的压缩包来替换出问题的地方

下载以后解压会看到下面的内容，然后解压缩.cache.7z

解压后得到：

把这些东西全部复制到前面opencv4.10.0里面的source/.cache文件夹下，全部替换，然后查看.cache的ffmpeg、ippicv、xfeatures2d/boostdesc、xfeatures2d/vgg文件夹里面的文件大小是不是0kb，如果不是0kb就说明对了，是0kb那就有问题，再来一遍吧

全部替换完成后，再次点击CMake的configure按钮，这是第三次点击了，不出意外的话上面就应该没有红色的了

到这基本就完成了，然后点击Generate按钮生成VS项目，生成以后进入build文件夹，找到OpenCV.sln，打开它

4. 生成

打开以后显示如下，首先将debug改成release，然后右键ALL BUILD项目点击生成,有需要可以把debug也生成一遍，反正我两个都生成了

然后就可以去干别的了，这个过程比较久，大概十分钟

然后就有两个结果，一个是生成成功，皆大欢喜，另一个是一堆报错，这个时候肯定是前面camke出问题了，问ai找方法吧，我就是折腾了两天

这样就是生成成功了

最后一步生成INSTALL项目，这一步会将编译好的库文件、头文件复制到你 CMake 中CMAKE_INSTALL_PREFIX指定的目录（比如F:/opencv-4.10.0/build/install），是后续使用 OpenCV 的关键。

这个生成的就快了，嗖嗖的，生成后在build目录下就能看到install文件夹，里面内容如下，现在可以把这个install文件夹复制到你的项目中使用

如果前面你没有勾选生成BUILD_opencv_world的话，你的lib目录下就会有一堆dll

如果勾选的话最后就只有一个，直接引用就行

以上就全部完成了，仅供参考
