我试图在运行Ubuntu 14.04.2的计算机上安装带有额外模块的OpenCV（我需要这个特定版本的Ubuntu，因为我正在使用其他需要它的硬件）。我上周刚刚在Raspberry Pi 3上运行它（运行Ubuntu Mate 16.04.3），但现在我似乎无法做到这一点。
我知道opencv_contrib-version需要与opencv-version相同，我尝试过很多不同的版本（3.4.0,3.3.0,3.2.0,3.1.0） ）。
下载了opencv和opencv_contrib的匹配版本后，我从终端执行以下命令：
$ cd opencv
$ mkdir build
$ cd build
$ cmake -D OPENCV_EXTRA_MODULES_PATH = ../../opencv_contrib/modules ..
其中opencv和opencv_contrib文件夹都位于桌面上，因此＆＃34; ../../ opencv_contrib / modules＆＃34; -path应该是正确的。
但是额外的模块还没有建成。以下是cmake输出的部分内容：
- OpenCV模块：
- 即将建成：core flann imgproc ml objdetect photo video dnn imgcodecs shape videoio highgui superres ts features2d calib3d拼接视频标签
- 已禁用：世界
- 依赖性禁用： -
- 不可用：cudaarithm cudabgsegm cudacodec cudafeatures2d cudafilters cudaimgproc cudalegacy cudaobjdetect cudaoptflow cudastereo cudawarping cudev java python2 python3 viz
正如您所看到的，它只是包含的标准模块。我见过很多人遇到同样的问题，但解决方案一直是关于拥有匹配的opencv / opencv_contrib版本。现在我知道版本是正确的，我不知道我做错了什么。

调用中=周围有多余的空格，因此路径设置不正确。删除这两个空格你应该没问题：
