ubuntu16.04下安装opencv-3.1.0及其扩展模块opencv_contrib

步骤1.安装依赖项

sudo apt-get install build-essential cmake git libgtk2.-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

可选的

sudo apt-get install checkinstall yasm libtiff5-dev libjpeg-dev libjasper-dev libdc1394--dev libxine2-dev libgstreamer0.-dev libgstreamer-plugins-base0.-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils libeigen3-dev

步骤＃2：下载OpenCV源代码

为了方便，我已经包含了opencv归档文件的完整URL以及下面的opencv_contrib归档文件：

• https://github.com/Itseez/opencv/archive/3.1.0.zip
• https://github.com/Itseez/opencv_contrib/archive/3.1.0.zip

步骤3.生成cmake编译配置

这里下载文件可能会出错，解决办法就是去官网下载ippicv_linux_20151201.tgz，然后放到该路径下

下载 ippicv_linux_20151201
/home/computer/opencv-3.1.0/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/  没有的文件夹要新建

创建编译目录

 cd opencv-3.1.  mkdir release  cd release

编译opencv及opencv_contrib

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/home/opencv/opencv_contrib/modules/ ..  

如果不安装opencv_contrib模块，则第二步的命令为：
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local  

CMAKE_INSTALL_PREFIX为你的opencv安装路径，OPENCV_EXTRA_MODULES_PATH是你的opencv_contrib/modules/的路径，可以参照在我的电脑上为

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local/opencv-3.1. -D OPENCV_EXTRA_MODULES_PATH=/home/zn/opencv-3.1./opencv_contrib-3.1./modules/ ..

4.安装

make
sudo make install

make的时候大概会出现报错，参考以下链接解决

https://github.com/opencv/opencv/issues/6016

5.测试

查看opencv版本

pkg-config --modversion opencv

在我的电脑上大概编译20分钟就可以完成了
