一、下载源码
安装软件版本为：opencv-3.2.0.zip
软件包： 链接：pan.baidu.com/s/1d51XYqoU… 提取码：c8vv
二、安装相关库与工具
1.安装相关库
sudo apt-get update # 更新软件源
sudo apt-get install build-essential # 安装编译所需的库
sudo apt-get install libgtk2.0-dev libavcodec-dev libavformat-dev libswscale-dev python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libtiff4.dev libswscale-dev libjasper-dev libdc1394-22-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev pkg-config
2.安装cmake
sudo apt-get install cmake
三、编译
1.unzip opencv-3.2.0.zip 解压 2.进入解压后的目录，创建build目录（该目录的名称可以随意设置，创建目录的目的是为了编译不污染源码） 3.进入build目录 执行
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
执行这步后出现的信息

等待ippicv_linux_20151201.tgz下载完毕，出现如下信息即可make编译。

4.make -j 8
（参数说明 -j 8 作用是充分利用CPU进行编译，提高编译速度。物理机CPU核心数多少就设置多少，8表示开8线程进行编译，我是8核因此设置8，其次如果在虚拟机上操作，参数设置应该小于CPU核心数，不然物理机太卡编译反而慢。）

编译成功
5.make install
四、测试
1.添加库路径 sudo vi /etc/ld.so.conf.d/opencv.conf
输入如下内容，保存退出。
/usr/local/lib
2.添加环境变量
sudo vi /etc/profile
末尾添加
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
3.更新环境变量
source /etc/profile
运行简单的demo，效果如下说明安装成功。
