1、下载对应的Opencv的版本，在官网上，下载地址：http://opencv.org/releases.html

2、安装所需要的包

GCC 4.4.x or later
CMake 2.8.7 or higher
Git
GTK+2.x or higher, including headers (libgtk2.0-dev)
pkg-config
Python 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy)
ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev
[optional] libtbb2 libtbb-dev
[optional] libdc1394 2.x
[optional] libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev, libdc1394-22-dev
[optional] CUDA Toolkit 6.5 or higher

The packages can be installed using a terminal and the following commands or by using Synaptic Manager:

[compiler] sudo apt-get install build-essential
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
3、安装所需要的包     1.首先进入解压后的opencv3.2.0的文件下，我的path在/home/yuan/opencv 3.2.0下，在该path下新建一个build文件夹存在后面安装的内容，然后在进入到build下，代码如下：
         cd /home/yuan/opencv 3.2.0
         mkdir build
         cd build
     2.进行配置。（两种配置方法，如下所示）
        cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
        or 使用cmake-gui
set full path to OpenCV source code, e.g. /home/user/opencv
set full path to <cmake_build_dir>, e.g. /home/user/opencv/build
set optional parameters
run: “Configure”
run: “Generate”
     3.Build.
        make -j7 #run 7 jobs in parallel
    sudo make install    通过上述的步骤，则完成了openv3.2.0在Ubuntu16.04上的安装
