在ubuntu 16.04上安装opencv和opencv_contrib

在ubuntu 16.04上安装opencv 3.3.1和opencv_contrib 3.3.1

0. 

$sudoapt-getupdate
$sudoapt-getupgrade
1.安装官方给的opencv依赖包

GCC 4.4.x or later
CMake 2.6 or higher
Git
GTK+2.x or higher, including headers (libgtk2.0-dev) # 控制opencv GUI
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

$ sudo apt-getinstallbuild-essential

$ sudo apt-getinstall cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

$ sudo apt-getinstall python-dev python-numpy libtbb2 libtbb-dev libjpeg8-dev libpng12-dev libtiff5-dev libjasper-dev libdc1394-22-dev # 处理图像所需的包

$ sudo apt-getinstall libavcodec-dev libavformat-dev libswscale-dev libv4l-dev liblapacke-dev

$ sudo apt-getinstall libxvidcore-dev libx264-dev # 处理视频所需的包

$ sudo apt-getinstall libatlas-base-dev gfortran # 优化opencv功能

$ sudo apt-getinstall ffmpeg

$sudoapt-getinstalllibgtk-3-dev

$sudoapt-getinstalllibatlas-base-devgfortran

$sudoapt-getinstallpython2.7-devpython3.5-dev

2.
Download the opencv source

这里需要下载opencv和opencv_contrib（后者会在cmake配置的时候用到），这是因为opencv3以后SIFT和SURF之类的属性被移到了contrib中。

$ wget https://github.com/opencv/opencv/archive/3.3.1.zip # 从github上直接下载或者clone也可

$ wget https://github.com/opencv/opencv_contrib/archive/3.3.1.zip[/code] 3.配置编译opencv（无NVIDIA
CUDA版本）

将上述opencv包解压，然后cmake配置属性

$ cd opencv-3.3.1

$ mkdir build$ cd build

$ cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D INSTALL_C_EXAMPLES=OFF \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.3.1/modules \
-D PYTHON_EXCUTABLE=/usr/local/bin/python \
-D WITH_TBB=OFF \
-D WITH_V4L=OFF \
-D WITH_QT=OFF \ # 1
-D WITH_GTK=OFF \
-D WITH_OPENGL=OFF \
-D BUILD_EXAMPLES=ON ..

$ make -j4

$ sudo make install

$ sudo /bin/bash -c'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'

$ sudo ldconfig

4.完成安装并测试

$ls-l/usr/local/lib/python2.7/site-packages/

total 1972
-rw-r--r-- 1 root staff 2016608 Sep 15 09:11 cv2.so

$python

>>>importcv2
>>>cv2.__version__
