ubuntu12.04 安装 opencv 2.4.8（非源代码编译）

一：安装所须要的各种库，如GTK3.xx

安装GCC：sudo apt-get install build-essential

安装CMakesudo apt-get install cmake

sudo apt-get install python3.2-dev python-numpy libgtk-3-dev ffmpeg libavcodec-dev

libavformat-dev libswscale-dev libjpeg-dev libpng12-0 libpng12-dev libpng++-dev libpng3

libtiff4-dev libjasper-dev libgstreamer0.10-0-dbg libgstreamer0.10-0 libgstreamer0.10-dev

zlib1g-dbg zlib1g zlib1g-dev libbz2-dev  libxine1-ffmpeg  libxine-dev libxine1-bin

libdc1394-22-dev libdc1394-22 libdc1394-utils

libv4l-0 libv4l-dev

或者不放心的话。安全点，把以下的所有安装了，一劳永逸

apt-get install build-essential
     apt-get install cmake
       apt-get install pkg-config
       apt-get install libpng12-0 libpng12-dev libpng++-dev libpng3
       apt-get install libpnglite-dev libpngwriter0-dev libpngwriter0c2
       apt-get install zlib1g-dbg zlib1g zlib1g-dev
       apt-get install libjasper-dev libjasper-runtime libjasper1
       apt-get install pngtools libtiff4-dev libtiff4 libtiffxx0c2 libtiff-tools
       apt-get install libjpeg8 libjpeg8-dev libjpeg8-dbg libjpeg-prog
       apt-get install ffmpeg libavcodec-dev libavcodec52 libavformat52 libavformat-dev
       apt-get install libgstreamer0.10-0-dbg libgstreamer0.10-0  libgstreamer0.10-dev
       apt-get install libxine1-ffmpeg  libxine-dev libxine1-bin
       apt-get install libunicap2 libunicap2-dev
       apt-get install libdc1394-22-dev libdc1394-22 libdc1394-utils
       apt-get install swig
       apt-get install libv4l-0 libv4l-dev
       apt-get install python-numpy
       apt-get install libpython2.6 python-dev python2.6-dev 

假设运行上面的方法，安装opencv的时候遇到错误，再装以下的包吧：

安装Git（可选）

sudo apt-get install git

安装GTK开发版

sudo apt-get install libgtk-3-dev

安装pkg-config

sudo apt-get install pkg-config

安装Python

sudo apt-get install python3.2-dev

安装Numpy

sudo apt-get install python-numpy

安装媒体包：

sudo apt-get install ffmpeg

安装可选媒体包：

sudo apt-get install libavcodec-dev libavformat-devlibswscale-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev

二：从opencv官网下载源代码包，编译。安装

• 编译

进入opencv2.4.5所在文件夹，新建build文件夹

1 $ cd ~/opencv.2.4.8  # the directory should contain CMakeLists.txt, INSTALL etc.
2 $ mkdir  build       # create the output directory
3 $ cd build
4 $ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON .. 

这时makefile已经生成了，能够看到显示默认安装文件夹是/usr/local。 之后运行

1 $ make
2 $ sudo make install

make的运行过程大概须要半个小时的时间

 

编译完之后，在/etc/ld.so.conf 文件中加上一行/usr/local/lib, 执行命令 

1 $ sudo ldconfig

 

编译完成

• 測试

  1 $ cd ~/opencv2.4.8/samples/c
  2 $. bash build_all.sh
  3 $ ./delaunay

測试：

编译例程

cd ~/OpenCV-2.4.8/samples/c

chmod +x build_all.sh

bash ./build_all.sh



运行程序，假设正常的话应该在lena的脸上画一个蓝色的圈

./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascade_frontalface_alt.xml" --scale=1.5 lena.jpg

或者

1 $ cd ~/opencv2.4.5/samples/c
2 $ g++ `pkg-config --cflags opencv` -o cvtest cvtest.c `pkg-config --libs opencv`

5 ########注意：g++ 后边那个东西是 ` ，就是ESC下边那个键##########
6 ###########################################################

在运行上述測试方法时，可能会遇到各种报错，这时能够试着运行下述命令

1 #安装libcv-dev，libcvaux-dev，libhighgui-dev包
2 $ apt-get install libcv-dev libcvaux-dev libhighgui-dev
