需要的安装包

• GCC 4.4.x or later
• CMake 2.6 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

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

安装包下载链接  http://opencv.org/downloads.html

用CMake搭建OpenCV环境

1. Create a temporary directory, which we denote as <cmake_binary_dir>, where you want to put the generated Makefiles, project files as well the object files and output binaries.

2. Enter the <cmake_binary_dir> and type

   cmake [<some optional parameters>] <path to the OpenCV source directory>
   

   For example

   cd ~/opencv
   mkdir release
   cd release
   cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
   

3. Enter the created temporary directory (<cmake_binary_dir>) and proceed with:

   sudo make
   sudo make install
   
   默认安装路径为“usr/local”，执行成功后，头文件将会被安装到 “usr/local/include” 目录中，库文件安装在 “usr/local/lib” 目录中，帮助文件安装在 “usr/local/share” 目录中。

配置openCV参数设置

1.在/etc/ld.so.conf.d/opencv.conf文件中加入一行：/usr/local/lib ,
可能会没有opencv.conf这个文件，那我们就自己创建一个:

sudo gedit/etc/ld.so.conf.d/opencv.conf

然后再执行上一步操作，即添加

/usr/local/lib 

2.使用下面这条命令：

sudo ldconfig

3.在 /etc/ bash.bashrc（sudo gedit/etc /bash.bashrc以root进入才能修改）中加入：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

测试

找到安装包下samples文件，cd到cpp文件，里面有很多.cpp文件，例如drawing.cpp,facedetect.cpp，我的路径是/home/xxxx/opencv-3.0.0/samples/cpp

编译drawing.cpp生成可执行文件drawing

g++ drawing.cpp -o drawing `pkg-config opencv --cflags --libs`

执行可执行文件drawing

./drawing

结果如下:

同样方法得到可执行文件facedetect，并执行(1.jpg是和可执行文件facedetect放在同一个文件夹下的)

./facedetect 1.jpg

结果如下：

如有问题联系loxaywx@126.com，欢迎相互交流。
