ubuntu14.04安装opencv3.1

1.下载opencv3.1源码http://opencv.org/releases.html

2.安装opencv3

2.1安装opencv3的依赖

sudo apt-get install build-essential libgtk2.0-dev libvtk5-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev libtbb-dev

2.2解压下载的源码并创建编译目录

 unzip opencv-3.1..zip
 cd opencv-3.1./
 mkdir build
 cd build

2.3.cmake生成make文件并安装

 cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv3.1.0 -D WITH_TBB=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
 make
 sudo make install

3.opencv3.1使用

如果之前安装了opencv2的版本，需要在～/.bashrc中添加

 export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opencv3.1.0/lib/pkgconfig
 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/opencv3.1.0/lib

通过输入，以下命令可以查看opencv版本

  pkg-config --modversion opencv

版本为3.1.0

此外需要在使用opencv的工程中对CMakeLists.txt 添加如下配置

 set( CMAKE_CXX_FLAGS "-std=c++11" )
 set(OpenCV_DIR "/usr/local/opencv3.1.0/share/OpenCV")
 find_package( OpenCV 3.1 REQUIRED )
 include_directories( ${OpenCV_INCLUDE_DIRS} "/usr/local/opencv3.1.0/include")
 target_link_libraries( imageBasics ${OpenCV_LIBS} )
