OpenCV-ubuntu-install

1.安装一些依赖库

sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev cmake libswscale-dev libjasper-dev

2.下载源码并编译

opencv的下载地址：http://opencv.org/downloads.html

unzip opencv-x-x-x.zip
cd opencv
mkdir build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make -j  && make install 

3.安装和 配置

sudo vi /etc/ld.so.d/opencv.conf
输入：
/usr/local/lib
保存并退出
运行ldconfig使生效
sudo ldconfig 
在shell的配置的文件中加入
我使用的是oh-my--zsh,所以在~/.zshrc中加入就可以了
#opencv config

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

4.测试

显示图片

ShowImage.cpp

 /**

  *            Author                  :kangkangliang
  *            File desc               :test Opencv
  *            Mail                    :942504876@qq.com

  */

 /**
  *                                             headfile
  */
 #include <iostream>
 #include <fstream>
 #include <vector>
 #include <string>
 #include <iterator>
 #include <opencv2/core/core.hpp>
 #include <opencv2/imgproc/imgproc.hpp>

 using namespace std;
 using namespace cv;
 /**
  *                                            main function
  */
 int
 main(int argc,char **argv)
 {
     ///        error way
     if (argc < )
         cout << "usage :./show image_name" << endl;

     ///        read image from agrv
     Mat        src = imread(argv[]);
     if (!src.data)
     {
         cout << "read iamge error" << endl;
         return -;
     }

     /// show image
     imshow("image",src);
     waitKey();
     return ;
 }

make.sh 脚本

 #g++ -Wall -std=c++0x $ -o $obj
 g++ -Wall -std=c++0x $  `pkg-config --cflags --libs opencv` -o  `echo $ | cut -d '.' -f1`
 #./`echo $ | cut -d '.' -f1`

$sh make.sh ShowImage.cpp
$./ShowImage image_name

或者使用cmake来编译

编写CMakeLists.txt

 cmake_minimum_required(VERSION 2.8)
 project( ShowImage )
 find_package( OpenCV REQUIRED )
 add_executable( ShowImage ShowImage.cpp )
 target_link_libraries( ShowImage ${OpenCV_LIBS} )

$cmake .

$make

$./ShowImage image_name

祝你成功，开始OpenCV之旅！！！

note：懒人的话就直接用opencv-install 脚本
