• ubuntu 系统 opencv3.1.0 安装


    opencv编译安装

    编译环境安装:

     sudo apt-get install build-essential
    

    必需包安装:

    sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
    

    可选包安装:

    sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
    

    opencv下载:

      稳定版

    wget https://github.com/Itseez/opencv/archive/3.1.0.zip
    

      github源代码

    git clone git://github.com/Itseez/opencv.git
    

    创建编译的临时目录:

    cd ~/opencv
    mkdir build
    cd build
    

       注意: 这里假设opencv解压开的或者从github获取的源代码目录在用户主目录下。

    生成cmake编译配置:

    cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
    

    编译:

    make -j4 # runs 4 jobs in parallel
    

    安装opencv:

    sudo make install
    

    运行测试:

    git clone https://github.com/Itseez/opencv_extra.git
    OPENCV_TEST_DATA_PATH=~/opencv_extra
    ~/opencv/build/bin/opencv_test_core
    

    一个例子:

    首先创建一个目录 test,并进入目录:

    mkdir test
    cd test
    

    其次,创建文件 DisplayImage.cpp 如下:

    #include <stdio.h>
    #include <opencv2/opencv.hpp>
    using namespace cv;
    int main(int argc, char** argv )
    {
        if ( argc != 2 )
        {
            printf("usage: DisplayImage.out <Image_Path>
    ");
            return -1;
        }
        Mat image;
        image = imread( argv[1], 1 );
        if ( !image.data )
        {
            printf("No image data 
    ");
            return -1;
        }
        namedWindow("Display Image", WINDOW_AUTOSIZE );
        imshow("Display Image", image);
        waitKey(0);
        return 0;
    }
    

     接着,创建cmake配置文件 CMakeLists.txt,如下:

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

     最后运行:

    ./DisplayImage psu.jpg #随便一张图片都行
