Ubuntu 系统下 OpenCV 3.1.0 编译安装

Ubuntu 系统下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>\n");

        return -1;

    }

    Mat image;

    image = imread( argv[1], 1 );

    if ( !image.data )

    {

        printf("No image data \n");

        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 linuxidc.jpg #随便一张图片都行
