本文記錄了ubuntu下使用源碼手動安裝opencv的過程。步驟來自opencv官網html

此外記錄了在python中安裝及載入opencv的方法。python

一、安裝opencv所需的庫（編譯器、必須庫、可選庫）

轉載請說明http://www.cnblogs.com/llxrl/p/4471831.htmllinux

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

1 [compiler] sudo apt-get install build-essential
2 [required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
3 [optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

二、從官網下載最新opencv源碼（2.4以上）

http://sourceforge.net/projects/opencvlibrary/git

或者githubgithub

三、編譯opencv

將opencv放至任意目錄，解壓ubuntu

unzip opencv-3.0.0-rc1.zip測試

建立編譯目錄，編譯ui

cd ~/opencv-3.0.0-rc1
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install

四、測試opencv

1) 建立工做目錄

mkdir ~/opencv-lena
cd ~/opencv-lena
gedit DisplayImage.cpp

2) 編輯以下代碼

#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;
}

3) 建立CMake編譯文件

gedit CMakeLists.txt

寫入以下內容spa

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

4) 編譯

cd ~/opencv-lena
cmake .
make

5) 執行

此時opencv-lena文件夾中已經產生了可執行文件DisplayImage，下載lena.jpg放在opencv-lena下，運行.net

./DisplayImage lena.jpg

6) 結果

五、安裝python-opencv

可直接使用apt安裝

sudo apt-get install python-opencv
sudo apt-get install python-numpy

測試:

打開python，import cv模塊成功便可。

import cv
