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(wǎng)

此外記錄了在python中安裝及載入opencv的方法。

轉(zhuǎn)載請說明http://www.CUOXin.com/llxrl/p/4471831.html

• 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-essential2 [required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev3 [optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

或者github

將opencv放至任意目錄，解壓

unzip opencv-3.0.0-rc1.zip

創(chuàng)建編譯目錄，編譯

cd ~/opencv-3.0.0-rc1mkdir releasecd releasecmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..makesudo make install

mkdir ~/opencv-lenacd ~/opencv-lenagedit DisplayImage.cpp

#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;}

gedit CMakeLists.txt

寫入如下內(nèi)容

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

cd ~/opencv-lenacmake .make

此時opencv-lena文件夾中已經(jīng)產(chǎn)生了可執(zhí)行文件DisplayImage，下載lena.jpg放在opencv-lena下，運行

./DisplayImage lena.jpg

可直接使用apt安裝

sudo apt-get install python-opencvsudo apt-get install python-numpy

測試:

打開python，import cv模塊成功即可。

import cv
