Ubuntu14.04+opencv 3.0+python2.7安装及测试本文记录了ubuntu下使用源码手动安装opencv的过程。步骤来自opencv官网
此外记录了在python中安装及载入opencv的方法。
1、安装opencv所需的库（编译器、必须库、可选库）转载请说明http://www.cnblogs.com/llxrl/p/4471831.html
GCC 4.4.x or laterCMake 2.6 or higherGitGTK+2.x or higher, including headers (libgtk2.0-dev)pkg-configPython 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-dev1 [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
2、从官网下载最新opencv源码（2.4以上）http://sourceforge.net/PRojects/opencvlibrary/
或者github
3、编译opencv将opencv放至任意目录，解压
unzip opencv-3.0.0-rc1.zip
创建编译目录，编译
cd ~/opencv-3.0.0-rc1mkdir releasecd releasecmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..makesudo make install
4、测试opencv1) 创建工作目录mkdir ~/opencv-lenacd ~/opencv-lenagedit DisplayImage.cpp
2) 编辑如下代码#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) 创建CMake编译文件gedit CMakeLists.txt
写入如下内容
cmake_minimum_required(VERSION 2.8)project( DisplayImage )find_package( OpenCV REQUIRED )add_executable( DisplayImage DisplayImage.cpp )target_link_libraries( DisplayImage ${OpenCV_LIBS} )
4) 编译cd ~/opencv-lenacmake .make
5) 执行此时opencv-lena文件夹中已经产生了可执行文件DisplayImage，下载lena.jpg放在opencv-lena下，运行
./DisplayImage lena.jpg
6) 结果
5、安装python-opencv可直接使用apt安装
sudo apt-get install python-opencvsudo apt-get install python-numpy
测试:
打开python，import cv模块成功即可。
import cv
