Ubuntu 14.04下OpenCV 3.0+Python 2.7安装测试

本文记录了Ubuntu 14.04下使用源码手动安装OpenCV 3.0的过程。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）

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

[compiler] sudo apt-get install build-essential
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev2、从官网下载最新opencv源码（2.4以上）http://sourceforge.net/projects/opencvlibrary/或者github3、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-rc1
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install4、测试opencv1）创建工作目录mkdir ~/opencv-lena
cd ~/opencv-lena
gedit DisplayImage.cpp2）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> "）;
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;
}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-lena
cmake .
make5）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.jpg6）结果5、安装python-opencv可直接使用apt安装sudo apt-get install python-opencv
sudo apt-get install python-numpy测试:打开python，import cv模块成功即可。import cv--------------------------------------分割线 --------------------------------------Ubuntu Linux下安装OpenCV2.4.1所需包 http://www.linuxidc.com/Linux/2012-08/68184.htmUbuntu 12.04 安装 OpenCV2.4.2 http://www.linuxidc.com/Linux/2012-09/70158.htmCentOS下OpenCV无法读取视频文件 http://www.linuxidc.com/Linux/2011-07/39295.htmUbuntu 12.04下安装OpenCV 2.4.5总结 http://www.linuxidc.com/Linux/2013-06/86704.htmUbuntu 10.04中安装OpenCv2.1九步曲 http://www.linuxidc.com/Linux/2010-09/28678.htm基于QT和OpenCV的人脸识别系统 http://www.linuxidc.com/Linux/2011-11/47806.htm[翻译]Ubuntu 14.04, 13.10 下安装 OpenCV 2.4.9 http://www.linuxidc.com/Linux/2014-12/110045.htm--------------------------------------分割线 --------------------------------------OpenCV的详细介绍：请点这里
