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-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opencv
1) 创建工作目录
mkdir ~/opencv-lenacd ~/opencv-lenagedit displayimage.cpp
2) 编辑如下代码
#include #include
using namespace cv;
int main(int argc, char** argv ){ if ( argc != 2 ) { printf(“usage: displayimage.out \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
