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&＃xff08;编译器、必须库、可选库&＃xff09;
- GCC 4.4.x or later
- CMake 2.6 or higher
- Git
- GTK&＃43;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
2、从官网下载最新opencv源码&＃xff08;2.4以上&＃xff09;
http://sourceforge.net/projects/opencvlibrary/
或者github
3、编译opencv
将opencv放至任意目录&＃xff0c;解压
unzip opencv-3.0.0-rc1.zip
创建编译目录&＃xff0c;编译
cd ~/opencv-3.0.0-rc1
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE&＃61;RELEASE -D CMAKE_INSTALL_PREFIX&＃61;/usr/local ..
make
sudo make install
4、测试opencv
1) 创建工作目录
mkdir ~/opencv-lena
cd ~/opencv-lena
gedit DisplayImage.cpp
2) 编辑如下代码
#include
#include using namespace cv;int main(int argc, char** argv )
{if ( argc !&＃61; 2 ){printf("usage: DisplayImage.out \n");return -1;}Mat image;image &＃61; 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
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 .
make
5) 执行
此时opencv-lena文件夹中已经产生了可执行文件DisplayImage&＃xff0c;下载lena.jpg放在opencv-lena下&＃xff0c;运行
6) 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&＃xff0c;import cv模块成功即可。
import cv参考
