Ubuntu14 系统下安装Opencv3.0攻略

Ubuntu14 系统下安装Opencv3.0攻略

安装准备

安装环境： Ubuntu14.0系统

安装软件: OpenCV3.0.0 linux版本

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

如果没有，可以现在输入以下指令

[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

安装流程

1.更新系统

利用ubuntu自带的更新管理器或者
sudo apt-get update
sudo apt-get upgrade

2.安装依赖包。否则写OpenCV程序的时候虽然编译能通过，可能运行时出错。

sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev cmake libswscale-dev libjasper-dev

3下载openCV的源码包并解压出来

下载地址: http://sourceforge.net/projects/opencvlibrary/

解压文件：/home/workplace/opencv3.0

进入当前Opencv的文件 cd ~/opencv

创建一个文件 mkdir release

cd release

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..[网上攻略多是这条的指令]

[但是限量版在安装过程中主要是被这条指令给坑惨了]

这条指令可能会带来以下问题。。。

可能遇到的问题：

Scanning dependencies of target opencv_core[ 10%] Building CXX object modules/core/CMakeFiles/opencv_core.dir/src/system.cpp.o

Linking CXX shared library ../../lib/libopencv_core.so

[ 15%] Built target opencv_core

/usr/bin/ld: final link failed: Bad value

collect2: ld returned 1 exit status

make[2]: *** [lib/libopencv_imgproc.so.3.0.0] Error 1

make[1]: *** [modules/imgproc/CMakeFiles/opencv_imgproc.dir/all] Error 2

make: *** [all] Error 2

主要原因是，WITH_OFF开启了会有一定冲突

解决办法: cmake时添加-D WITH_IPP=OFF即可

完整命令：cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX= /usr/local/ -D WITH_IPP=OFF ../

4. 在release目录下

输入sudo make指令

5. sudo make install

6. 编译samples程序：

$ cd ~/opencv/samples

$ sudo cmake .

$ sudo make -j $(nproc)

测试安装结果

1) 创建工作目录

mkdir ~/opencv-lena
cd ~/opencv-lena
gedit 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-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，下载lena.jpg放在opencv-lena下，运行

./DisplayImage lena.jpg

6)结果
