ubuntu12.04+Eclipse+opencv环境搭建与配置

ゝ一世哀愁。 2022-07-24 07:06 168阅读 0赞

1.下载并安装Eclipse+cdt,这个很简单。

2.下载linux版的opencv:[http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.6.1/opencv-2.4.6.1.tar.gz/download][http_sourceforge.net_projects_opencvlibrary_files_opencv-unix_2.4.6.1_opencv-2.4.6.1.tar.gz_download]

3.然后安装依赖包：

sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen2-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev

4.下载cmake:sudo apt-get install cmake

5.解压下载的opencv,进入该目录创建build文件夹：

cd OpenCV-2.4.6.1

mkdir build

cd build

6.一次运行：

cmake .. (注意该命令为cmake空格后面两个点)

make

sudo make install

这一步需要较长时间，请耐心等待。

7.`现在需要配置必要的库。运行 ``sudo` `gedit /etc/ld.so.conf.d/opencv.conf`

`添加这句命令到文件中，/usr/``local``/lib`,文件或许是空的，但不影响。

8.运行此命令  `sudo` `ldconfig`

`9.运行此命令：``sudo` `gedit /etc/``bash``.bashrc 然后添加下面两行到文件的末尾并保存：`

`PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH`

`10.打开Eclipse并新建工程进行测试，以下是步骤：`

`10.1打开Eclipse,选择File->New->C Project`

然后输入工程名字和存放地址，选择Executable->Empty Project,其他的都选默认即可，点击Finish.

10.2对工程进行配置，主要时包含的目录和库文件

10.2.1选择Project–>Properties

在C/C++ Build下选择Settings. 在右侧选择Tool Settings Tab. 然后输入我们的头文件包含目录：

(a).选择GCC C++ Compiler->Includes. 在Include paths(-l) 你选择你安装的include路径，我安装在/usr/local/include/opencv.

[![ubuntu12.04+Eclipse+opencv环境搭建与配置][ubuntu12.04_Eclipse_opencv 1]][ubuntu12.04_Eclipse_opencv_ubuntu12.04_Eclipse_opencv 1]  
这里一定要填两个路径：/usr/local/include和/usr/local/include/opencv.

Note:要是你不知道安装在那个路径，输入如下命令：pkg-config --cflags opencv

我的结果为：-I/usr/local/include/opencv -I/usr/local/include

(b).然后进入GCC C++ Linker,这里有两个地方要输入：

首先在Library search path (-L) 你必须输入你安装的opencv库目录，我的路径是/usr/local/lib

然后在Libraries(-l) 添加你所需要的库，通常有三个是你必须的，一下是一些常见的：

opencv\_core opencv\_imgproc opencv\_highgui opencv\_ml opencv\_video opencv\_features2d

opencv\_calib3d opencv\_objdetect opencv\_contrib opencv\_legacy opencv\_flann

[![ubuntu12.04+Eclipse+opencv环境搭建与配置][ubuntu12.04_Eclipse_opencv 2]][ubuntu12.04_Eclipse_opencv_ubuntu12.04_Eclipse_opencv 2]  
Note如果你不知道安装的目录，输入一下命令：pkg-config --libs opencv

10.3好了，现在可以写代码了，选咋New->Source File：test.c,然后Finish.我的测试代码如下：

\#include

int main( int argc, char\*\* argv )

IplImage\* img;

img=cvLoadImage("lena.jpg",1);

cvNamedWindow("hello",1);

cvShowImage("hello",img);

cvWaitKey(0);

cvReleaseImage(&img);

cvDestroyWindow("hello");

return 0;

把lena.jpg考入你的工程目录下即可，测试结果如图：

ok,配置这里结束，在这个过程中也遇到了不少问题，但都一一得到了解决，一下是我用过的一些网站：
