参照www.Micro_Studios.com的视频，在Ubuntu中成功安装了OpenCV，并且测试成功。现把具体的安装及测试过程整理出来，适合刚刚在Linux中使用opencv的同学参考参考。

1. Install OpenCV in Ubuntu:

 

(1) Update the list of packagerepositories:

[plain] view plain copy

1. sudo apt-get update  
2. sudo apt-get upgrade  

(2) Remove previously installedFFMPEG and x264 libraries:

[plain] view plain copy

1. sudo apt-get remove ffmpeg x264-dev  

(3) Installthe necessary packages for compiling the OpenCV sources:

[plain] view plain copy

1. sudo apt-get install ocl-icd-libopencl1 build-essential checkinstall cmake pkg-config yasm libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev  libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils  

(4) Make a directory to downloadand build OpenCV:

[plain] view plain copy

1. mkdir opencv  
2. cd opencv  

(5) Download the OpenCV sources forLinux, then unzip it:

[plain] view plain copy

1. wget -O opencv-2.4.10.zip http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.10/opencv-2.4.10.zip/download  
2. unzip opencv-2.4.10.zip  
3. cd opencv-2.4.10  

(6) Create a directory to compileOpenCV sources:

[plain] view plain copy

1. mkdir build  
2. cd build  

(7) Building OpenCV sources withCMake and install:

[plain] view plain copy

1. cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..  

(8) Make and install:

[plain] view plain copy

1. make  
2. sudo make install  
3. sudo sh -c 'echo"/usr/local/lib">/etc/ld.so.conf.d/opencv.conf'  
4. sudo ldconfig  

                     

(9) Restart the system for everythingto take effect:

[plain] view plain copy

1. sudo shutdown -r now  

2. Test OpenCV in Ubuntu:

 

(1) Create a directory DisplayImagefor test project:

[plain] view plain copy

1. mkdir DisplayImage  
2. cd DisplayImage  

(2) Create DisplayImage.cpp and edit it:

[plain] view plain copy

1. gedit DisplayImage.cpp  

Then edit the DisplayImage.cpp:

[cpp] view plain copy

1. #include <stdio.h>  
2. #include <opencv2/opencv.hpp>  
3. using namespace cv;  
4.    
5. int main(int argc, char** argv)  
6. {  
7.          if(argc!= 2)  
8.          {  
9.                    printf("usage:DisplayImage.out <Image_Path>\n");  
10.                    return -1;  
11.          }  
12.    
13.          Mat image;  
14.          image= imread(argv[1], 1);  
15.    
16. <span style="white-space:pre">    </span>if(!image.data)  
17. <span style="white-space:pre">    </span>{  
18.                    printf("Noimage data\n");  
19.                    return -1;  
20.          }  
21.    
22.          namedWindow("DisplayImage",CV_WINDOW_AUTOSIZE);  
23.          imshow("DisplayImage",image);  
24.    
25.          waitKey(0);  
26.          return 0;  
27. }  

(3) Create a CMake file:

[plain] view plain copy

1. gedit CMakeLists.txt  

Then edit the CMakeLists.txt:

[plain] view plain copy

1. cmake_minimum_required(VERSION 2.8)  
2. project(DisplayImage)  
3. find_package(OpenCV REQUIRED)  
4. add_executable(DisplayImage DisplayImage.cpp)  
5. target_link_libraries(DisplayImage ${OpenCV_LIBS})  

(4) Generate the executable file:

[sql] view plain copy

1. cmake .  
2. make  

(5) Execute it:

[plain] view plain copy

1. ./DisplayImage lena.jpg  

lena.jpg is the test image
