在Ubuntu中安装并测试OpenCV

参照www.Micro_Studios.com的视频&＃xff0c;在Ubuntu中成功安装了opencv&＃xff0c;并且测试成功。现把具体的安装及测试过程整理出来&＃xff0c;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:

sudo apt-get update
sudo apt-get upgrade


(2) Remove previously installedFFMPEG and x264 libraries:

sudo apt-get remove ffmpeg x264-dev

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

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:

mkdir opencv
cd opencv

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

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

(6) Create a directory to compileOpenCV sources:

mkdir build
cd build

(7) Building OpenCV sources withCMake and install:

cmake -D CMAKE_BUILD_TYPE&＃61;RELEASE -D CMAKE_INSTALL_PREFIX&＃61;/usr/local -D WITH_TBB&＃61;ON -D INSTALL_PYTHON_EXAMPLES&＃61;ON -D BUILD_EXAMPLES&＃61;ON -D WITH_QT&＃61;ON -D WITH_OPENGL&＃61;ON ..

(8) Make and install:

make
sudo make install
sudo sh -c &＃39;echo"/usr/local/lib">/etc/ld.so.conf.d/opencv.conf&＃39;
sudo ldconfig                     

(9) Restart the system for everythingto take effect:

sudo shutdown -r now

2. Test OpenCV in Ubuntu:

(1) Create a directory DisplayImagefor test project:

mkdir DisplayImage
cd DisplayImage

(2) Create DisplayImage.cpp and edit it:

gedit DisplayImage.cpp

Then edit the DisplayImage.cpp:

#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("Noimage data\n");return -1;}namedWindow("DisplayImage",CV_WINDOW_AUTOSIZE);imshow("DisplayImage",image);waitKey(0);return 0;
}

(3) Create a CMake file:

gedit CMakeLists.txt

Then edit the CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)
project(DisplayImage)
find_package(OpenCV REQUIRED)
add_executable(DisplayImage DisplayImage.cpp)
target_link_libraries(DisplayImage ${OpenCV_LIBS})

(4) Generate the executable file:

cmake .
make

(5) Execute it:

./DisplayImage lena.jpglena.jpg is the test image
