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:
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=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:
make
sudo make install
sudo sh -c 'echo"/usr/local/lib">/etc/ld.so.conf.d/opencv.conf'
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!= 2){printf("usage:DisplayImage.out \n");return -1;}Mat image;image= 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.jpg
lena.jpg is the test image
