آموزش نصب OpenCV 2.4.9 در کوبونتو ۱۴.۰۴
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
sudo apt-get install cmake cmake-qt-gui git
sudo apt-get install openjdk-7-jre
sudo apt-get install apt-build
sudo apt-get install qtcreator
sudo apt-get install libqtwebkit4 qt4-dev-tools
sudo apt-get install libopencv-dev checkinstall 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
wget http://citylan.dl.sourceforge.net/project/opencvlibrary/opencv-unix/2.4.9/opencv-2.4.9.zip
unzip opencv-2.4.9.zip
cd opencv-2.4.9
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
sudo make -j4
sudo make install
sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
حالا ریستارت کنید
cd /usr/local/share/OpenCV/samples/c
sudo chmod +x build_all.sh
sudo ./build_all.sh
./pyramid_segmentation baboon.jpg
اگر عکس بابون را دیدید یعنی به دستی نصب شده

آزمایش درستی نصب با اجرای برنامه خودتان
برنامه اول - تست عکس
فایل CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(first)
FIND_PACKAGE(OpenCV REQUIRED core highgui)
add_executable(first main.cpp)
TARGET_LINK_LIBRARIES(first ${OpenCV_LIBS})
فایل main.cpp
#include <iostream>
#include <opencv2/highgui/highgui.hpp>
using namespace std;
using namespace cv;
Mat im;
int main(int argc, char **argv)
{
if (argc!=2)
{
cout << "\nYou must enter an image.\n\n";
return -1;
}
im = imread(argv[1], CV_LOAD_IMAGE_COLOR);
namedWindow("First Program");
imshow("First Program", im);
cout << "Press 'q' to quit.\n\n";
while(1)
{
if(waitKey(1) == 'q') break;
}
destroyAllWindows();
return 0;
}
نحوه کامپایل و اجرا
mkdir build
cd build
cmake ..
make
./first ~/Pictures/test.jpg
برنامه دوم - تست ویدئو
فایل CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(second)
FIND_PACKAGE(OpenCV REQUIRED core highgui)
add_executable(second main.cpp)
TARGET_LINK_LIBRARIES(second ${OpenCV_LIBS})
فایل main.cpp
#include <iostream>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main(int argc, char **argv)
{
if (argc!=2)
{
cout << "\nYou must enter a video.\n\n";
return -1;
}
VideoCapture cap(argv[1]); // Create a VideoCapture object to read from video file
if(!cap.isOpened()) //check if the file was opened
{
cout << "\nCapture could not open this video\n\n";
return -1;
}
Mat frame;
namedWindow("Second Program");
while(cap.isOpened())
{
cap >> frame;
if(frame.empty()) // Check if the video is over
{
cout << "\nEnd!\n\n";
break;
}
imshow("Second Program", frame);
waitKey(100);
}
cout << "Press a key to quit.\n\n";
waitKey(0);
destroyAllWindows();
return 0;
}
نحوه کامپایل و اجرا
mkdir build
cd build
cmake ..
make
./scond ~/Videos/test.avi
