Инсталация openCV
1. Инсталирайте cmake sudo apt-get install cmake
2. Инсталирайте библиотеката libgtk2.0-dev
sudo apt-get install libgtk2.0-dev
3. да се свали openCV 2.2 и разархивирайте в директория Downloads/OpenCV-2.2.0
4. Влезте в директорията
cd Downloads/OpenCV-2.2.0 cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ./ make make install
export LD_LIBRARY_PATH=/home/lab/Downloads/OpenCV-2.2.0/lib:$LD_LIBRARY_PATH sudo ldconfig

{
CvCapture* c1 = cvCaptureFromCAM(0);
IplImage* img = 0;
while(cvWaitKey(2) < 0)
{
cvGrabFrame( c1 );
img=cvRetrieveFrame(c1,0);
cvShowImage( "c1", img);
}
//destroy the window
cvReleaseCapture(&c1);
return 0;
}
