系統環境：

ubuntu16.04 

qt5.6.2

opencv3.0

1、下載安裝好依賴環境：

sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev	
 

3、編譯opencv，將opencv3.0解壓到任意資料夾，然後進入opencv3.0的資料夾

mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make 
sudo make install

4、使用qt建立一個專案，在QT中的.pro檔案中新增下面的連結庫就行了：

INCLUDEPATH+=/usr/local/include\
/usr/local/include/opencv\
/usr/local/include/opencv2

LIBS+=/usr/local/lib/libopencv_calib3d.so.3.0\
/usr/local/lib/libopencv_core.so.3.0\
/usr/local/lib/libopencv_features2d.so.3.0\
/usr/local/lib/libopencv_flann.so.3.0\
/usr/local/lib/libopencv_highgui.so.3.0\
/usr/local/lib/libopencv_imgcodecs.so.3.0\
/usr/local/lib/libopencv_imgproc.so.3.0\
/usr/local/lib/libopencv_ml.so.3.0\
/usr/local/lib/libopencv_objdetect.so.3.0\
/usr/local/lib/libopencv_photo.so.3.0\
/usr/local/lib/libopencv_shape.so.3.0\
/usr/local/lib/libopencv_stitching.so.3.0\
/usr/local/lib/libopencv_superres.so.3.0\
/usr/local/lib/libopencv_videoio.so.3.0\
/usr/local/lib/libopencv_video.so.3.0\
/usr/local/lib/libopencv_videostab.so.3.0\
/usr/local/lib/libopencv_viz.so.3.0
