准備工作，Ubuntu下安裝Eclipse和CDT。在這裡就不說了，參考 http://www.linuxidc.com/Linux/2011-01/31367.htm 。
下面主要說一下集成OpenCV
1：安裝OpenCV 可以看OpenCv的安裝 http://www.linuxidc.com/Linux/2012-12/75641.htm 默認的安裝目錄是/usr/local/include
2：新建一個C++項目。首先右鍵點擊新建的項目，在項目屬性的C++ Build->Settings，這裡要對編譯器參數進行設置。在GCC C++ Compiler->Directories的include paths中新增一個/usr/local/include/opencv；和/usr/local/include/opencv2
3:終端輸入
pkg-config --libs opencv
我的顯示如下
/usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so
這樣就意味著：
找到 GCC C++ Linker，在右側 First in Library search path (-L) 中加入這些庫
注意：
在eclipse中添加庫時，usr/local/lib中是libopencv_***，在eclipse裡添加為opencv_***，大小寫敏感。
