今天帮实验室同学在ubuntu下安装了opencv，现在将详细步骤记录如下：1、在终端输入并运行sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup （备份当前的源列表，以便日後需要时恢复）sudo gedit /etc/apt/sources.list （修改sources.list文件中源的列表）弹出文本后在sources.list文件中，把原来的源全部删除，然后把下面的源添加进去：我采用网易163源，速度还不错，如下：deb
http://mirrors.163.com/ubuntu/ intrepid main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ intrepid-security main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ intrepid-updates main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ intrepid-proposed main restricted universe multiversedeb
http://mirrors.163.com/ubuntu/ intrepid-backports main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ intrepid main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ intrepid-security main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ intrepid-updates main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ intrepid-proposed main restricted universe multiversedeb-src
http://mirrors.163.com/ubuntu/ intrepid-backports main restricted universe multiverse2、保存编辑好的文件，执行以下命令更新。sudo apt-getupdate #这一步是更新你的源列表，换源后必须执行3、解压openCV2.1
tar
xjf OpenCV-2.1.0.
tar
.bz2
4、更新完之后，执行如下命令
huanghuang@huanghuang-desktop:~$sudo
apt-get
install
build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev libtiff4-dev cmake libswscale-dev libjasper-dev
5、huanghuang@huanghuang-desktop:/$ cd /opencv-linux/OpenCV-2.1.0
huanghuang@huanghuang-desktop:/opencv-linux/OpenCV-2.1.0$
6、huanghuang@huanghuang-desktop:/opencv-linux/OpenCV-2.1.0$ cmake .
7、make
sudo make install
8、sudo
[code]gedit /etc/ld.so.conf.d/opencv.conf
里面为空文档，在其中添加
/usr/
local
/lib，然后保存。
9、
配置库执行，sudo
ldconfig
10、
sudo
gedit /etc/
bash
.bashrc
打开，在其最后添加
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/
local
/lib/pkgconfig
export
PKG_CONFIG_PATH
保存退出。
11、check some demos：
2 | cp /opencv-linux/OpenCV-2.1.0/samples/c/* /openCV_samples |
12、huanghuang@huanghuang-desktop:/openCV_samples$ ls0 fback.cpp motempl.cadaptiveskindetector ffilldemo mser_sampleadaptiveskindetector.cpp ffilldemo.c mser_sample.cppagaricus-lepiota.data find_obj mushroomairplane.jpg find_obj_calonder mushroom.cppbaboon200.jpg find_obj_calonder.cpp one_way_sample.cppbaboon200_rotated.jpg find_obj.cpp one_way_train_0000.jpgbaboon.jpg find_obj_ferns one_way_train_0001.jpgbgfg_codebook find_obj_ferns.cpp peopledetectbgfg_codebook.cpp fitellipse peopledetect.cppbgfg_segm fitellipse.cpp pic1.pngbgfg_segm.cpp fruits.jpg pic2.pngblobtrack grabcut pic3.pngblobtrack.cpp grabcut.cpp pic4.pngbox_in_scene.png houghlines pic5.pngbox.png houghlines.c pic6.pngbuild_all.sh image polar_transformscalibration image.cpp polar_transforms.ccalibration_artificial inpaint puzzle.pngcalibration_artificial.cpp inpaint.cpp pyramid_segmentationcalibration.cpp kalman pyramid_segmentation.ccamshiftdemo kalman.c right01.jpgcamshiftdemo.c kmeans right02.jpgCMakeLists.txt kmeans.c right03.jpgcontours laplace right04.jpgcontours.c laplace.c right05.jpgconvert_cascade left01.jpg right06.jpgconvert_cascade.c left02.jpg right07.jpgconvexhull left03.jpg right08.jpgconvexhull.c left04.jpg right09.jpgcvsample.dsp left05.jpg right11.jpgdelaunay left06.jpg right12.jpgdelaunay.c left07.jpg right13.jpgdemhist left08.jpg right14.jpgdemhist.c left09.jpg scene_l.bmpdft left11.jpg scene_r.bmpdft.c left12.jpg squaresdistrans left13.jpg squares.cdistrans.c left14.jpg stereo_calibdrawing lena.jpg stereo_calib.cppdrawing.c letter_recog stereo_calib.txtedge letter_recog.cpp stereo_matchedge.c letter-recognition.data stereo_match.cppexample_cmake lkdemo stuff.jpgfacedetect lkdemo.c tree.avifacedetect.cmd minarea tree_enginefacedetect.cpp minarea.c tree_engine.cppfback morphology watershedfback_c morphology.c watershed.cppfback_c.c motempl waveform.data13、huanghuang@huanghuang-desktop:/openCV_samples$ ./grabcut lena.jpg[/code]14、试下摄像头。。huanghuang@huanghuang-desktop:/openCV_samples$ ./camshiftdemo效果不错，呵呵！15、为了方便使用，我把它做到桌面的图标，类似于windows下面的图标。如下：这样一点击就去可以用了，要退出只要在终端中用ctrl+c。
