Intro

單純用 library 的話

sudo apt-get install libopencv-dev

其它安裝方法
基本上, 完全照著文章做, 這邊留記錄

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen3-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev default-jdk ant libvtk5-qt4-dev

Content

cd ~
wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.9/opencv-2.4.9.zip
unzip opencv-2.4.9.zip
cd opencv-2.4.9

Build的時間有點長

mkdir build
cd build
cmake -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 -D WITH_VTK=ON ..

build好可以安裝了

make
sudo make install

安裝完後可以設定OpenCV

sudo gedit /etc/ld.so.conf.d/opencv.conf

在這個Config檔中加入下面這行(它可能是空的, 那是OK的)然後儲存它

/usr/local/lib

用這個來設定library

sudo ldconfig

開啟這個檔案

sudo gedit /etc/bash.bashrc

在最後加入下述兩行

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

最後重啟你的電腦
後面有些Sample可以執行來看看



到解壓縮的路徑下執行sample程式

cd ~/opencv-2.4.9/samples/c
chmod +x build_all.sh
./build_all.sh

./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascade_frontalface_alt.xml" --scale=1.5 lena.jpg
