宅宅情侶的成長日記

一、軟體安裝

下載opencv_2.4.8

 網址：http://opencv.org/

二、套件安裝

$sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg62-dev

libtiff4-dev cmake libswscale-dev libjasper-dev

If it cannot find the ffmpeg's download site, please update your Ubuntu first.

三、OpenCV建置

$unzip opencv-2.4.8.zip

沒有unzip時 -> $sudo apt-get install unzip

#Build Makefile && Install

$cd opencv-2.4.8/

$cmake .  #cmake執行完會產生Makefile

$make

$sudo make install

#Open the opencv.conf file -> $sudo nano /etc/ld.so.conf.d/opencv.conf

在opencv.conf裡面寫入 /usr/local/lib ， 寫完之後存檔離開

#Configure

$sudo ldconfig

$sudo nano /etc/bash.bashrc

在最底下加入

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

export PKG_CONFIG_PATH

#Build sample

$cd opencv-2.4.8/samples/c

$sudo chmod +x build_all.sh

$sudo ./build_all.sh

$sudo ./facedetect --cascade="/usr/local/share/OpenCV/haarcascades/haarcascades_frontalface_alt.xml"
