ubuntu14.04行为识别稠密轨迹算法环境配置（OpenCV2.4.2+ffmpeg0.11.1）

这里只说一下环境配置供自己回忆用

先安装依赖包，建议最好是每个包一个一个的进行的安装，这样的话出现问题，容易查找，下面把所需要安装的依赖的包罗列出来（以下包是我总结别人的依赖包进行汇总了一下）：

sudo apt-get install make                        sudo apt-get install automake           sudo apt-get install g++

sudo apt-get install bzip2                      sudo apt-get install python            sudo apt-get install unzip

sudo apt-get install patch                      sudo apt-get install subversion         sudo apt-get install ruby

sudo apt-get install build-essential            sudo apt-get install git-core               sudo apt-get install checkinstall

sudo apt-get install texi2html                  sudo apt-get install libfaac-dev               sudo apt-get install libmp3lame-dev

sudo apt-get install libopencore-amrwb-dev      sudo apt-get install libopencore-amrnb-dev

sudo apt-get install libsdl1.2-dev              sudo apt-get install libtheora-dev             sudo apt-get install libvdpau-dev

sudo apt-get install libvorbis-dev              sudo apt-get install libvpx-dev                sudo apt-get install libx11-dev

sudo apt-get install libxfixes-dev              sudo apt-get install libxvidcore-dev           sudo apt-get install libgtk2.0-dev

sudo apt-get install zlib1g-dev                sudo apt-get install libjpeg-dev                sudo apt-get install libtiff4-dev

sudo apt-get install libjasper-dev           sudo apt-get install libopenexr-dev              sudo apt-get install cmake

sudo apt-get install python-dev              sudo apt-get install python-numpy               sudo apt-get install python-tk

sudo apt-get install libtbb-dev               sudo apt-get install libeigen2-dev              sudo apt-get install libx264-dev 

 sudo apt-get install libqt4-dev            sudo apt-get install libqt4-opengl-dev          sudo apt-get install sphinx-common

sudo apt-get install texlive-latex-extra    sudo apt-get install libv4l-dev               sudo apt-get install libdc1394-22-dev

sudo apt-get install libavcodec-dev       sudo apt-get install libavformat-dev            sudo apt-get install libswscale-dev

sudo apt-get install libpng-dev           sudo apt-get install  libxext-dev
sduo apt-get install yasm

 

在安装以上依赖包时，会有个别依赖包安装不成功，没关系继续安装其他依赖包，等全部安装结束后再回头将未成功安装的依赖包进行安装，此时发现已然能够安装。

 

2.安装FFmpeg

先进行卸载已安装成功的FFmpeg，避免冲突

sudo apt-get remove ffmpeg

sudo apt-get autoremove

解压安装包

 

sudo tar -xvjf ffmpeg-0.11.1.tar.bz2

cd ffmpeg-0.11.1

编译安装

./configure --enable-gpl --enable-nonfree --enable-version3 --enable-shared --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libfaac --enable-libmp3lame --enable-libx264 --enable-libxvid --enable-libvpx --enable-postproc --enable-pthreads --enable-libtheora --enable-x11grab --enable-libvorbis --enable-pic

 

./configure --enable-gpl --enable-nonfree --enable-version3 --enable-shared --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libfaac --enable-libmp3lame --enable-libx264 --enable-libxvid --enable-libvpx

 

./configure --enable-gpl --enable-nonfree --enable-version3 --enable-shared --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libfaac --enable-libmp3lame --enable-libx264 --enable-libxvid --enable-libvpx --enable-postproc --enable-pthreads --enable-libtheora --enable-x11grab --enable-libvorbis --enable-pic

make

sudo make install

3.安装OpenCV

 

sudo tar jxvf OpenCV-2.4.2.tar.bz2 -C /usr/local/
cd /usr/local/
sudo mv OpenCV-2.4.2 opencv
cd opencv
mkdir release
cd release

 

cmake -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -DINSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -DBUILD_EXAMPLES=ON -D 
WITH_QT=ON -D WITH_OPENGL=ON ..

 

make
sudo make install

 

安装后的配置

添加库的路径

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

添加内容

/usr/local/lib

在终端输入命令

sudo ldconfig

设置环境变量

sudo gedit /etc/bash.bashrc

在文件最后加入以下两行并保存：

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

此时重启Ubuntu或重新登录账户，使得OpenCV安装生效

测试OpenCV自带例程

编译程序：

cd /usr/local/opencv/samples/c

chmod +x build_all.sh
./build_all.sh

运行程序：

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

安装结束
