总算在Linux下把OpenNI和OPenCV配置好了，网上对Linux下OpenNI的配置方法讲的很少，而寻找使用OpenNI进行开发的方法更是像大海捞针……连手册里都只字不提，翻了好的资料才算搞定。闲话少说，总结在这和大家一起分享。

一、OPenNI篇

1.软件下载：

(1)OpenNI：http://www.openni.org/Downloads/OpenNIModules.aspx

选择“OpenNI Binaries”->“Unstable”->“...for Ubuntu...”，点击“Download”。

下载完成后解压，cd进入解压后的路径：$ ./install.sh（不记得要不要加sudo了，试一试吧）

(2)SensorKinect：

命令：$git clone https://github.com/avin2/SensorKinect.git

如果没有安装git，则sudo apt-get install之～

过程比较慢，结束后会在当前路径出现一个文件夹SensorKinect，cd进SensorKinect/Platform/Linux/CreateRedist，之后$ ./RedistMaker，这时在上层目录Linux下出现Redist文件夹。此时网上说进该目录$ ./install.sh，但实际上还要进一层目录才有instal.sh文件。但是貌似执行这个需要root权限，我不知道怎么弄，$sudo su后也不行，最后发现还是Redist文件夹里面有一个Final文件夹，里面有一个压缩包Sensor-Bin-Linux-x86-v5.0.5.1.tar.bz2，我索性把它拷出来，解压缩后进去（…/SensorKinect/Platform/Linux/CreateRedist/Sensor-Bin-Linux-x86-v5.0.5.1/），在里面$./install.sh，竟然就可以了。顺便说一下，可能在这些过程中输入$ ./install.sh 会提示没有命令之类的，可以在install.sh文件上右击->属性->权限，选中“允许以程序执行文件”，就可以了。

这时可以到在OpenNI-Bin-XXXX/Samples/Bin/x86-Release目录中测试：$ ./NiViewer，有可能提示没有什么库之类的，试着装一下：$sudo apt-get install libusb-1.0-0-dev freeglut3-dev，之后应该就可以运行了，就可以看到期待已久的画面喽。如果这时候提示说Failed to set USB interface!或者Open failed: The network connection has been closed!，在命令行里运行：

$sudo rmmod gspca_kinect

这是因为Ubuntu可能自带了kinect驱动gspca_kinect，二者有冲突。貌似每次重启电脑后都需要执行一下这句才行。如果不想这么麻烦，可以把这个驱动加入系统黑名单：

$sudo gedit /etc/modprobe.d/blacklist.conf

在打开的文件底部加入一行：

blacklist gspca_kinect

这部分主要参考了https://github.com/avin2/SensorKinect里面讲的可能和实际不太一样，尝试着来吧。

(2)NITE：http://www.openni.org/Downloads/OpenNIModules.aspx

选择“OpenNI Compliant Middleware Binaries”->“Unstable”->“...Ubuntu...”，下载就好了。

下载完成后解压，进入目录$ ./install.sh即可。

2.开发环境配置

我选用的是eclipse-cdt进行开发，网上仅有的可怜的一点资料讲的是用codeblocks进行开发，其实都是差不多的。这里以eclipse为例介绍一下吧。

新建一个空的或helloworld工程，如kinectOpenNI，在左侧的project exploer中右击kinectOpenNI，点properties，在对话框中选择C/C++ Build->settings->GCC C++ Compiler(如果用C写就选GCC C Compiler)->Directories，在右侧Include paths(-l)里点右边绿色加号，添加两个路径/usr/include/ni和/usr/include/nite，然后再选择GCC C++ Linker->Libraries，在Libraries (-l)中添加OpenNI，glut，XnVNite，注意XnVNite可能有版本号，要到你的/usr/lib目录下看一看，有个文件叫libXnVNite_XXXX.so之类的，我的是libXnVNite_1_5_0.so，所以我填的是XnVNite_1_5_0，反正就是随机应变吧，填不对的话它会报错说找不到库。由于这几个库都是在系统/usr/lib/目录下的，因此不用添加Library search path (-L)。

到此为止你的工程应该可以编译了。试试这段样例：(注意该一下里面xml文件的路径。样例是直接从安装包里找到的。当然，记得连上你的Kinect)

二、OpenCV篇

虽然已经可以用OpenGL了，但是OpenCV还是很不错的，也配一下吧。

1.软件下载

(1)装一下这些吧：

apt-get install build-essential

apt-get install cmake cmake-gui

apt-get install pkg-config

apt-get install libpng12-0 libpng12-dev libpng++-dev libpng3

apt-get install libpnglite-dev libpngwriter0-dev libpngwriter0c2

apt-get install zlib1g-dbg zlib1g zlib1g-dev

apt-get install libjasper-dev libjasper-runtime libjasper1

apt-get install pngtools libtiff4-dev libtiff4 libtiffxx0c2 libtiff-tools

apt-get install libjpeg8 libjpeg8-dev libjpeg8-dbg libjpeg-prog

apt-get install ffmpeg libavcodec-dev libavcodec52 libavformat52 libavformat-dev

apt-get install libgstreamer0.10-0-dbg libgstreamer0.10-0libgstreamer0.10-dev

apt-get install libxine1-ffmpeglibxine-dev libxine1-bin

apt-get install libunicap2 libunicap2-dev

apt-get install libdc1394-22-dev libdc1394-22 libdc1394-utils

apt-get install swig

apt-get install libv4l-0 libv4l-dev

apt-get install python-numpy

apt-get install libpython2.6 python-dev python2.6-dev

有些可能你用不到，但是貌似build-essential,cmake,pkg-config都是必须的，其他的都不确定啦，保险起见都装一下吧～

(2)下载最新版本OpenCV：http://sourceforge.net/projects/opencvlibrary/files/

解压，生成目录如OpenCV-2.3.1，在它旁边新建一个目录，如OpenCV-2.3.1-build。这时打开cmake-gui图形界面，应该可以在主菜单的“编程”项中找到。在上面的Source和Build栏中分别填上OpenCV-2.3.1和OpenCV-2.3.1-build的完整路径。点下面的Config，如果窗口内容变红，再点一次，知道不红为止，这时点Generate即可。命令行cd进OpenCV-2.3.1-build，$make然后$sudo make install，此时OpenCV应该就被安装在/usr/local/下面了。

2.建立工程

使用eclipse建立新工程，如testOpenCV在左侧的project exploer中右击testOpenCV，点properties，在对话框中选择C/C++ Build->settings->GCC C++ Compiler(如果用C写就选GCC C Compiler)->Directories，在右侧Include paths(-l)里点右边绿色加号，添加路径/usr/local/include/opencv，然后再选择GCC C++ Linker->Libraries，在Libraries (-l)中添加opencv_core，opencv_highgui，如果需要其他库也依次添加。库的路径是/usr/local/lib，因此要添加Library search path (-L)：/usr/local/lib。

还要给系统添加一下环境变量。我是试了好几种方法，也不知道最后是那个生效了：

命令行里依次输入（就是新建个文件，添上一行/usr/local/lib，也可以用gedit来做）：

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

/usr/local/lib

<Esc>

:wq!

类似地，打开文件/etc/bash.bashrc，在最后添加两行：

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

export PKG_CONFIG_PATH

然后在命令行输入：

sudo ldconfig -v

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
