Ubuntu下安装配置OpenNI, OpenCV 步骤
费了老大半天工夫,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: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:$ 不记得要不要加sudo了,试一试吧)
(2)SensorKinect:
命令:$git clone
如果没有安装git,则sudo apt-get install之~
过程比较慢,结束后会在当前路径出现一个文件夹SensorKinect,cd进SensorKinect/Platform/Linux/CreateRedist,之后$ 这时在上层目录Linux下出现Redist文件夹。此时网上说进该目录$ 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,$sudo su后也不行,最后发现还是Redist文件夹里面有一个Final文件夹,里面有一个压缩包Sensor-Bin-Linux-x86-v5.0.5.1.tar.bz2,我索性把它拷出来,解压缩后进去 (…/SensorKinect/Platform/Linux/CreateRedist/Sensor-Bin-Linux-x86-v5.0.5.1/),在里面$竟然就可以了。顺便说一下,可能在这些过程中输入$ 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:$ 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:
$sudo rmmod gspca_kinect
这是因为Ubuntu可能自带了kinect驱动gspca_kinect,二者有冲突。貌似每次重启电脑后都需要执行一下这句才行。
这部分主要参考了里面讲的可能和实际不太一样,尝试着来吧。
(2)NITE:
选择“OpenNI Compliant Middleware Binaries”->“Unstable”->“…Ubuntu…”,下载就好了。
下载完成后解压,进入目录$ 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)
