安装环境：ubuntu12.04 + fuerte
1、执行$sudo apt-get install ros-fuerte-openni-kinect。
2、执行$roscore。在ros环境下。
3、执行$roslaunch openni_launch openni.launch，执行openni的节点，判断有没有安装成功。
（这一步本人测试没有遇到过。因为查询lsusb -v |grep 601是查到的，说明硬件版本是新版本。）
结果出现了如下错误：
显示no device connected,也就是驱动没装好。经查证，xtion prolive是有2个版本的，一个是旧版本，可以支持很多ROS，另一种版本是新版本，安装了之前的命令后就会出现驱动没装好。执行$ lsusb–v 就可以知道摄像头的版本信息。
4、执行$sudo apt-get install --reinstall libopenni-sensor-primesense0。安装新版本的xtion pro live。本人没有操作这一步。
5、再次执行$ roslaunch openni_launch openni.launch。
出现的错误：

仔细看以上的错误，发现USB接口有问题。
6、执行$sudo gedit /etc/openni/GlobalDefaults.ini。
找到内容为“；UsbInterface=2”这一行，将这行更改为UsbInterface=0，注意去掉分号注释。
7、再次执行$roslaunch openni_launch openni.launch。

8、执行$rosrun image_view image_view image:=/camera/rgb/image_color，就会看到摄像头采集的图片。到达这一步是ok的。
9、深度显示
运行以下节点：
rosrun image_view disparity_view image:=/camera/depth/disparity 可以看到视差图像。
rosrun rviz rviz 可以在rviz窗口查看。但需要进行rviz.cfg配置。指定配置文件或创建临时文件，然后设置参数。
修改某些参数即可显示图像。
