optris PI450 ros版在ubuntu下的安装
参考官网
https://wiki.ros.org/optris_drivers
安装教程http://documentation.evocortex.com/libirimager2/html/Installation.html
一步一步做下来，make还是cmake的时候疯狂报错
而且看起来不是缺包是代码的错（redefinition）
搜了一下google和github好像也没有什么人遇到过。
不想改了，改用/example/python下面的python版吧。
再写个ros topic的listener和talker就行了。
后面补充……
注意：镜头是可以拧的来调焦，我以为是程序哪里需要设分辨率还改了好久。。。。
分享迷惑
补充
换了个电脑重新安装了一次，几个新问题
1、sudo usermod -a -G video 这个命令以后要重启才能生效，groups后能看到新添加的vedio
2、sudo ir_download_calibration这一步可能卡住很久，大概是因为网络的问题，可以直接拷贝到指定目录下
3、c++版的irviewer是/example/oop文件夹下的，make时可能会报错

解决办法，改CMakeList，这一行加上-std=c++11
SET(CMAKE_CXX_FLAGS "-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -std=c++11 -D_GLIBCXX_USE_CXX11_ABI=0")
之前遇到的那个redefinition的问题，换了个电脑就好了。。。。
4、python版的节点也写好了
pub_ir_image.py
可以供参考，其实就是把之前的代码复制过来再加一个topic发布

try:

except rospy.ROSInterruptException:

然后自己加上CMakelist和package.xml再catkin_make后
直接
rosrun test_py pub_ir_image.py
就可以了！
