Linux下的设备使用都需要使用sudo或root用户才能打开，为了能让普通用户也能使用串口，可以增加udev规则来实现，具体方法如下：sudo vim /etc/udev/rules.d/70-ttyusb.rules增加如下内容：KERNEL=="ttyUSB[0-9]*",MODE="0666"保存，重新插入USB转串口，普通用户就能搞定了

ros kinetic带的cv_bridge是基于opencv3.x的，在一些已有的工程项目中需要继续使用opencv2.X。当两个版本opencv共存时，即使修改/opt/ros/kinetic/share/cv_bridge/cmake中的cv_bridgeConfig.cmake，可以成功编译，在程序运行到cv_bridge的一些函数时依然存在错误。因为cv_bridge依赖d库是在open...
