ubuntu18.04 & ros melodic安装camera_calibration失败

参考ros官网上的双目相机标定教程camera_calibration/Tutorials/StereoCalibration - ROS Wiki，在使用以下安装命令时报错：

rosdep install camera_calibration

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
camera_calibration: Cannot locate rosdep definition for [sensor_msgs]

解决办法：

rosdep update  --include-eol-distros

然后再次进行安装即可。

原因：使用的ubuntu和ros的版本太老，必须明确地要求rosdep在运行rosdep update时—include-eol-distros。
