运行roslaunch imu_utils出错

使用imu_utils标定白噪声和偏置随机游走时,调用命令

roslaunch imu_utils mems.launch

出现

[mems.launch] is neither a launch file in package [imu_utils] nor is [imu_utils] a launch file name
The traceback for the exception was written to the log file

报错说明ros系统中,并没有安装相对应的package,在catkin_make前先运行下面这条指令

source devel/setup.bash

将devel/setup.bash添加到系统,之后再运行

catkin_make

再次执行roslaunch指令就可以了。
