driver for complementary filter for a imu

serial: read serial hex from the unart port linked by usb cable to the imu module

yesense_driver_node: contains the node that publish imu message, euler message and do check sum from the serial read

six_axis_comp_filter: do comp_filter from the linear accel and the angular velocity

rostopic list:

/imu/euler_raw 原生输出的欧拉角 格式使用VectorStamped

/imu/euler_comp_filter 通过linear accel 和 angular elocity 进行互补滤波后的欧拉角数据 格式使用VectorStamped

/imu/data_raw 原生输出的imu 信息, 包括四元数, 线性加速度, 角速度

roll pitch -> 互补滤波

yaww -> 角加速度直接积分

使用欧拉角的情况下会有一个角无法进行互补滤波

shell脚本用于将rostopic 数据存入csv中, 如果写在一个脚本里, 两个rostopic好像没办法同时存两个数据,第一个读取结束, ctrl+c之后 进行第二个rosptic的读取, 故写在两个脚本里,分别运行

topic_ccf2csv.sh topic_raw2csv.sh
