IMU question : Average? #34

Closed Camilochiang closed 1 year ago

Camilochiang commented 1 year ago

Good day. Does anybody knows what the author is doing with the IMU data ? The original livox ros driver ouput either 0 or 200 HZ, meanwhile the supplied bags are sync to the same frecuency between IMU and LiDAR (and same timestamp). You can see it here for example

Thanks!

Hi, thanks for your interest. The IMU frequency in the bags tested by LIVO is about 200Hz. As for the visualization of rqt_bag, you should zoom in to see the IMU messages.
