Is there original data of high frequency IMU?
IMU raw data has already be converted to pose of every sensor, you can find keyword "pose" of every sensor.
@xpchuan-95 Because I need IMU raw data to research about multi-sensor VINS system, if you can provide original imu data, I will be very grateful to you.
I am sorry that it's hard to get raw IMU data, but the pose of camera is directly calculated by IMU/GPS data, can you try to use pose of camera as IMU data?
The advantage of having raw IMU data is that it has a higher temporal resolution. This is useful for the motion-compensating the points from the spinning lidar. There, each point has its own timestamp, which means that it has to be treated separately when doing the motion compensation.
