How to use this program to calibrate mid360 parameters? about lidar_imu_init HOT 3 OPEN

Getting different results each time is normal, as any algorithm calibration comes with errors. If the differences in your results are not significant (such as a rotation of 1 degree or a translation of approximately 2 cm), you can use the average value by calibrating several times. However, if the differences are substantial, it is recommended to calibrate again..

What about the time stamp gap? Is the timestamp from each correction also averaged? I saw that the mid360 official website has its imu radar relative position information, so my key question is to get the time difference between them.

“Is the timestamp from each correction also averaged？” -- YES.
Under normal circumstances, the time lag between multiple calibrations of the mid360 and IMU should not vary significantly, usually smaller than 5ms if the parameters are tuned well.
