Some questions about timestamp in odom.cc #25

Closed LetusRoll closed 11 months ago

LetusRoll commented 11 months ago

Hi,thank you for publishing a so good lio framework! I have some questions about the timestamp in function integrateImu().I think the start_time means the first point's timestamp, but you use prev_scan_stamp (the medium timestamp of last scan) in function deskewPointcloud(). Could you please explain?
