WebApr 12, 2024 · The IMU preintegration should start from the state of last lidar scan. However, the state of lidar named "g_lio_state" is also updated in r3live_vio.cpp. So the initial state in the function ImuProcess::lic_point_cloud_undistort is the state of the closest image frame, not the state of last lidar scan.
