Is it work under low rate of lidar? #145

Closed bigbigpark closed 2 years ago

bigbigpark commented 2 years ago

I have a ouster-32ch lidar.
I logged all data[lidar, imu, gps] under 1 Hz.

When I run roslaunch fast_lio mapping_ouster64.launch, nothing worked on Rviz.
I have tested KITTI dataset (10Hz's Lidar), another dataset(maybe 20Hz's Lidar). I worked well

The 1 Hz is too low to run this fast-lio2 ?

Best regards.

I am trying to use this algorithm for Kitti Dataset. Can you tell me how did you apply FastLio with Kitti Dataset I am getting these errors Failed to find match for field 'intensity'. Failed to find match for field 'time'. Failed to find match for field 'ring'.
