In the dataset page, it said,
LIDAR:
2 x SICK LMS-151 2D LIDAR, 270° FoV, 50Hz, 50m range, 0.5° resolution
1 x SICK LD-MRS 3D LIDAR, 85° HFoV, 3.2° VFoV, 4 planes, 12.5Hz, 50m range, 0.125° resolution

when I run the build_point cloud script with same parameter using /lms_front and /ldmrs laser scan folder, I find 2D LIDAR data provide more information in vertical axis than 3D LIDAR, it looks like below, first pic is /lms_front result and second pic is /ldmrs result.

Hi, I got the same problem as you. Do you try it with Python or Matlab code?
