This　article　presents　a　new　robust　LiDAR　processing　method.　This　method　fits　a　regression　plane　to　a　point　cloud　in　any　horizontal　position　by　fitting　a　disc　(with　R　radius)　on　it,　which　contains　a　specified　portion　(q)　of　points　under　the　disc　plane　in　all　three　sectors　of　the　disc.　This　method　can　be　used　to　create　digital　elevation　models　even　without　any　filtering　process.　This　article　also　describes　an　analysis,　which　compares　the　results　of　the　fitting　disc　method　using　different　parameters　in　processing　of　digital　elevation　models.　©　2017,　Budapest　Tech　Polytechnical　Institution.　All　rights　reserved.
