LIDAR Žemės paviršiaus taškų masyvo supaprastinimo algoritmų parametrų parinkimas

Abstract

The paper treats experiment of LIDAR points filtering. The goal of filtering is to remove redundancy points for map sheets printing and designing tasks. General aim is the precision of filtering data for designing tasks. Result of experiment is the chosen parameters of filters. Functions of smoothing, thinning, preservation of important points and combination of these functions were applied in analysis process. To compare results collected from different parameters of functions, the method of digging capacity was used. The values of parameters, that fulfill conditions, the calculation precision of digging capacity using in practice were defined.
