The applicability of alternative point-targets for laserscanning of underground and surface formations

Abstract

In this paper a research of finding the best point type, replaces the professional Leica HDS, without losing accuracy, and enables automating possibilities of measurement and processing process, during terran and and subterranean laser scanning of natural formations like rock outcrops and caves will be presented. The research started 3 years ago with many possible target-candidate and by the time the list narrowed to the two best in practise options and proven to be almost as accurate as the professional targets but for fractions of costs.
