Abstract

Terrestrial laser scanning (TLS) in carrying out projects in the construction industry is increasingly applied. This paper is considering the issue of accuracy that can be achieved by pulse TLS, evaluation of the measurement results and the applicability of this technology for the structure survey. Analyzing the measurement methods allows the identification of systematic errors of the instrument, which is serious obstacle for high-accuracy of TLS. In this article a standardization measurement procedure and the relationship between the projected tolerance and TLS calibration are given. At the same time the results of individual calibration of pulsed Leica scanners are presented, in which the systematic errors of measurement results are determined by the given model. Evaluation of survey results confirmed the high applicability of TLS for the structures survey.
