Terrestrial laser scanning (TLS) in carrying out projects in the con- struction industry is increasingly applied. This paper is considering the issue of ac- curacy that can be achieved by pulse TLS, evaluation of the measurement results and the applicability of this technology for the structure survey. Analyzing the measure- ment methods allows the identification of systematic errors of the instrument, which is serious obstacle for high-accuracy of TLS. In this article a standardization measu- rement procedure and the relationship between the projected tolerance and TLS cali- bration are given. At the same time the results of individual calibration of pulsed Le- ica scanners are presented, in which the systematic errors of measurement results are determined by the given model. Evaluation of survey results confirmed the high ap- plicability of TLS for the structures survey. Keywords: terrestrial laser scanners, structures survey, scanner calibration, survey results evaluation. 1. Introduction Terrestrial laser scanning provides a new approach to gathering information about the structures and allows the registration of thousands of different infor- mation per second. There are both: spatial as well as other types of information – the attributes of objects which are the subject of the scanning. The scanning pro- cess is almost completely automated, and the 3D information regarding the posi- tion of the scanned points are characterized by high precision. This allows consi- derable savings in terms of the amount of field work and the speed of the project Nedeljkoviæ Ostojiæ, J. i dr.: Analysis of Structure Surveying Method …, Geod. list 2011, 1, 37–54 37 1 Jasmina Nedeljkoviæ Ostojiæ, MSc, College of Professional Studies for Civil Engineering and Geodesy, Univer- sity of Belgrade, Hajduk Stanka 2, RS-11000 Belgrade, Serbia, e-mail: gjasmina@sezampro.rs, 2 Prof. dr.
