Dissertations are not being sold



The doctorial work presents the research studies on the calibration methodology development for terrestrial laser scanners and the analysis on the implementation possibilities of laser scanners for modelling the Earth’s surface. The aim of the work is to develop the methodology for terrestrial laser scanner calibration without specified devices and instruments.

The results of the research performed are possible to be applied, when legitimizing the methodology of terrestrial laser scanner calibration. The attained results of the investigations could be used for improving the quality of the Earth’s surface modelling with the help of terrestrial laser scanner technology.

The introductory part justifies the analysed problem, determines the actuality of the problem, formulates the aim of the work as well as the tasks, presents the scientific novelty of the doctorial work, the defended propositions and mentions the author’s publications and reports made in various conferences, discusses the structure of the doctorial work.

The first chapter discusses the analysis of the related scientific literary sources. It presents the studies made on the structural peculiarities of terrestrial laser scanners and parameters of measuring systems. There are identified problems related to terrestrial laser scanner calibration and verification solutions made in Lithuania and foreign countries. Based on the analysed literature it has been determined that practically there has not been compiled any available methodology for calibration of terrestrial laser scanners without the available practical laboratory equipped with the required facility installations.

The second chapter of the doctorial work presents the compiled methodology dealing with the terrestrial laser scanner calibration, which has adapted the available methodology of the electronic distance meter calibration. It also presents the sequence of the performed experimental calibrations of terrestrial laser scanners.

The third chapter submits the ideas on the implementation of laser scanning technology for modelling the Earth’s surface. The chapter presents the analysis of the laser scanning technology application fields such as the mapping of the cultural heritage targets, or the correction of big errors in the accumulated data source for laser scanning technology, as well as the application of laser scanning data for modelling the open space surface.

Regarding the topicality of the doctorial work, there have been published 4 articles, six reports have been read in conferences.
