The aim of this work is to investigate the process of obtaining necessary information about the metric parameters of small-area arrays, linearly arranged and individual green plantings on predominantly urbanized territories, and to apply the results of data processing in the compilation of topographic and special maps from the corresponding scanning materials. Methodology.
terrestrial laser scanning
The aim of this work is to study the Turka quarry using terrestrial laser scanning, as well as to build a 3D model of the object. Method. The study of the outcrop was carried out with terrestrial laser scanning. The article describes the principles of operation of laser sensors and provides a classification of error sources. It also emphasizes the importance of achieving the maximum accuracy specified by scanner manufacturers. The location of the researched object. The studied quarry is located on the northern outskirts of the city of Turka, Lviv region.
Calibration of terrestrial laser scanners allows increasing the accuracy of the obtained data in order to comply with regulatory requirements for engineering geodesy works. Two types of test objects (TCO) are used for calibration: point-based and plane-based. The aim of this work is to evaluate, summarize and classify the criteria for selecting the type and subtype of test objects for terrestrial laser scanners calibration.
Purpose. The purpose of this study is to determine the reliability of the results obtained using a fully automatic method for orienting scans. The results are determined in two different common software tools and compared with the results of scanning scans by combining common points using special marks - 3D spheres. Methodology. A technique is proposed based on the creation of several scanning stations at a short distance and one at a relatively larger distance. One of the distant from the scanned stations will be determined by the basic.
The analysis of modern technologies to create the frontal plans of architectural heritages using laser scanning and digital camera is presented in the paper
