ABSTRACT:For the preparation of modern specialists in the acquisition and processing of three-dimensional data, a broad and detailed study of related modern methods and technologies is necessary. One of the most progressive and effective methods of acquisition and analyzing spatial data is terrestrial laser scanning. The study of methods and technologies for terrestrial laser scanning is of great importance not only for GIS specialists, but also for surveying engineers who make decisions in traditional engineering tasks (monitoring, executive surveys, etc.). The understanding and formation of the right approach in preparing new professionals need to develop a modern and variable educational program. This educational program must provide effective practical and laboratory work and the student's coursework. The resulting knowledge of the study should form the basis for practical or research of young engineers. In 2014, the Institute of Applied Sciences (Jade University Oldenburg, Germany) and Kyiv National University of Construction and Architecture (Kiev, Ukraine) had launched a joint educational project for the introduction of terrestrial laser scanning technology for collection and processing of spatial data. As a result of this project practical recommendations have been developed for the organization of educational processes in the use of terrestrial laser scanning. An advanced project-oriented educational program was developed which is presented in this paper. In order to demonstrate the effectiveness of the program a 3D model of the big and complex main campus of Kyiv National University of Construction and Architecture has been generated.

Culture heritage will always remain one of the priorities of any state. Taking a cultural or historical object under protection is impossible without inventory. The best technology, which allows getting high-quality inventory, is close-range photogrammetry. Unfortunately, the full capabilities of this technology is fully owned by professionals only. The situation changed significantly with the advent of mobile devices that are equipped with digital cameras and low-cost software that does not require any special knowledge in the theory and practice of photogrammetry. These developments have been called lowcost photogrammetry technologies. In the present study, we examined the use of smartphones and nano UAV and PhotoScan software for solve the problem fortifications II World War inventory near the city of Kiev. For qualitative data, the calibration of digital cameras in smartphones and ultra-light UAV was performed on calibration bench. One of the features of this project was the integration of the terrestrial photos and photos captured by nano UAVs. As a result of work performed were obtained 3D models of fortifications. Results showed high efficiency of the low-cost photogrammetry technologies. At the end of work some practical guidelines were provided, how to get high-quality data using low-cost photogrammetry technologies.
Abstract. We are presenting a concept and first results of a Terrestrial Laser Scanner simulator - a tool, which could be a valuable educational tool for geomatics and engineering students. The main goal of the VirScan3D project is to cover engineering digitisation by two major project parts: 1) Development of a virtual environment for creation and processing of digital 3D scan data; 2) Digital teaching and e-learning material with interactive tools and practical experiences. Part 1 will be solved through the development of a virtual system that allows users to create realistic data in the absence of a real measuring device. At the time of writing (April 2020) all higher education teaching and learning worldwide has been changed to online delivery due to the Covid pandemic. However, this has affected the courses that involve working with equipment and – consequently – require the presence of students and devices. In this project, the development of such equipment simulator proposes a real and feasible solution, which allows undisturbed continuing the teaching.The virtual scanner will be based on existing software packages. It will be part of a general e-learning concept that will be implemented in partner universities. Part 2 is addressed through an integrated teaching concept that includes interactive learning tools (for both teachers and students) and practical exercises (for example project weeks, summer schools) where the theoretical and virtual education is connected to practical experience with real instrumentation and data. One outcome of the experimental work is additional e-learning material based on the experiences and results of the project work.The prototype implementation of the virtual laser scanner is realized within a game engine, which allows for fast and easy 3D visualisation and navigation. Within this environment, the user can freely navigate and define suitable scanning positions/stations. At each scanning station a simulated scan is performed, which is based on the technical specifications of a real scanner. The mathematical solution is based on 3D line intersection with the virtual 3D surface including noise and colour as well as an intensity simulation. As a result, 3D point clouds for each station are generated, which will be further processed for registration and modelling using standard software packages.
Abstract. Within the project VRscan3D, funded by DAAD, a terrestrial laser scanner simulator has been developed as educational tool for learning and teaching laser scanning processes. The main goal of the VirScan3D project is to cover engineering digitisation and will be solved through the development of a virtual system that allows users to create realistic data in the absence of a real measuring device in a modelled real-life environment (digital twin). The implementation of the virtual laser scanner is realised within a game engine, which allows for fast and easy 3D visualisation and navigation. Real-life buildings and urban surroundings can be digitised, modelled and integrated into the simulator, thus creating a digital copy of a real-world environment. This article describes the technical realization of the simulator and its evaluation as well as usability testing results conducted by independent users from university courses.
As a result of this research, a methodical approach to the geoinformational analysis of the waste containers’ placement for the collection of municipal solid waste in urban areas according to current standards and rules for the improvement of settlements was developed. According to the current Rules of maintenance of residential buildings and adjacent territories, waste containers of all types should be installed on a concrete or asphalted site, usually with fencing made of standard reinforced concrete products or other materials with planted shrubs around the site. Moreover, container platforms on wheels should be equipped with a ramp from the roadway and a fence (curb) which is 7–10 cm high, to keep the containers from rolling off to the sides. In the process of determining the optimal locations of waste containers a database of container park was created including the register of containers, the register of platforms, and the register of trash cans was created a list of influencing factors at the data collection stage, was made a proximity analysis and data reclassification to move to a unified scale for calculations of different types and/or heterogeneous source data, and weighted overlay as the main instrument of aggregated analysis. The analysis of the results is based on comparing the location of existing waste container sites with the resulting overlapping areas.
Recently, virtual reality technologies are increasingly being introduced into our lives. The focus of their use is shifting from the entertainment industry to design, healthcare, tourism, architecture, education and more. The advantages of virtual reality technology are especially noticeable in the field of archaeology, as many historical objects have not survived to our time, and their appearance can be reproduced only on the basis of historical sources and archaeological excavations. Most platforms for implementing virtual reality programs are based on game engines that can provide the required level of performance for VR. Such platforms show very good results for architectural objects, which often have many similar elements of simple shapes. Integrating complex objects with unique shapes is usually a problem. In this article, we consider the use of photogrammetric methods to create 3D models of historical objects and the aspects of their integration into a virtual environment based on a game engine. Specifically, aspects such as object resolution and suitable level of detail are discussed. As a case study, such a virtual environment was created for the ancient Trypillia settlement in the territory of Ukraine.
