Global digitization affects all sectors, including construction. Indeed, 3D scanning and digital photogrammetry methods are increasingly being used to obtain 3D data of buildings. The data obtained by these methods are a cloud of points, and our research is focused on this cloud's density. From the literature and our own previous research, it is known that different materials have different properties that are manifested in the structured-light 3D scanning of the surface of the measured object. We have selected materials with the assumption that their properties would negatively affect the density of the point cloud. The article describes the methodology of how the measurement of selected materials was performed and suggests material surface treatment possibilities to improve the properties of the materials for structured-light 3D data acquisition. The influence of suggested surface treatments on objects and/or materials was not investigated. Each intended case of using the suggested surface treatments needs to be considered individually to avoid object deterioration and/or material deterioration. Thanks to this research, it is possible to estimate the problem areas in terms of the materials during the reconnaissance of the measured object. The results of our experiments show that the treatments used can improve the accuracy of the measured object model and reduce the need to manually complete the model or scan the measured object several times.

The Lecturers Reference Guide for BIM (Building Information Modeling) is a specialized manual intended for educators in Higher Education Institutions (HEI) who are involved in Architecture, Engineering, and Construction (AEC) courses. The primary goal of this guide is to enhance lecturers’ level of competence in integrating BIM methodology into their teaching in a manner that is both collaborative and integrated. In essence, this guide serves as a comprehensive resource for lecturers, providing them with the tools and knowledge needed to effectively teach BIM in a way that aligns with the collaborative and integrated nature of this modern methodology in the AEC industry.

The aim of the paper is to bring new knowledge from ongoing specific university research. As part of this project, optical data collect locally and historically significant states of the chapel in Horní Nivy were collected using aerial and ground digital photogrammetry. The obtained data are subsequently analyzed for the needs of creating a virtual model. Data are generated from individual photographs as a point cloud. With regard to the parameters of the object, the data are captured partly from the ground using a camera and partly from the air using a camera mounted on a drone. By combining the exterior and interior model and removing unwanted points (noise), a model - a digital twin building - ai develop. The created model serves as a basis for the processing of construction technical and construction historical research.

This paper presents an application of photogrammetric methods for so-called image based modelling and rendering. Digital photogrammetry technology was used for the real use of a digital model of an artificial riverbed for a wild river in Tokyo. This technology was applied using two software programs, where we evaluate their compatibility and propose measures that should increase efficiency in the future in the creation of digital models of existing buildings. We describe the process of creating a model in both software separately and evaluate their use for a given type of object. In this paper, we describe the individual processes from the selection of photographs through the cleaning and smoothing of the point cloud to the final model. We present the practical use of the created digital model. In the pictures we show the solved structure, the process of joining individual photographs and the final model for the overall idea of the application of this method. The results and discussions section describes the evaluation of both software and proposals for measures for their use, especially for water structures of a linear nature containing recurring elements such as water barriers.

The aim of the paper is to describe the methodology of creating a digital model of human using an optical 3D scanner. This methodology consists of several main phases, such as preparing the scan for human movement, scanning in the shortest possible time, and processing the data obtained by scanning. The data processing itself is divided into other sub-phases, which describe the individual steps necessary to create a digital model. The paper describes obstacles thatneed to be eliminated or minimized during 3D scanning in order not to disrupt the integrity of the model and to create a digital model.

Nowadays, we use many of the modern technologies to make the optimal design of new buildings. Building Information Modeling Technology offers state-of-the-art solutions that allow the design of a building to create in many variants a realistically time-consuming development process and, by virtue of an almost fully automatic assessment of the variants, choose the most appropriate one according to the required criteria. Such a design of the building assumes its optimal behavior according to the criteria required by the investor, the user and other stakeholders, but also helps to keep the construction towards the sustainable development goals. There are many existing buildings that have obsolete properties. The management and durability of such buildings is very costly. Such buildings should be refurbished to meet the properties and imitations of new building behavior. 3D scanning technology goes hand in hand with the building sector digitization and outputs from 3D scanning technology serves as a useful basis for further working with data using BIM technology. This paper outlines the possibilities of creation of basics for current documentation with graphical information of these buildings and how it may serve for evaluation of possible options for repairs and reconstructions through the whole building lifecycle and further use in facility management.
