Opis:: The main goal of the work was an attempt to compare the free and commercial photogrammetry software for processing the pictures taken with a camera drone, a traditional digital camera and a smartphone. Due to a wide range of programs on the market, four were selected for comparison (Agisoft Metashape, DroneDeploy, VisualSfM, COLMAP). Their brief description was presented, and then the photos were processed in each of them. Three sets of photographs were used for the processing (part of a residential area, photos of a building, and photos of a tree trunk). As a result, the capabilities of the selected applications were presented on the basis of various input data. Not every program was able to deliver all the desired products. Moreover, they differ depending on the software. The commercial applications have more functionalities. On the other hand, the open-source solutions allow for the development of algorithms. Working in any environment had its own characteristics. The selected applications were compared on the basis of the processing and the results obtained. Due to many aspects of their evaluation, it turned out that the research topic was very extensive. Moreover, it was found that it is very difficult to make an objective statement of the tested programs, because the same program can be scored differently, depending on the user’s needs, capabilities and knowledge.

Opis:: This article evaluates the accuracy of 3D models made from point clouds obtained from photogrammetry. Photographs were taken from ground level and using a drone, and data processing was performed in 3DF Zephyr. The models were compared with the actual dimensions of the buildings. Four different building objects with varying degrees of complexity were analysed. The aim of the research is to analyse the conditions for taking photographs and how they are transformed into a point cloud, and to see how and whether the complexity of the shape of the facade affects the accuracy of the 3D model made from the point cloud. The inaccuracy of the point cloud in the form of point spread for all analysed cases was 1.8±0.4 cm on average. The largest measurement error was found in the case of a multi-storey building. Despite the presented inaccuracies, it was considered advantageous to use the point cloud obtained through photogrammetry in the inventory. No difference was observed in the accuracy of the model depending on the complexity of the building. Recommendations were made regarding the conditions for taking photographs.

Tytuł:: The use of Terrestrial Laser Scanning for the purposes of preparing technical documentation in BIM technology

Opis:: Building Information Modelling (BIM) is becoming an increasingly popular solution used both for investment and for reverse engineering aimed at restoring of the original documentation of existing facilities. The reconstruction of an object including its full design properties in an interactive 3D environment makes it possible to carry out structural (including SMH – structural health monitoring) and strength analyses, as well as to provide the effi cient facility management (setting out essential parameters and conducting necessary repairs). This paper aims to assess the laser scanning performed by using an advanced pulse data-capturing device for the development of complex BIM documentation in the Water Centre Laboratory of Warsaw University of Life Sciences – SGGW. Obtained point clouds have been used to build the model for the needs of reverse engineering. Moreover, the authors evaluated the possibility of using a particular type of laser scanner to develop and update complex BIM documentation in the process of facility management.

Opis:: Zieleń jest istotnym elementem współczesnego miasta. Chcąc zapewnić zrównoważony rozwój miastu należy zadbać o jej kondycję i odpowiedni udział w przestrzeni miasta. Dla efektywnego zarządzania zielenią niezbędna jest informacja o niej, w tym informacja o środowisku jej życia. Informację taką można uzyskać wykorzystując nowoczesne metody obrazowania i narzędzia GIS. Jednymi z ważniejszych źródeł informacji o zieleni stają się obecnie cyfrowe zdjęcia i chmury punktów z lotniczego i naziemnego skaningu laserowego. Usługi dotyczące zieleni opracowane w oparciu o takie dane zaprezentowane w układzie 2D i 3D dają pełną informację o stanie zieleni i jej potrzebach.
Greenery is an important element of a modern city. In order to ensure balanced development of the city, it is necessary to take care of its condition and proper participation in the city space. For the effective management of greenery, information about it, including information about its living environment, is necessary. Such information can be obtained using modern imaging methods and GIS tools. Digital photos and point clouds from aerial and terrestrial laser scanning are now becoming one of the most important sources of information about greenery. Greenery services developed on the basis of such data, presented in 2D and 3D, provide full information about the state of greenery and its needs.
