Protection of cultural heritage in recent times is of a very important significance. The priority task is to secure the existing facilities in such a way that they can now and in the future serve as a representations of the areas and be a treasure house of knowledge for both current and future generations. Through the development of new technologies and applying them by maintenance staff and those working to protect the national heritage, digitization has become widespread. Photogrammetry and laser scanning proved to be useful tools in a non-invasive process of heritage digitizing. In the article the author describes the process of creating a three-dimensional model of an architectural detail, the model of "acanthus leaf " which is the final product of the study. The methodology described by the author outlines the problems occurring during the measurement and subsequent data processing stages. The final product is an important database, useful when creating the reconstruction and renovation of similar facilities.Keywords: cloud points, digitizing, 3D model, relic, reconstruction, laser scanning, virtual cave Streszczenie Ochrona dziedzictwa kulturowego w aktualnych czasach ma bardzo ważne znaczenie. Priorytetowym jej zadaniem jest zabezpieczenie istniejących obiektów w taki sposób, aby mogły one teraz i w przyszłości pełnić funkcję reprezentacyjną danych obszarów oraz być skarbnicą wiedzy dla aktualnych i przyszłych pokoleń. Poprzez rozwój nowych technologii i zastosowanie ich przez konserwatorów oraz osoby zajmujące się ochroną dziedzictwa narodowego cyfryzacja stała się powszechna. Fotogrametria oraz skaning laserowy okazały się przydatnymi narzędziami w nieinwazyjnym procesie digitalizowania dziedzictwa narodowego. W artykule autor opisuje proces tworzenia trójwymiarowego modelu wybranego detalu architektonicznego, modelu "liścia akantu", który jest produktem finalnym badania. Metodologia opisana przez autora przedstawia problemy występujące podczas wykonywania pomiaru i w kolejnych etapach obróbki danych. Produkt finalny jest ważną bazą danych, przydatną podczas tworzenia rekonstrukcji i renowacji podobnych obiektów.
Occurrences associated with the phenomena of climate change are increasingly visible. Effects of progressive environmental pollution are monitored with growing concern. Still, in the construction sector, the choice of sustainable materials and the knowledge concerning them is insignificant. Studies have shown that single-family residential buildings form the largest share of new buildings in Central European countries. It should be assumed that it is the improvement of this particular section of the construction sector to be the goal of further development of societies. This paper presents a case study of the construction of a house using straw -a material that, on the one hand, is a product associated with local tradition, while significantly reducing carbon footprint of its production and use, on the other. The construction of a prototypical house with the application of composite technology, i.e. timber framing with straw bale infill, was compared with a conventional method (ceramic masonry units) which is currently the most popular choice for building single-family houses in Poland. The study is based on the building's life cycle assessment (LCA) over its consecutive phases as a tested and reliable method of the verification of a material's impact on the environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
