The development of modern surveying methods, particularly, Terrestrial Laser Scanning (TLS), has found wide application in protecting and monitoring engineering and objects and sites of cultural heritage. For this reason, it is crucial that several factors affecting the correctness of point cloud registration are considered, including the correctness of the distribution of control points (both signalised and natural), the quality of the process, and robustness analysis. The aim of this article is to evaluate the quality and correctness of TLS registration based on point clouds converted to raster form (in spherical mapping) and hand-crafted detectors. The expanded Structure-from-Motion (SfM) was used to detect the tie points for TLS registration and reliability assessment. The results demonstrated that affine detectors are useful in detecting a high number of key points (increased for point detectors by 8-12 times and for blob detectors by about 10-24 times), improving the quality and TLS registration completeness. For the registration accuracy of point cloud on signalised check points, the lower values can be noted for maximum RMSE errors for blob affine detectors than detectors and larger values for corner detectors and affine detectors (not more than 4 mm in the extreme cases, typically 2 mm). The commonly-applied target-based registration method yields similar results (differences do not exceed - in extreme cases - 3.5 mm, typically less than 2 mm), proving that using affine detectors in the TLS registration process is and reasonable and can be recommended.
Celem artykułu jest zwrócenie uwagi na relację pomiędzy trendami wzorniczymi lat 60-tych, na przykładzie filmu polskiego, a współczesnymi trendami we wzornictwie i projektowaniu mebla. Odwołanie się do filmów z okresu lat 60-tych, jako jednego z istotnych źródeł wiedzy o wnętrzach tamtego okresu, ma stanowić pretekst do dyskusji na temat ponadczasowości ówczesnych projektów. W szczególności, uwzględniając kontekst polityczny i okres PRL. Jednocześnie celem jest pokazanie, w jaki sposób wykorzystywać można źródła filmowe w innych dziedzinach nauki, w ramach badań interdyscyplinarnych, poprzez analizę obrazu filmowego dokonaną przez architekta. Film fabularny jest w więc istotnym uzupełniającym inne, źródłem wiedzy o formach i wnętrzach architektonicznych.

The aim of the article is to draw attention to the relationship between the 1960’s design trends, based on the example of the Polish film, and contemporary trends in furniture design. The reference to films of the 1960s as one of the crucial sources of knowledge about the interiors of that period is to be a pretext for further discussion on the timelessness of the 1960s designs, taking into consideration the particular political context in the Polish People’s Republic. The article, moreover, aims to show how film sources, analysed by architects, can be used in other disciplines of science, within the framework of interdisciplinary research. Summing up, the feature film is an important supplementary source of knowledge about architectural forms and interiors
