The article analyses requirements of new methods of student education at the level of secondary school with professional electrical and electronic focus. It describes the creation of a new teaching aid that incites fantasy, concentration and motivation to create interesting things by self competence of students oriented to the electrical field of study. At the same time it orientates students towards unconventional ways of thinking and non orthodox solutions. Teaching aid exploits digital form that is attractive for young people with the aspiration to focus the attention of students to study professional knowledge.

In the current technological environment, operation of every institution, museum included, requires the use of IT networks, among them the internet. This results from the fact that museums have their respective websites and web addresses. Regardless of the technological aspects, the use of the internet by museums has to bear in mind legal requirements resulting in particular from the Act on Access to Public Information, this including the BIP page, namely that of the Bulletin of Public Information that allows to provide access to this kind of information within the range as defined in the above Act. The requirements of the accessibility of digital websites of public museums taking into account the needs of disabled citizens is specified by the Act on Accessibility of the Websites and Mobile Applications of Public Sector Bodies. Some of the provisions of the Act with respect to websites published before 23 September 2018 will come into force as of 23 September 2020. In the discussed context it also legal provisions related to IT assets that are of importance; these contain computer software and electronic databases. The legal status of these assets is specified in the provisions of the Act on Copyright and Related Rights (see its Arts. 3 and 7) as well as of the Act on Database Protection. Apart from the above, which, however, do not exhaust the whole range of the topic-related issues, it is also important to tackle the question of the digitizing of the assets (collections) that museums have at their disposal, in particular museum objects and images of people that constitute personal rights, which are digitized and disseminated online. Apart from the Act on Museums, particularly its Art. 25a, it is the Act on Copyright and Related Rights as well as the Civil Code that through the general provisions on the protection of personal rights, these also including images of people, give the prescriptive context to the problem.

A thermo-hygrograph is a chart recorder that measures and records both temperature and humidity in an analogue form. Converting the results into digital form is necessary to enhance evaluation of measurements archived on paper charts. Coordinate system of the charts is different than common Cartesian rectangular axis. Temperature and relative humidity axis are curved according to recorder pen holder ray. Different chart types, depending on particular thermohygrograph model, were used so far. In every case, however, the axis grid depicted in the background is geometrically precisely defined. So pattern recognition techniques could be used to find its location automatically. Temperature and relative humidity patterns can be retrieved automatically assuming that the color group of plotted lines is different than the background including the grid. Due to storing conditions, manual descriptions, discoloration and other factors, the plotted pattern cannot be unambiguously identified. Many randomly scattered pixels are interpreter as being part of a plotted line. Among additional measures, like excluding particular areas from analysis, manually removing and including points, a vector analysis of retrieved courses makes digitizing more effective.

Rozwój techniki pozwala dzisiaj na zastosowanie w procesie inżynierii odwrotnej wielu różnych urządzeń i metod do dyskretyzacji geometrii różnych obiektów. Każde z urządzeń jak i metod obarczone są pewnymi błędami, dlatego też, aby mówić o dokładnościowym aspekcie odtworzenia elementu w procesie inżynierii odwrotnej należy dokładnie zbadać i rozpoznać niedokładności, z jakimi mamy do czynienia w poszczególnych jej etapach. Dzisiaj ze względu na powszechne zastosowanie w przemyśle współrzędnościowych maszyn pomiarowych wykorzystuje się je do dyskretyzacji geometrii obiektów. W artykule opisano badania nad dokładnością odtworzenia powierzchni swobodnej w procesie inżynierii odwrotnej w zależności od liczby punktów pomiarowych otrzymanych w wyniku dyskretyzacji powierzchni swobodnej na współrzędnościowej maszynie pomiarowej.

Nowadays, the technical progress enables to use in the reverse engineering process a wide range of methods and devices for discretization of various objects. Every method and device, however, is subjected to a certain error. Hence, the accuracy of object reproduction is affected by the accuracy of each stage of Reverse Engineering process. At present, Coordinate Measuring Machines (CMM) are widely applied in industry, and they are often used for discretization of objects geometry for RE. In the paper, the accuracy analysis of the free surface reproduction in reverse engineering process, and its dependence on the number of measuring points has been discussed.

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.

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.

The Zofia and Jan Włodek Foundation in Cracow takes care e.g., of the photographic legacy of its patron Prof. Jan Zdzisław Włodek. Its most valuable element is a collections of 240 coloured positives on Autochrome plates manufactured by Lumière and Agfa- -Farbenplatten; it is one of the largest sets of photographs of this type taken by a single author which has been preserved in Poland. In 2020–2021, thanks to the financing from the Ministry of Culture and National Heritage, the collection underwent conservation and was digitized, following which it was made available to broad groups of viewers on the www.szukajwarchiwach.pl and www. zbioryspoleczne.pl portals. The unique photo technology used for their production constituted a real challenge in the set’s conservation and digitizing; moreover, attempts were made at an experimental digitizing of the selected autochromes with the use of directed bright-field. In order to promote the knowledge of the set, its author, and the works he conducted, videos and exhibitions were prepared, The whole project was quite challenging to a relatively small NGO. The key to its success was the cooperation of experts who proved to be flexible and creative in their approach to this particular task and peculiar conditions in which the project was implemented.
