stract The article presents an analysis of the applicability of 3D laser model technology in the ergonomic assessment of the working environment. The results show that in the case of 3D technology, it is especially useful to describe the changes in the working environment and the ways of performing work activities (deviations from the regulations regarding activities specified by the employer). The article also presents algorithms for the use of 3D laser models in many workplaces where one cannot plan the work tasks in detail, since they are flexible and often their course is changed. This applies to work such as that of warehouse workers, maintenance staff or mining work. Keywords Ergonomic assessment engineering

1 Introduction Presently, there is an observable tendency towards computer visualization of an increasing number of aspects of the working environment, relating to not only the spatial parameters of the environment and its facilities, but also the real time visualization of the course of the whole production process including the body position of the worker during subsequent stages of production. The digitalization of various areas of a company, or the creation of a comprehensive network of digital models, methods and tools, which form a cohesive system, gives the opportunity to M.

manage data in a comprehensive way, however, it requires the collection of massive amounts of data, such as spatial parameters, as well as programming methods enabling pattern recognition. Given the growing demand for rapid recognition of hazardous states and the simultaneous documentation of these events for their later or remote analysis, 3D recording has become an indispensable tool in process excellence, which has a kind of side effect of increasing the ergonomic quality of work [1]. The use of 3D imaging methods can be found in the following areas of human activity: security features involving the identification of unique individual characteristics [2, 3], rendering body shapes for medical and rehabilitation purposes [4], reverse engineering [5], surveying, architecture [6], archeology [7], and for the purposes of forensic science, agriculture and forestry [8]. However, its relative applicability in ergonomic engineering to date has been limited to anthropometric measurements [9, 10] and the field of reverse engineering. On the other hand, there has been much development in the simulation capabilities of 3D technology [11], which allows to pres
