Abstract

The article is devoted to the issue of a formalized description of the components of the uncertainty of the virtual digital scale of the control system built on the basis of video recorders in order to present it as a means of measurement. The analysis of the structure of the system is carried out in order to determine the hardware and methodological components, uncertainty. The modes of calibration, certification, control, the issues of creating digital twins based on the kinematic portrait of a person for use in rehabilitation systems in medicine and sports are considered. The creation of digital twins of objects, systems, processes is widely used to improve the accuracy of monitoring their condition, forecasting, improving the quality and reliability of management decisions. At the same time, an important aspect is to reduce the uncertainty of the boundaries of patterns, which increases the reliability of the system application and the development of a control action or a prediction result. Uncertainty reduction is provided by means of measurement, with the help of which control procedures are carried out.
