Аннотация. Изложены результаты исследования модели оптико-электронной системы измерения параметров движения в задачах биомеханики. Модель построена для определения точности измерения расстояния до точек объекта в процессе захвата движения для построения 3D-моделей. Данные, полученные с помощью модели, сравнивались с данными альтернативного метода. Полученные результаты находились на уровне существующих аналогов среднего класса при увеличенной в три раза дальности действия.

Summary. The article deals with the optical-and-electronic electronic system for measuring the parameters of motion (or motion capture) to create sports training programs. The purpose of a system is to use it to create 3D-models of movements of athletes during the competitions while the existing ones have limited range. An optical-and-electronic system for measuring motion parameters with a virtual pattern of structured backlighting is proposed. The use of such a pattern can increase the range of the system in 3 times. The virtual pattern exists only in the memory of the management computer. The principle of operation of the system proposed is based on changing the scale of the virtual pattern when changing the range to the object. The choice of the method of studying the feasibility of the proposed system is substantiated by the lack of technical resources and by initial state of the research. The conditions of the experiment to create a model are described, its stages are considered. The description of the equipment and programs used in the study is given. The equipment consists of a camera with a varifocal lens; computer with installed Matlab, a laser range finder, projector. The whole simulation process included simulation of the projection channel of the proposed system and simulation in combination with computer simulation of the receiving channel. Measurements for 10 different distances from 1.5 to 15 meters were simulated. During the process the measurements were also carried out by an alternative method. The simulation results showed that the accuracy of measuring the distance to the points of the object in order to create a 3D model of motion is at the level of existing middle class analogues, with a triple increased range.
