EVALUATION METHOD OF BIOMECHANICAL PARAMETERS OF SPORTSMEN MOVEMENTS

摘要

FIELD: sport.;SUBSTANCE: invention refers to the evaluation method of biomechanical parameters of sportsmen movements. In the date input block visual examination is performed and the required videofile with a picture of sportsmen and their physiological parameters is processed. In the block of determination of conversion coefficient coordinates the initial position of a sportsman at the start and finish shots is marked for further receipt of real coordinates points of a sportsman. In the block of automatic procession two shots from the videofile are consequently uploaded for each one, and for every such pair a black-and-white shot is seen for determination of the upper and lower limits of a sportsman at the shot by means of visual comparison of point brightness at the shot. By means of conversion coefficient real coordinates are determined and at the same time the position of the sportsman's centre of gravity is evaluated. In the interference filtration block possible interference during evalution of the position of sportsmen centre of gravity is eliminated. In the block of biochemical parameters calculation diagrams of velocity-time, acceleration, power, strength and power of sportsmen movements are obtained. Depiction, preparation of the printed report and recording of the obtained evaluation results is perfomed in the block of information output, printing and recording.;EFFECT: informativity increase of evaluation of sportsmen movement parameters.;2 cl, 4 dwg
