METHOD FOR DETERMINING DYNAMIC PARAMETERS OF MOVEMENT OF MATERIAL OBJECT DURING SPORTIVE MATCHES OR EXERCISING, APPARATUS AND METHOD FOR EVALUATING SPORTSMEN'S TECHNICAL AND CREATIVE POTENTIAL Russian patent published in 2005 - IPC

FIELD: sports, in particular, controlling methods and equipment.

SUBSTANCE: method involves registering paths of infrared traces created upon interaction of object with surrounding objects or environment; analyzing dynamics of changing intensity of infrared radiation in different parts of object's path and calculating parameters of movement of object on the basis of resulting values; registering path of infrared traces in various spectral ranges and path of shadowing resulted from interaction between object and concentrated or distributed infrared radiation sources; in high tennis cases, registering ball and tennis-court contacting region and moment when ball collides with tennis-court surface by breakdown of infrared radiation traces. Apparatus has infrared chamber, computer and mechanical vibration receiver connected with infrared chamber. Outside illumination source is frequency modulated type or infrared radiation wavelength modulated type and is synchronized with infrared chamber. Infrared chambers with adjustable image registering time, as well as rotatable and moving infrared chambers equipped with rotational or displacement drive may be employed. Infrared chambers may be provided with optical filter systems for changing their perception spectral ranges. Above methods and equipment allow all stages of sportive events to be registered and displayed to both referees and spectators, enable evaluation of sportsmen's skills to be effected more objectively and render help to engineering and scientific workers in improvement of sportive equipment.

EFFECT: wider range of use and increased efficiency.
