Title:
AUTOMATIC ANALYTICAL METHOD FOR HUMAN KINETIC ENERGY
Document Type and Number:
Japanese Patent JPH0399637
Kind Code:
A
Abstract:
PURPOSE: To obtain all data required for biodynamic and physiological examinations by measuring respective energy for the position for parallel advancement, for rotational movement and for the total of each body part at each body position corresponding to a single piece of frame. CONSTITUTION: When a body 11 starts walking or running on a conveyor belt 12 and equipment 10 is in operation, television cameras 25 and 26 measure the light reflected by the signals 14-24 at a frequency of 50-100Hz over a specified period of time and transmits it to a processing unit 33. The processing unit 33 restructures a 3-dimensional arrangement of the signals 14-24 from the 2-dimensional measurement, measures the correspondence between the signals and respective each part of the body and obtains a dynamic model which roughly defines a body 11. Next, by utilizing Fourier analysis, a series of positions of the signal marks 14-24 which change with the time elapsed, are filtered, and with reference to the entire body mass as a center, the space coordinates, the speed of a parallel advancement, a movement energy, position energy and the total energy concerning each body position, corresponding to a single piece of frame are calculated.
