Sprinter joint point identification model of biomechanics

This article USES the automatic identification of human body joint point in the process of sports science algorithm, as a key point to discuss, in order to more realistic three-dimensional reconstruction basis of science. Through the body’s automatic identification of the key software implementation process research, and in this paper, the image processing model to reconstruct the human body model according to the proportion principle in the late. Using camera measurement instruments and scientific measurement method, provides effective scientific data collection. Research results, to determine the link of 15 and 21 key points of the body, and gives the mathematical model of each joint point determined to establish the discriminate model of special circumstances, are visible side joint point enter human body contour line, invisible side joint point of shade and hands on hip to determine the influence of processing method
