Methods for analyzing biomechanics using video and personal computers

摘要

Abstract: Previously, the mechanical analysis of biological systems has been a costly and labor intensive operation. Now, the noninvasiveness of video, combined with the inexpensive power of the personal computer, has led to a revolution in quantifying movement. Methods used to acquire kinematic and kinetic data include two-dimensional (2-D) and three-dimensional (3-D) manual and automatic point tracking, analog acquisition, and a variety of processing procedures. !2
