虚拟人体运动系统建模方法研究

Modeling Methods of Virtual Human Movement System

利用模型研究人体的运动原理和规律,是人体运动研究的一个重要手段和有效工具。本文主要介绍了几种常用的建模方法,其中包括弹簧-阻尼-质量力学模型、多刚体模型、神经-肌肉-骨骼系统模型、基于数字人体图像的模型和基于人工神经网络的模型等方法。并分析了各种方法的特点和适用范围以及建模中存在的难点和关键问题。

It is an important method and efficient tool that using a model to study the motion principles and laws of human movement. This paper presents several methods of modeling, which include the spring-damper-mass mechanics model, the multibody model, the neuro-musculo-skeletal system model, the model based on digital image of human body, the model based on ANN and so on. Moreover, we analyze features and application ranges of every method as well as difficulty and key problem of modeling.
