虚拟人的步行和跑步运动控制方法的研究

摘要

Two basic locomotion models of walking and running f or virtual humans and their control methods is studied. To insure that the behav ior of virt ual human conforms to the motion rule and characteristics of humans, the body ge ometrical and kinematics models are given firstly. Then a control technology, wh ich combines the keyframing, forward kinematics, inverse kinematics and simple d ynamics methods, is presented to generate the periodical walking and running. To make walking and running actions with different velocity, frequency and step le ngth, we introduce the motion characteristic parameters.%研究了虚拟人的步行和跑步两种基本运动模型及其运动控制方法。 首先提出了人体的几何模型和运动学模型，其次 对人体行走和跑步模型进行分析后，提出了用关键帧，正向、逆向运动学和简单动力学适当 结合的控制方法，实现了周期的步行、跑步等移动动作，并引入运动特征参量来控制步行和 跑步速度、频率及步幅特征。
