摘要
人体运动的仿真在分布虚拟战场环境仿真、灾难救援训练、交互式防暴演习等领域有重要的应用。人体是由200多个关节组成的复杂形体,本文采用层次化、关节化的建模方式对人体进行建模,从实用角度,通过运动学方法得到各关节旋转角。根据研究对象的特点,采用基于多摄象机跟踪固定在人体上的标记点的光学测量方法,在此基础上实现人体空间测量数据到关节运动角度的转换,驱动三维高逼真度人体仿真模型。并应用于战场环境士兵仿真以及救援操作作业人员的仿真应用,取得良好的仿真效果。
The simulation of mans motion plays an important role in the areas of distributed virtual battlefield simulating, disaster rescuing and interactive riot policeman exercising. The clay is a complex body made of more than 200 articulations. The modeling method of hierarchy and articulating is used. Then the angles of articulations are obtained through kinematics method. Based on the features of researched object, the optic measure method in which the marker balls are tied up on the body and are captured by multi cameras is adopted. After that, the motion angles of articulations are calculated upon the spatial measured data, and are used to drive the three-dimension high-resolution body model. All of these are applied to soldier training in battlefield environment and rescuer simulation application, and get good effect
