摘　　要：随着仿真和虚拟现实技术的发展,虚拟人技术由理论研究逐渐走向实际应用,在医学、军事、航天、体育、艺术等领域发挥越来越重要的作用。然而,由于人体外形和运动的复杂性,对人类自身完美地模拟还十分困难。以队列训练模拟器为背景,重点研究了系统中虚拟人的几何和运动控制建模。根据军事队列训练的目标和要求,采用分层虚拟人表示方法,建立了具有树形结构的人体几何模型;应用基于视频的运动捕捉技术和运动学方法,控制虚拟人的行为动作;以齐步走为例,给出了仿真结果。仿真和实验结果表明,所建立的人体几何模型逼真可信,基于视频的运动捕捉和运动学结合的运动控制方法有效、逼真地对虚拟人进行了控制。With the development of simulation and virtual reality technology,virtual human technology is applied gradually from theoretical research.It plays an important role in medical,military,aerospace,sports,arts and other fields.However,the shape and movement of human are complex,therefore,the perfect simulation of human is very difficult at present.Based on the simulator of formation training,the paper discussed how to build human body model and motion control model mainly.According to the goal of formation training,a virtual human body with tree-struture was built by suing multi-layer technique.The motion capture method based on video was proposed and kinematics technique was used to control the movement and behavior of virtual human,then the simulation results of quick march was given.Simulation and experiment results showed that the geometry model of human body was realistic and credible,and the motion capture based on video combined with kinematics control method could control the virtual human effectively and vividly.
