摘要
针对当前虚拟人运动建模中缺少环境约束这一问题,文中提出了一种基于环境约束的逆向运动学求解方法。主要研究了在环境约束下,如何运用逆向运动学方法使人体的步行运动更加真实直观。首先提出了人体的层次结构模型和关节模型,其次对CCD算法的实现方法进行分析,最后结合CCD算法提出一种在环境约束下调整人体步行运动的方法。解决了运动捕捉方法中动作单一的问题,使虚拟人能够根据环境信息调整现有的动作,最终能够使虚拟人在平坦地面的运动和上下台阶运动都更加灵活真实。
To solve the problem of lack of environment constrains in model-building of virtual human,a solution method of IK that based on environment constrains was newly proposed.Mainly probed how to use inverse kinematics method to make the walking motion of virtual human more intuitionistic with environment constrains.Primarily,investigate the multi-layered model and joint model.And then,the procedure of CCD algorithm was analyzed.Finally,proposed an idea of adjusting human walking motion that based on environment constrains with CCD algorithm,so that the problem of motion singleness is solved.The motion of virtual human on even ground and stair could be more flexible.
