【摘要】：针对计算机动画的应用需求,引入生物学领域的先验知识,提出一种异步式的步态时序模型,并在此基础上实现一种足迹约束生成方法.首先对生物学领域内的经验知识进行建模,建立异步式的步态时序模型,以对四足动物的任意步态模式进行参数化的描述;然后通过设定速度参数,依据步态模型筛选出合适的步态模式,并在不同步态间进行过渡处理,生成四足动物完整运动序列的步态图;最后以步态图和速度为基础,面向地形、转向多种环境约束生成四足动物的足尖轨迹.实验结果证明,在生物学数据的支撑下,该方法仅需设置速度参数与环境约束便能够快速、有效地生成四足动物的足尖轨迹,将此轨迹应用于运动生成方法,可以求解出具有真实约束驱动的运动结果.
[Abstract]:According to the application requirement of computer animation, a new asynchronous gait time series model is proposed by introducing a priori knowledge of biological field, and a footprint constraint generation method is implemented based on this model. First of all, the empirical knowledge in the field of biology is modeled, and an asynchronous gait time series model is established to parameterize any gait pattern of quadruped animals. According to the gait model, the suitable gait pattern is selected, and the gait pattern is processed between different gaits to generate the gait map of the complete motion sequence of quadruped animals. Finally, based on the gait map and the velocity, the gait pattern is oriented to the terrain. Turn to a variety of environmental constraints to produce the tip track of a quadruped animal. The experimental results show that the method can quickly and effectively generate the tip trajectory of quadruped animals with only setting speed parameters and environmental constraints, and the trajectory is applied to motion generation method under the support of biological data. The motion results driven by real constraints can be solved.
