摘　　要：给出了一种跨越二维障碍物地形的虚拟人体下肢运动的生成方法。首先生成足迹,然后以足迹作为条件,基于简化的腿部模型,分别用不同的方法生成各部分的运动:用曲线拟合脚踝运动轨迹;采用增加约束条件的几何运算生成膝关节运动;采用曲线插值及升阶的方法拟合成脚踝跨越障碍物的运动。介绍了部分实现与实验结果。实验表明,该方法计算量相对较小,有一定的逼真性,适用于二维障碍物地形环境中人体下肢运动的生成。Present a method to generate movement of human legs on 2D terrain with barriers. First proposes a new method to generate footprints, and then take the footprints as condition, based on the simplified model of leg to generate different parts of movement by using different methods： synthetically curve presents the ankle trajectory; geometric operations with constraints is used to control knee motion; and the use of curve interpolation method to synthesize the ankle movement to across the barriers. Finally, introduces some of implementation and experimental results. Experiments show that this method has small calculation and high reality, apply to the movement of human legs on 2D terrain with barriers.
