| 摘 要： | 在计算机角色动画的抓取研究中，生成动作序列的自然性、稳定性及自适应能力三者难以同时
得到保证，即自然又稳定的抓取控制器往往泛化能力有限，无法适用于其他类型、尺寸物体的抓取任务。通过
引入和抓取类型相对应的手部示教数据、设计回报函数，构建了一种基于深度强化学习的虚拟手自适应抓取控
制器。实验结果表明，该控制器能够生成兼具自然性和稳定性的抓取运动序列，同时对素材库中不同尺寸、不
同类型的基元物体也具备较好的自适应能力。

| Abstract: | For the grasping of computer character animation, it is difficult to guarantee the naturalness, stability and
adaptability of the generated action sequence at the same time. In other words, the natural and stable grasping
controller are often limited in generalization and cannot be applied to other types of grabbing tasks. A virtual hand
adaptive grasping controller was constructed based on deep reinforcement learning by introducing hand teaching data
corresponding to the grasping types and by designing the reward function. Experimental results show that the designed
controller can generate a grasping motion sequence with both naturalness and stability, and are also highly adaptive
for different sizes and types of primitive objects in the material library. |
