摘　　要：为构建更准确、更自然的三维人手交互系统,提出基于状态变量微观结构的粒子滤波算法和基于交互微观结构的反馈机制。对三维人手跟踪系统中的人手交互行为数据和人手状态变量数据进行分析,确定有效的交互微观结构和状态变量微观结构;利用交互微观结构建立有效路径选择及交互反馈机制;应用状态变量微观结构建立各个动作采样模型,构造采样数据库,完成基于状态变量微观结构的粒子滤波算法;采用基于状态变量微观结构的粒子滤波算法和基于交互微观结构的反馈机制构建三维人手交互系统,完成虚拟装配任务。实验结果表明:微观结构应用于三维人手交互系统,提高了算法的精度。To build a more accurate and more natural hand tracking system,we propose a particle filter(PF) algorithm based on the microstructure of state variable and an interactive feedback mode based on the microstructure of interaction.After analyzing the interactive behavior characteristics and the hand variable characteristics obtained from the three-dimensional(3D) natural hand tracking system,we identify the effective interaction microscopic structure and the effective microstructure of state variable.Interactive microstructure is used to establish an effective path selection and an interactive feedback mode.The microstructure of state variable is used to establish the hand action variable's sampling model and to construct the sampling database which is applied to PF.The PF based on the microstructure of state variable and the interactive feedback mode are used to build a 3D free hand interactive system and to finish virtual assembly task.Experimental results indicate that the microstructure applied in the 3D free hand interactive system improves the accuracy of the algorithm.
