基于kinect传感器进行手势控制X80机器
利用 kinect 传感器和 X80 移动机器人进行手势控制机器人移动的研究。
具体包括:(1) 基于 kinect 传感器的工作机制和设备的操作原理,设计了 5 种自然
交互的手势模板,包括前进、后退、向右转动、向左转动和停止。(2) 通过对比隐
马尔科夫模型算法和动态时间规整算法的优缺点,选出一种适合本文研究需求的
相对高效的算法——动态时间规整算法,并通过限制全局路径和失真度阈值进行
优化。利用优化后的动态时间规整算法验证上述 5 种手势识别的准确性。(3) 基于
PID 原理以及无线机器人软件开发工具包,依据手势识别的结果,解码器输出对应
的变量,从而控制无线机器人电机的运转。(4)利用 kinect 识别出的手势控制 X80
机器人的前后左右运动。

动态手势识别及应用研究
动态手势的识别部分,在特征提取阶段,将手心坐标作为手势的位置,并将
手心在空间中运动形成的一系列二维坐标点作为手势的轨迹,再把相邻的坐标点
间的方向角量化后得到的方向向量作为动态手势的特征向量。其中,对于轨迹开
始和结束的判断,则是使用了指尖的个数作为依据:当指尖个数为 5 时,轨迹开
始;当指尖个数为 0 时,轨迹结束。在识别阶段,则是利用了隐马尔科夫模型作
为分类器,实现了对于 10 种自定义的动态轨迹的训练和识别

Component-based distributed simulation system
As for model reuse,BOM technology has appeared as standard component.In this paper,BOM technology has
been used to construct a simulation application system which is originally HLA-based.Related problems with BOM are
also explored.BOM technology delivers that it is good for reuse and will be the key aspect in simulation development.

On a New Fault-tolerantElection Algorithm in the Distributed Algorithm s
Election algorithms arewidely used in the primary-backup replication, and ithas been proved to be harder than the con-
sensus problem. In this paper, the relation between the election problem and the consensus problem is analysed, and a new fault-
tolerant election algorithm is given. This algorithm is stable, communication-efficient, and itcan tolerate the temporal failure on the
processors and links. The algorithms proposed in this papernotonly solve the election problem, butalso provides a newway to solve
the consensus problem
