【摘要】：随着科学技术的快速发展,人机互动技术的应用越来越成熟,对其使用也越来越普遍。如今,实现互动的技术各式各样,人机互动不再仅仅只考虑精确的输入输出,更关注的是机器与人的高效自然互动。但是,目前的人机互动系统支持的互动点比较少,且互动面尺寸也比较小,基本只适合一到二个人的互动体验。同时,激光传感器电机运行时产生的干扰噪声对人机互动控制系统的影响很大。本文设计提出的基于激光传感器探测定位的人机互动系统解决了这些缺陷,对存在噪声的原始数据进行零距离值点滤波、动态自适应滤波等综合滤波,并设计了基于二维激光传感器的人机互动系统,突破了互动点较少及互动面尺寸较小的限制,可在大尺寸互动面上进行多人实时互动。其应用潜力巨大,可广泛应用于产品展览展示互动、博物馆显示互动和游戏娱乐互动等多个领域。本文设计提出的人机互动系统使用二维激光传感器作为核心硬件,并对其进行工作原理的介绍和误差分析,使用C#语言进行编程,实现硬件的控制、数据的传输通信、数据的处理等数个功能模块,并连接成一套控制软件。针对系统噪声提出了一个综合滤波算法,对存在噪声的原始数据进行零距离值点滤波和动态自适应滤波预处理,然后对预处理好的数据进行自适应阈值最近邻聚类滤波,并进行了常规加权滤波与综合滤波间的对比试验。经大量实验验证,该综合滤波算法可有效滤除噪声,提高互动点跟踪定位的精准度,并可实时运行,极大提升了互动体验效果。通过Ventuz三维编辑软件,设计编写互动显示内容并进行显示播放,用户即可在互动屏幕上进行主动式的互动体验。本文提出的人机互动系统已成功应用于张家港人民医院智能医疗中心,经过互动屏幕安装与人机互动系统调试,系统运行稳定,多人实时互动效果良好。项目的成功实施表明,本文设计提出的人机互动系统应用前景广泛,可实现大尺寸屏幕上的人机互动,且支持多个用户的实时互动,主动式的传播信息,使人机互动更高效自然,更加娱乐化、广告化和人性化。
[Abstract]:With the rapid development of science and technology, the application of human-computer interaction technology is becoming more and more mature, and its use is becoming more and more common. Nowadays, there are many kinds of technologies to realize interaction, and man-machine interaction is not only concerned with precise input and output, but also with the highly efficient natural interaction between machine and human. However, the current man-machine interaction system supports fewer interaction points, and the size of the interaction surface is also relatively small, which is only suitable for one or two people's interaction experience. At the same time, the interference noise produced by laser sensor motor has a great influence on man-machine interactive control system. In this paper, the human-computer interaction system based on laser sensor detection and positioning is designed to solve these problems. The original data with noise is filtered by zero-distance point filtering, dynamic adaptive filtering and so on. A human-computer interaction system based on 2-D laser sensor is designed, which breaks through the limitation of fewer interactive points and smaller size of interaction surface, and can be used for multi-person real-time interaction on large scale interactive surface. It has great application potential and can be widely used in many fields, such as product display interaction, museum display interaction and game entertainment interaction. The human-computer interaction system designed in this paper uses 2-D laser sensor as the core hardware, introduces the working principle and error analysis, uses C # language to program, realizes hardware control, data transmission and communication. Data processing and other several functional modules, and connected to a set of control software. In this paper, a comprehensive filtering algorithm for system noise is proposed. The original data with noise is preprocessed by zero-distance point filtering and dynamic adaptive filtering, and then the pre-processed data is filtered by adaptive threshold nearest neighbor clustering. The contrast test between conventional weighted filter and synthetic filter is carried out. A large number of experiments show that the integrated filtering algorithm can effectively filter noise, improve the accuracy of interactive point tracking and positioning, and can run in real time, greatly improving the interactive experience effect. Through the Ventuz 3D editing software, the interactive display content is designed and played, and the user can carry on the active interactive experience on the interactive screen. The human-computer interaction system proposed in this paper has been successfully applied to the intelligent medical center of Zhangjiagang people's Hospital. After the installation of the interactive screen and the debugging of the man-machine interactive system, the system is running stably and the effect of multi-person real-time interaction is good. The successful implementation of the project shows that the human-computer interaction system designed in this paper has a wide application prospect, can realize man-machine interaction on a large screen, and supports real-time interaction of multiple users and active dissemination of information. Make man-machine interaction more efficient and natural, more entertainment, advertising and humanization.
