摘要
积木是一种具有高度易用性的设计工具,通过简单而牢固的插接结构可以创造大量各式各样的实体模型,如建筑、机器和人物等.传统上,搭建出的实体模型可以通过计算机视觉的方法进行三维重建,但是识别率低、操作复杂、遮挡等问题始终无法得到妥善的解决.为此,提出了一种基于分布式传感的实时三维重建系统,系统包括硬件层、网络层、交互层和应用层4个层次;通过传感数据处理、结构重建模块及三维显示模块,实现实体积木的实时数字化重建与显示.这一系统基于连接单元间的拓扑关系检测,因此能够从原理上解决遮挡、识别等问题.基于该系统,通过原型开发及用户实验,探索了模块化实物用户界面在计算机辅助设计、教育及互动娱乐等领域的应用前景.
Building blocks is a kind of highly easy-to-use design toolkit,by which a wide variety of tangible models(buildings,machines,figures,etc.)can be created through simple and robust interlock structures.In traditional,the models built by tangible bricks can be reconstructed via computer vision method,but many problems still have not been solved properly,e.g.,low recognition rate,complicated user manipulation,and occlusion between bricks.This paper proposes a real-time 3 D reconstruction system utilizing distributed sensing technology.The system architecture is divided into four layers:hardware,network,interaction and application.Through the sensor data processing,structure reconstruction and 3 D display module,tangible models built by tangible bricks can be digitalized,reconstructed and displayed in real time.This system is based on topological detection between connected units,such that problems like occlusion and recognition can be solved in essence.Through the development of prototype and pilot user study,we explore the application prospect of modular tangible user interface in various fields,e.g.,computer aided design,education and entertainment.The system can be applied in various areas,e.g.,education,entertainment and design.
