Abstract

In this paper, we introduce an interactive application for planar curve design in a real world based on spatial augmented reality (SAR). The key component is a projector-camera unit that recognizes physical control objects (i.e., key points of an intended curve) using a camera and displays a design result (i.e., a B-spline curve) directly on the real world surface using a projector. Usually, geometric design is performed with the aid of CAD software and traditional user interfaces of a computer system. The main contribution of this paper is application of spatial augmented reality techniques in the domain of computer-aided geometric design (CAGD) for more tangible and intuitive interaction in a real world. We describe the feature of the prototype system and demonstrate the working application with examples.
基于空间增强现实的平面曲线交互设计
本文介绍了一种基于空间增强现实(SAR)的平面曲线设计交互式应用。关键组件是一个投影仪-摄像机单元,它使用摄像机识别物理控制对象(即预期曲线的关键点),并使用投影仪直接在现实世界的表面上显示设计结果(即b样条曲线)。通常,几何设计是借助CAD软件和计算机系统的传统用户界面来完成的。本文的主要贡献是将空间增强现实技术应用于计算机辅助几何设计(CAGD)领域,以便在现实世界中实现更加有形和直观的交互。描述了原型系统的特点,并用实例说明了其工作应用。
