Development of a System for Supporting Collaborative Design of Clothes in Virtual Space

本研究的目的是开发一种支持服装设计的环境，该环境以立体显示器为输出设备，三维定位设备为输入设备，在虚拟空间中直接操纵服装。1.基于虚拟对象操作的增强现实注册交互调整在增强现实环境中，为了使用包括用户手在内的真实对象来操作叠加到真实空间中的虚拟对象，需要实现注册，即调整真实空间和虚拟空间的位置和方向。在本研究中，我们实现了确定操作虚拟物体的配准误差可接受范围的过程，并通过用户通过虚拟物体操作交互地调整配准来实现自适应配准以同时达到可接受的范围。从真实观察中虚拟可变形物体的形状目的是从真实物体的观察中获得描述可变形物体在操纵下的三维形状的虚拟物体模型。为了实现这一目标的第一步，我们实现了估计模型参数的过程，该模型参数再现了摄像机在垂直平面上操纵的弦状真实物体的观察结果所获得的3D形状。基于虚拟空间直接操纵的服装设计系统的开发我们开发了一个通过在虚拟空间中直接操纵服装的三维形状来设计二维服装图案的系统。在我们的服装设计系统中，用户首先选择由典型图案组成的服装模型，然后在虚拟空间中通过操纵来修改其3D形状

The objective of this research is to develop an environment to support clothes design based on direct manipulation of clothes in virtual space by using a stereoscopic display as the output device and a three dimensional (3D) pointing device as the input device. The major results of this research are summarized as below :1. Interactive Adjustment of Registration for Augmented Reality though Virtual Object Manipulation In order to manipulate virtual objects superimposed into the real space using a real object including the user's hand in an environment with augmented reality, it is necessary to realize registration, which is to adjust the positions and orientations of the real space and the virtual space. In this research, we realized the process that determines the acceptable range of errors for the registration to manipulate virtual objects and realizes the adaptive registration to attain the acceptable range at the same time by adjusting the registration " interactively though virtual object manipulation by the user.2. Virtualizing Shapes of Deformable Objects under Manipulation from Real Observation It is aimed to obtain a virtual object model that describes 3D shapes of deformable objects under manipulation from observation of real objects. For the first step toward this goal, we realized the process to estimate the model parameters that reproduce the 3D shape obtained as the results of observation of string like real objects manipulated on a vertical plane by a camera.3. Development of Clothes Design System Based on Direct Manipulation in Virtual Space We developed a system to design 2D patterns of clothes by direct manipulation of the 3D shape of the clothes in virtual space. In our clothes design system, the user first selects a model of clothes constituted by typical patterns and modifies their 3D shape by manipulating them in virtual space
