Purpose

This study aimed to clarify the criteria for subjective evaluation of the similarities and differences between virtual and actual pants and propose a quantitative evaluation method for those similarities and differences based on geometric features related to the evaluation.

Design/methodology/approach

Using patterns, we made five pairs of actual pants for a dummy in five fabrics. We simulated virtual pants with a 3-D simulator. Sensory evaluation was conducted with images of the virtual and actual pants: 20 participants compared the images based on a questionnaire. For the structure of evaluation, the authors undertook analysis of variance and principal component analysis. The actual and virtual pants were geometrically compared using the 3-D scanned data. To investigate the relationship between quantitative and sensory evaluation, the authors calculated the correlation coefficients.

Findings

The authors found that subjects perceived the differences between actual and simulated pants. When comparing the virtual and actual pants, the criteria for the differences were the silhouette from the front view, hem width, waist and wrinkles. Using differences in the hem width, it would be possible to evaluate the differences between actual and simulated pants. Roughness and smoothness of the silhouette also affected evaluation.

Originality/value

The authors clarified the evaluation criteria for the similarities and differences between virtual and actual pants. The authors proposed a quantitative evaluation method for the similarities and differences between virtual and actual garment based on our criteria. This study will be of benefit to 3-D simulator users and developers.

虚拟裤子与实际裤子之间的异同

目的

这项研究旨在阐明主观评估虚拟裤子与实际裤子之间相似性和差异性的标准，并基于与评估相关的几何特征，针对这些相似性和差异性提出定量评估方法。

设计/方法/方法

使用图案，我们用五种面料制作了五对假人的实际裤子。我们使用3-D模拟器模拟了虚拟裤子。使用虚拟裤子和实际裤子的图像进行了感官评估：20名参与者根据问卷调查对图像进行了比较。对于评估的结构，作者进行了方差分析和主成分分析。使用3D扫描数据对实际和虚拟裤子进行几何比较。为了研究定量评估与感官评估之间的关系，作者计算了相关系数。

发现

作者发现，受试者意识到实际裤子和模拟裤子之间的差异。比较虚拟裤子和实际裤子时，区别的标准是前视图的轮廓，下摆宽度，腰围和皱纹。使用下摆宽度的差异，可以评估实际裤子和模拟裤子之间的差异。轮廓的粗糙度和平滑度也会影响评估。

创意/价值

作者阐明了虚拟裤子与实际裤子之间异同的评估标准。作者根据我们的标准，提出了一种虚拟评估和实际评估之间的异同的定量评估方法。这项研究将对3-D模拟器用户和开发人员有所帮助。
