【摘要】 从民用设施和军用装备的设计和评价需求出发,提出一种以大样本人体尺寸数据和大样本人体三维点云数据为基础,综合参数标准差和相关性分析结果,采用参数回归技术构建三维工效虚拟人的建模方法。该方法对于人体各部位或者整体的分号型建模具有普适性,可在号型较少的条件下,提高虚拟人模型的总体覆盖率,使其所得到的三维虚拟模型有较好的代表性,而且回归技术建立的工效虚拟人在外部形态上细节丰富,真实性强。以该方法为基础,采用Qt为主要框架开发了一个用户可交互的建模平台,在该建模平台上,以服装用工效虚拟人需求为例,选用服装设计常用的12个参数,构建了服装工效虚拟人系列,包括13个标准体号型,覆盖率达到96.8%。更多还原

【Abstract】 According to the demand of civil and military equipments, a novel modeling method was proposed to model three dimensional virtual human for ergonomics. Based on anthropometrical dimensions and three dimensional data, parametric regression analysis was adopted to construct virtual models, while correlation analysis and standard derivation was also employed. This method may be used to model standard segment or whole body of virtual human models, which can stand the samples greatly and enhance the total coverage of models. Meanwhile, these models are more similar with real body and more details were characterized. Based on this method, interactive software was developed using Qt. Taking the demand of garment for an example, ergonomic virtual human models for garment design were constructed by this software. 13 standard models were constructed by employing 12 relative parameters, and the theoretical coverage of these models reached 96.8%.更多还原
