> 中文摘要: 提出了一种三维人体的草绘建模方法,允许用户分层次绘制人体骨架线和轮廓线草图,并快速生成三维人体模型.该方法的特征主要表现在两个方面:首先,采用层次化的人体截面模板进行形变,并使用基于距离的描述子在人体模板库中检索最符合用户绘制的模板,使结果模型更能体现人体草图特性;其次,采用参数驱动的三维人体模型生成方法,将草图轮廓特征与模板轮廓进行对应并计算三维形变参数,最后对人体模板进行形变生成三维人体模型.实验结果表明,该方法能够快速构建符合用户绘制意图的三维人体模型.

Abstract:This paper presents a method of sketch-based human body modeling, which allows users to rapidly construct human model by sketching human skeleton and contours separately. The are two main features of our method: firstly, a multi-layered cross-section based human template is used to construct the result model, and a distance-based descriptor is computed in the model retrieval process to find the template most consistent with user’s sketch; secondly, a parameter-driven method of 3D human body modeling is used, it matches the sketch contour features and template contour features to compute 3D deformation parameters, by which the result model is constructed. The experiment result proves that the proposed method can rapidly construct 3D human body model which consistent with user’s intent.
