面向手机3D动画自动生成的空间分层布局规划

手机3D动画自动生成系统是将用户发送的短信，经过信息抽取、情节规划等一系列的处理，最终生成一段与短信内容相关的三维动画并发送给接收方这一过程.布局规划是系统的一个重要组成部分，其功能是将模型放置到场景的可用空间上.通过对布局问题的研究，本文提出了一种基于区域布局和模型布局的分层布局方法，其包括定性规划和定量计算两个部分，利用语义网技术建立分层布局知识库，基于规则的方法推导出分层布局定性规划方案，并对模型位置进行动态计算.最后，通过实验验证了分层布局规划的有效性和多样性，满足了自动生成系统对布局规划的要求.

Spatial Hierarchical Layout Planning for Mobile 3D Animation Generation

Based on messages sent by users, the 3D animation automatic generation system of mobile phone, after a serial process of information extraction, plot planning, would generate a video animation and send it to the receivers. The layout planning is an important part of the automatically generated system, which can place the model to the space on the animation scene. Through the study of layout problems, this paper proposes a hierarchical layout method based on the regional and model layout. It includes qualitative planning and quantitative calculation, using semantic web technology to build hierarchical layout knowledge base, derivation of hierarchical layout qualitative planning scheme based on rule, dynamic calculation of model location. Finally, experimental results show that the hierarchical layout planning is effective and diverse, and it meets the requirements of automatic generation system for layout planning.
