摘要 为了扩展三维模型的应用方式与范围,在将基于模型的定义数据集定义为三维注释模型的基础上,提出了三维解释模型的概念。通过对工程知识分类、组织与存储技术的论述,提出构建三维解释模型的三维模型知识标注方法。该方法采用向量空间模型表达和处理异构知识,以意图知识作为输入,实现半自动式三维模型知识标注。通过原型系统的开发与实现,以发动机燃油喷头为例展示三维模型知识标注方法,验证了所提方法的有效性。 To extend the scope and application of 3D models,annotating engineering knowledge to 3D model had become a trend.On the basis of defining Model Based Definition(MBD)data set as 3Dannotation model,the concept of 3D elucidation model was put forward.Through the discussion on engineering knowledge classification,organization and storage technology,3D model knowledge annotation method was proposed which used to construct 3Delucidation model.In this method,the heterogeneous knowledge was represented and processed with vector space model,and the intention knowledge was taken as the input to realize the semiautomatic 3D model knowledge annotation.Through the development and implementation of prototype system,3D model knowledge annotation method was demonstrated by the example of engine fuel injector,which proved the validity of the proposed method.
