摘要
针对STEP AP242提出了多视图语义模型,在此基础上进行语义本体化实现对产品几何与非几何语义信息的统一;然后提出了一种基于边界特征的轻量化算法,该算法在保留产品非几何信息的前提下,裁剪产品模型,简化三角面片,降低数据复杂度;最后给出了实验数据分析以证明该算法的可行性。
Based on the STEP AP242 protocol,which supported product model definition exchanges,a multi-view semantic model was proposed to classify and keep the non-geometric informations.With the model,semantic ontology was implemented to unify the product geometry and non-geometric semantic informations.Then a boundary-based lightening algorithm was proposed to match the performance of mobile terminals,which might cut product model with the product non-geometric information kept.Finally the experimental data was given to prove the feasibility.
