摘要
研究了基于层析数据的特征识别技术。针对反求工程中存在的瓶颈问题,通过合理地选择特征参数和函数,连续、定量地描述了造型特征,并将多个特征函数的变化特征进行组合匹配,应用智能决策等手段,实现了原型特征的识别,并在此基础上构造了原型三维CAD模型。
The feature recognition method based on slicing data is investigated. According to the bottleneck in reverse engineering (RE) and by choosing the relevant feature parameters and functions, the feature of modeling is described continuously and quantitatively. Combining and matching the transformation nexus of feature multifunetion are made. By using the expert system (ES), the feature recognition for the model is accomplished. Based on the above-mentioned ideas, 3D CAD model can be constructed.
