基元识别

Primitive recognition on the base of combined relationships between primitives
基于形体组合关系的基元体识别技术研究
After analyzing the current algorithms , the problems existed in them and the root reasons lying behind are discussed . then the primitive recognition and interpretation are taken as the research emphasizes of this dissertation
本文通过对已有工程图样理解算法的分析，探讨了其中存在的问题及其原因，将研究内容重点放在基元体的识别、理解方面。
The class acquisition of expression mode semantics , projection relationship semantics and dimension constraint semantics , and integration acquisition technology of tangency combined relationship , interpenetrate combined relationship and intersected combined relationship are emphatically introduced , which lay the foundation for further primitive recognition
重点介绍了表达方式语义、投影关系语义和尺寸约束语义的分类获取技术，以及相切组合关系、相贯组合关系、截交组合关系语义的整合获取技术，为后续基元体信息的识别、理解和获取奠定基础。
