摘要
建筑结构图CSD的语法识别方法存在对噪声和差错的敏感性强以及通用性较差等局限 ,本文对此提出了两点改进方法。一方面 ,CSD中图形符号之间的关系得到了充分的重视。相互关联的符号分为核心符号和导出符号两类 ,彼此间关系紧密的所有核心符号被结构化为一个全局符号加以识别。导出符号的识别以核心符号为基础。另一方面 ,用图形符号在建筑结构领域背景下的语义控制和指导核心符号与导出符号的识别。
Syntax method for graphic symbol recognition of construction structure drawings has two main drawbacks: sensitivity to noise and error, and bad generality. In this paper, two improvements are proposed. On the one hand, close attention is paid to the relationship between graphic symbols. Those symbols interacting with each other are classified to kernel symbols and deduced symbols. Kernel symbols are recognized as a whole and deduced symbols are recognized on the base of kernel symbols. On the other hand, the semantic of the graphical symbols in the background of construction structure field is used to control and direct the recognition of both kernel symbols and deduced symbols.
