【摘要】 提出了基于工程结构简图语义知识的计算机结构模式识别方法。根据框架结构特征,融快速模板匹配、语义识别和树文法遍历方法为一体,对结构计算简图几何拓扑形式和荷载环境进行识别,进一步生成应用软件所需的数据文件,从而屏蔽了应用软件原始数据文件的具体格式。更多还原

【Abstract】 An approach of computer geometric pattern recognition, which is based on semantic knowledge of an engineering structure sketch, is presented in this paper. The approach for recognizing geometrical topology and load environment in an engineering structure analysis sketch combines fast template matching, semantic recognition and the traversal of tree grammar, and then generates the data files which are required by application software. Therefore ,the specific format of initial data files of application software can be masked.更多还原
