基于知识的工程图识别模型研究

Study on Knowledge-based Model of Engineering Drawings Recognition

对人工读图的认知过程进行了分析,总结出其自组织的特征,设计了"基于知识的工程图识别层次模型",将整个工程图识别过程分为像素、矢量图元和工程图形三个层次,层次之间相应地进行基于知识的两阶段的矢量化和识别处理,该模型为各种工程知识的使用打下了基础。

Based on the analysis of human recognition process, the self-organiztional character of the process is summarized and a common recognition model is designed. The model is ＂knowledge-based hierarchy model＂ which divides the engeeing drawing into three levels： pixel representation, basic vectors and figures. Upon the levels the 2-phase processing, knowledge-dericted vectorization and recognition, can be carried out as well as other algorithms.
