地铁工程地质剖面图典型图例符号自动识别研究

Automatic Recognition of Typical Legends on Metro Geological Section Map

地铁工程地质剖面图中包含施工安全风险辨识所需的重要信息,地质剖面图的自动识别是风险识别自动化系统的重要环节。论述了地铁工程地质剖面图图例的分类,图例识别面临的困难与识别可行性。以"黏土"和"粉质黏土"图例识别为例,描述了识别方法和详细算法。以武汉地铁2号线某车站围护结构地层信息识别为例,示范了图例识别的具体应用。

Important information for metro risk identification are contained in the geological section map of metro project,and the geological section automatic recognition is a core process for automatic risk identification system.In this paper,the categories of legends,the challenges and probabilities of legend recognition are described,the methodology and detailed algorithms of legend for ＂clay＂ and ＂silty clay＂ recognition are presented as an example.At last,an automatic legend recognition system applied to the project of a station on Wuhan metro Line 2 is presented.
