提出采用有向属性关系图描述道路交叉口结构,形成典型道路交叉口结构模板库。通过将道路网矢量表示转化成有向属性关系图表示,采用图匹配技术识别道路网中的典型交叉口。实现有关算法,通过试验验证该方法的有效性,并分析其局限性和适用范围。该方法可在基于结构的交叉口简化过程中用于典型交叉口结构识别。 更多还原

【Abstract】 The focuses are on the recognition of structures of typical road junctions,which can facilitate structure-based simplification of junctions.It is based on the observation that a road junction is a designed functional structure that consists of functional elements and the composition of elements often has a structural pattern.A typical road junction can therefore be represented by means of structural description and recognized by means of structural pattern recognition.The structural patterns of ... 更多还原
