摘　　要：针对具有廊道式空间的建筑物的室内导航路网模型构建问题,结合建筑物内部元素的几何、语义、拓扑三类信息,利用室内环境的空间几何特性进行室内导航路网模型构建研究。主要包括:匹配走廊边界线中若干对距离较近的平行线对并提取其中轴线以形成骨架通道网络;通过对偶变换将房间、门等元素抽象表达为点对象,并按其实际连通关系连接边对象与点对象,由此形成完整的室内导航路网模型。应用结果表明:该算法对构建室内导航网络具有一定的实用价值。For construction problem of indoor navigation network model of buildings with corridor space, the geometric combining semantic and topological information of internal elements in the building, spatial geometrical characteristics of indoor environment are applied to construct the indoor navigation network model, which mainly includes matching several pairs of parallel lines coming from corridor boundary lines within relatively close range of distance, and extracting the medial axis of the corridor to form the skeleton passage network;representing concrete elements, such as a room or a door,with point objects through dual transformation;and connecting arc objects to point objects according to their actual connection relationship. The complete indoor navigation network model is formed finally. It is verified by application that this algorithm is useful for constructing an indoor navigation network.
