室内地图空间数据矢量化采集方法研究

摘要

Indoor map spatial data is the basis of indoor map visualization and base map vectorization is now the main way to acquire indoor map spatial data. Because spatial environment and object characteristics are obviously different between indoor and outdoor traditional vectorization method is not directly applicable to indoor map. Ac-cording to the characteristics and conceptual model of indoor map this paper studied the major flow and corre-sponding method for vectorially acquiring indoor map spatial data and analyzed the intelligent processing pattern for improving the acquisition efficiency. Finally combined with a developed test system this paper provided an application example of indoor map data acquisition.%室内地图空间数据是室内地图可视化表达的基础，底图矢量化是目前室内地图空间数据采集的主要方式。由于室内外空间环境及其对象特征存在较大差别，传统矢量化方法对室内地图的适用性较差。根据室内地图的特点和概念模型，研究了矢量化采集室内地图空间数据的主要流程与方法，重点分析了提高采集效率的智能化处理方式。最后，结合开发的试验系统给出了室内地图数据采集的应用示例。
