摘　　要：针对室内地图自动化提取方法缺失、生产效率与需求之间的矛盾日益加剧的现状,提出了一种基于CAD建筑平面图的室内地图制作方法。该方法首先利用建筑构件的语义信息和拓扑关系对室内要素进行筛选与提取;然后,恢复墙体的连通性,并从中提取墙体的中心线;最后,利用提取好的要素构建室内地图。以不同设计单位的CAD建筑平面图进行室内地图制作实验,结果表明,该方法有较高的适应性和鲁棒性,能够有效的制作室内地图。Aiming at the current situation of the lack of automatic extraction methods for indoor maps and the increasing conflict between production efficiency and demand,a method for making indoor maps based on CAD building plans was proposed.Firstly,the indoor elements were screened and extracted by using the semantic information and topological relationship of the building components.Then,the connectivity of the wall was restored and the center line of the wall was extracted.Finally,the indoor map was constructed by using the extracted elements.The indoor map making experiment was carried out with CAD architecture plans of different design units.The results show that the method has high adaptability and robustness,it can effectively make indoor maps.
