摘要: 针对室内三维地图中数据检索效率不高的问题,提出了一种基于八叉树的室内三维地图数据检索方法。首先,根据八叉树的场景分割方法对数据进行存储;然后,对数据进行编码以方便寻址;其次,为数据添加房间隔断约束条件对检索数据进行筛选;最后,对室内地图数据进行检索。与不具有约束条件的搜索方法相比,搜索代价平均降低了25个百分点,且搜索时间更加稳定。所提方法可以显著地提高室内三维地图数据的应用效率。

Abstract: To solve the low efficiency problem of data retrieval in indoor three-dimensional (3D) maps, an indoor 3D map data retrieval method based on octree was proposed. Firstly, the data was stored according to the octree segmentation method. Secondly, the data was encoded to facilitate addressing. Thirdly, the search data was filtered by adding a room interval constraint to the data. Finally, the indoor map data was retrieved. Compared with the search method without constraints, the search cost of the proposed method was reduced by 25 percentage points on average, and the search time was more stable. Therefore, the proposed method can significantly improve the application efficiency of indoor 3D map data.

Key words: 3D indoor map, map data, octree, neighbor search, closedness constraint
