摘要: 为解决空间数据检索效率低、准确性差的问题,本文提出由空间对象形状描述模型、空间关系描述模型、场景相似性自适应计算模型构成的场景相似性检索方法.空间对象形状描述模型精准检索满足样例对象形状约束的数据库对象,提高空间对象形状的识别精度.空间关系描述模型检索满足样例场景关系约束的数据库场景,提高空间关系的描述精度.场景相似性自适应计算模型对满足形状及关系约束的完全匹配、局部匹配场景进行打分、排序,增加检索结果相似性打分的合理性.模拟场景、真实场景的实验表明本场景相似性检索方法具有良好的检索性能.

Abstract: To solve the problem of low efficiency and poor accuracy on spatial data retrieval,this paper proposes a scene similarity retrieval method based on spatial object shape description model,spatial relationship description model and adaptive scene similarity computing model.Spatial object shape description model can accurately retrieve database objects satisfied with the sample object shape constraints,and improve the space object shape recognition accuracy.Spatial relationship description model can retrieve database scenes satisfied with relationship constraints of the sample scene,and improve the spatial relationship description precision.Adaptive scene similarity computing model can mark and sequence complete or incomplete matching scenes satisfied with shape and relationship constraints,improve the rationality of similarity scores on retrieval results.Experiments of simulative and real scenes show the scene similarity retrieval has a good retrieval performance.

Key words: spatial data retrieval, shape description, spatial relation description, spatial-scene similarity
