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 a-daptive scene similarity computing model.Spatial object shape description model can accurately retrieve database objects satis-fied with the sample object shape constraints,and improve the space object shape recognition accuracy.Spatial relationship de-scription 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 re-sults.Experiments of simulative and real scenes show the scene similarity retrieval has a good retrieval performance.关键词
