| 摘 要： | 针对图像数据库中空间查询的需求,将拓扑关系和方向关系结合,在二维投影间隔空间关系模型基础上,提出了一种新的拓扑、方向关系的度量方法。所提出的度量方法提高了空间关系相似性的度量精度,从而有效地提高了图象对象空间关系查询的准确性。

| Abstract: | In the paper,more precise spatial relationship model based on2-D project interval relationship is described.A new kind of similarity measurement between spatial relationship is proposed.The measurement is more reasonable than traditional methods.The model we present have more ability to represent spatial relationship than traditional model. |
