| 摘 要： | 针对传统的点实体匹配方法的不足,提出了利用地标空间关系约束的点实体匹配方法。该方法以参考点实体、候选匹配点实体与其邻域内的同名地标之间的空间关系为基础构造距离特征向量和方向特征向量,基于距离特征向量和方向特征向量计算点实体的相似度,进而确定点同名实体。实验结果表明,该方法在点同名实体空间位置偏差较大的情况下依然能够取得很好的效果,验证了该方法的有效性。

| Abstract: | According to the disadvantages of the traditional point entity matching methods, the point entity matc-hing method based on spatial relation constraint of landmark was proposed in this paper. In this method, the dis-tance eigenvector and direction eigenvector were constructed based on the spatial relation between the reference point entity and candidate matching point entity with the same landmarks in their neighborhood. The similarity of point entity was calculated based on the distance eigenvector and direction eigenvector, then the same point entity was decided. Test results show that this method is able to have a good effect when the spatial position discrepancies between the same point entities is large. And the proposed method is validated by the experiments. |
