摘要 在地学信息图谱理论的基础上,应用数学形态学原理和方法建立了能够兼顾目标形状、尺寸和距离的方向关系模型,生成方向关系图谱并进行图谱分析。首先将源目标进行形态变换;然后选择方向关系的粒度,用变换后的源目标和参考目标相交区域面积的比值生成图谱,再根据设定的特征值(如均值、方差、熵等)进行方向关系图谱的分析;最后通过实例验证了该方法的正确性和可行性。 This paper presents a new method for describing directional relations based on their graph-spectrums by using the theory of the Mathematical Morphology.Directional relation graph-spectrums are generated based on the ratio of intersection area by original target and reference target which has been morphological transformation.Graph-spectrum analysis of directional relations is described according to a set of selected features,such as minimum,maximum,mean,standard deviation and entropy.Finally these new measures are experimentally evaluated.
