【摘要】 利用汶川地震中获取的遥感影像,采用三角棱柱表面积法对影像中的不同地物进行分维数的计算。计算结果证明,影像中同一区域各个波段计算出来的分形维数不同,波段质量对分形维数影响较大;分形特征能够区分不同破坏程度的建筑物、滚石与其他地物。更多还原

【Abstract】 The triangular prism surface area method was used to analyze fractal dimension of the different ground objects in remote sensing images obtained from Wenchuan %M%s8.0 earthquake.The experimental results show that fractal dimensions values in same region of optical image are different,image quality has great influence on fractal dimension and that fractal feature is able to be used for distinguishing the different degree of building damage,rolling stones and others.更多还原
