摘    要:针对以农田为主的某地区的航空影像,利用图像差值和比值法分析比较了取不同阈值时的变化检测效果;最后采用实际的航空影像进行实验比较,证明使用两种方法集成的检测结果比单独使用其中一种更准确.

关 键 词:图像差值  图像比值  变化检测  航空影像

Abstract:In this paper,the change detection methode of utilizing aviation images' grey level difference and ratio was mainly studied.In order to analyse this two kinds of methods,a group of aviation images taking farmland as main landscape of the whole view was measured.According to the result of experiments presented by the form of black-and-white pictures,while relatively choosing different threshold value,these two kinds of methods were compared,especially in the use of detecting the result through the change of ...
Keywords:grey level difference  grey level ratio  change detection  aviation image
