摘要
MODIS图像中Bowtie效应普遍存在,严重影响着数据的广泛应用和后续处理,因此Bowtie修正是MODIS图像处理必不可少的步骤。提出了基于网函数插值的MODIS图像Bowtie效应修正方法,其特点是利用MODIS Level 1B产品自带的地理纬度数据确定重复行数。应用个例表明,基于网函数插值的方法可以有效地对Bowtie效应进行修正,并且可以避免相关系数方法计算重复行数的不稳定性问题。
The ubiquitous Bowtie effect in MODIS images seriously affects the application and subsequent processing of MODIS images,so it is necessary to recitify Bowtie effect during MODIS image processing.Bowtie correction method based on net function interpolation is proposed,which determines the number of repetitive rows using the latitude included in MODIS Level 1B products.The examples show that the method effectively recitifies Bowtie effect as well as solves the instability of calculating the number of repetitive rows by correlative coefficient method.
