基于哨兵一号影像海岸线自动提取方法研究

Research on Automatic Extraction Method of Coastline Based on Sentinel-1

通过研究近年来边界提取方法,提出一种适用于Sentinel-1的算法,结合形态学处理的海岸线自动提取方法,并在原有方法的基础上做了部分改进。然后利用该方法对基于Sentinel-1多年的连云港海岸线进行提取及分析,并进行了实测数据的验证比较,精度较高,效果比较理想。

Based on the research of boundary extraction methods in recent years, we proposed an automatic coastline extraction method based on sentinel-1 algorithm combined with morphological processing,and made some improvements on the basis of the original method. Then, we used this method to extract and analyze the coastline of Lianyungang coast based on sentinel-1 for more than a year, verified and compared the measured data. The accuracy can meet the standard, and the effect is relatively ideal.
