| 摘 要： | 文章以湄公盆地周边海域为研究区，利用遥感技术手段，综合多时相、多源卫星数据，探讨不同数据源海上油气井平台提取方法。本次研究，首先基于1992—2018年27景多时相夜间灯光数据和2019年两期SAR数据，分别采用高斯滤波法和双参数CFAR法，实现了全区域油气井平台的自动化提取；然后，针对有确定性资料辅助判定的区域，采用人工目视解译的方法，对长时间序列Landsat-8 OLI及YG24号光学卫星影像进行提取，并将解译结果作为标准数据，用于验证前两种自动提取方法的精度。结果表明：夜间灯光影像数据易获取、成本低，提取方法简单，而SAR影像提取结果的精度高、流程烦琐，建议根据多源卫星数据的特点相互结合，实现快速、高效、精确的信息提取，应用于海上油气井平台监测。

| Abstract: | In this paper, the waters around the Mekong Basin were taken as the study area and the methods for extracting offshore drilling platforms were discussed. These methods utilized multi temporal and multi-source remote sensing image. Firstly, the study automated the extraction of drilling platforms by using Gaussian filtering method and two-parameter CFAR method, respectively, based on 27 scenes of multi-temporal nighttime lighting data 1992-2018 and two periods of SAR data in 2019. Then, for areas with deterministic information, visual interpretation was used to extract drilling platforms from long time series Landsat-8 OLI and YG24 optical satellite images. The results were used as standard data to test the accuracy of the previous two methods. Results showed that Nighttime lighting data was easy to obtain, low cost, and simple to extract information. However, the accuracy of SAR image extraction results was higher, but the process was cumbersome. In practice, according to the characteristics of multi-source satellites, it was recommended to combine the advantages of each other to optimize the extraction process and improve the accuracy of the results. |
