基于Landsat数据的海上油气开采平台提取方法研究
Research on Extraction Method of Offshore Oil and Gas Production Platform Based on Landsat Data
摘要
Abstract
In view of shortcomings of extracting offshore oil and gas production platforms using remote sensing images,a meth-od for extracting offshore oil and gas production platforms based on Landsat 7 images is proposed.Firstly,the landsat 7 image is pre-processed with radiometric correction and land mask,and then the sea water and thick clouds are removed by threshold segmenta-tion method,and the offshore oil and gas production platform is extracted.Then,the cloud positon difference is used for overlay analysis to remove the false alarms such as thin clous and ships.The final overlay frequency calculation and analysis method is used to classify the production platform and screen the offshore oil and gas production platform.The sea area at the border of Brunei and Malaysia is selected as the research area.Throuth 8 Landsat images from 1999 to 2008,61 oil and gas platforms have been detected,including one located in the nine-segment line of China,with a longitude and latitude of(4°47′1.6″N,113°28′23.3″E).The re-sults have reference value for China to master underwater obstacles and ensure the navigation safety of ships.关键词
