摘要

摘要:
北冰洋航路是未来全球航运的重点开拓领域,海冰运动对北冰洋航路开发有重要影响。本文利用风云三号卫星中分辨率光谱成像仪(FY-3/MERSI)数据的特点和优势,研究北冰洋流冰自动提取和运动跟踪的方法。首先在分析流冰灰度分布特征的基础上,提出分区域阈值分割与梯度差分相结合的方法实现块状流冰提取,然后根据块状流冰的多种几何特征匹配同名流冰并计算其运动速度。应用这种方法跟踪2011年6月弗雷姆海峡流冰运动,跟踪结果与美国国家冰雪数据中心提供的极地网格化日均海冰运动矢量整体趋势一致,验证了方法的有效性。这种方法获取各块流冰实际运动速度,可以有效弥补网格化海冰运动平均速度场分布和细节的不足,为北冰洋航路开发提供更详细的流冰运动信息。

Abstract:
Sea ice motion adversely plays an important role in the developing the Arctic Passage which is essential for commercial global shipping. This paper developed an automatic extraction and tracking method for Arctic drift ice based on the FY-3/MERSI data that obtained by Medium Resolution Spectral Imager onboard FengYun-3 satellite. Firstly, on the basis of the gray distribution feature of drift ice, the blocky drift ices were extracted by combining sub-region bimodal threshold segmentation with gradient differential technique. Secondly, the matching of same drift ice in pair images was implemented according to the geometric feature and the velocity of the matched ice was calculated. A series image of the Fram Strait was used to compute the drift ice motion. The resulting motion vectors were found to match well with the polar daily grid sea ice motion vectors provided by the National Snow and Ice Data Center, thus verifying the validity of the proposed method of tracking drift ice motion. The prime effect of this method is effectively supplying the actual motion vector of drift ice to improve the distribution and details of grid sea ice motion vectors. So this method is capable of providing comprehensive and detailed information support of the sea ice motion for the Arctic Passage development.
