Quickbird卫星影像的阴影检测及提取方法研究的开题报告摘要：Quickbird卫星影像具有高空间分辨率和高光谱分辨率的优点，在城市环境信息的提取与更新等领域有广泛的应用。然而，在进行遥感图像解译的过程中，常常需要进行阴影提取。本论文主要研究Quickbird卫星影像的阴影检测及提取方法，采用了一种基于灰度变换的方法，并结合光谱和纹理特征，确定了适当的阈值，较好地解决了影像中的阴影问题。研究结果表明，所提出的方法具有较高的精度和可行性。关键词：Quickbird卫星影像；阴影检测；阴影提取；灰度变换；光谱特征；纹理特征第一章绪论1.1研究背景及意义1.2国内外研究现状1.3研究内容和方法第二章Quickbird卫星影像的阴影检测及提取方法2.1影像预处理2.2阴影检测方法2.2.1基于灰度变换的方法2.2.2结合光谱和纹理特征的阈值确定2.3阴影提取方法第三章实验数据及结果分析3.1实验数据3.2实验结果分析第四章结论与展望4.1结论4.2展望参考文献Abstract:Quickbirdsatelliteimageryhastheadvantagesofhighspatialresolutionandhighspectralresolution,andhasawiderangeofapplicationsintheextractionandupdatingofurbanenvironmentinformation.However,shadowextractionisoftenrequiredduringremotesensingimageinterpretation.ThispapermainlystudiestheshadowdetectionandextractionmethodofQuickbirdsatelliteimagery,adoptingamethodbasedongrayleveltransformation,andcombiningspectralandtexturefeaturestodetermineappropriatethresholds,whicheffectivelysolvestheshadowproblemintheimage.Theresultsshowthattheproposedmethodhashighaccuracyandfeasibility.Keywords:Quickbirdsatelliteimagery;shadowdetection;shadowextraction;grayleveltransformation;spectralfeature;texturefeatureChapter1Introduction1.1Researchbackgroundandsignificance1.2Domesticandforeignresearchstatus1.3ResearchcontentandmethodsChapter2ShadowdetectionandextractionmethodofQuickbirdsatelliteimagery2.1Imagepreprocessing2.2Shadowdetectionmethod2.2.1Methodbasedongrayleveltransformation2.2.2Determinationofthresholdscombinedwithspectralandtexturefeatures2.3ShadowextractionmethodChapter3Experimentaldataandresultanalysis3.1Experimentaldata3.2ExperimentalresultanalysisChapter4Conclusionandprospect4.1Conclusion4.2ProspectReferences
