摘要
[目的]针对传统实地测量难以实现山区大面积套种烟草面积监控的问题,研究一种快捷、高精度的估测途径.[方法]利用EN-VI5.1软件处理资源三号卫星2.1m全色影像和5.8m多光谱影像,导入1:1万DEM数据进行正射校正以纠正地形起伏引起影像上的误差.野外获得具有代表性的地面控制点(GCP),利用面向对象分类方法,对影像进行智能化的分割和合并,以GCP的光谱、纹理和形状属性创建规则,进而提取烟草面积.[结果]经过分类后处理提取的研究区烟草面积为14 088.46 hm2,分类精度达到94.63%.[结论]面向对象分类方法提取遥感影像信息的实用性较高.
Abstract
[Objective] To find a rapid and high-precision estimation approach for estimation of the intercropped tobacco area in Mountainous Area.[Method] ZY-3 2.1 m panchromatic image and 5.8 m multispectral image were researched by ENVI5.1 software.Orthorectification was carried out by introducing 1: 10 000DEM data, so as to correct the image error induced by topographic relief.Representative ground control points (GCPs) were obtained in outdoor.[Result] Images were intelligently combined and divided by object-oriented classification method.Regulations were established based on the GCP spectrum, texture and shape properties.The tobacco area was extracted, which was 14 088.46 hm2.The classification accuracy reached 94.63%.[Conclusion] Extracting remote sensing images by object-oriented classification method had relatively high practicability.
