| 摘 要： | 香榧系第三纪孑遗植物,为我同特有的珍贵经济树种.常规的香榧资源调查方法存在工作量大、数据时效性差等不足.近年来高分辨率遥感影像的应用,为特定树种信息提取提供了可能.基于此,本文以高分辨率IKONOS卫星影像为基础,采用面向对象的信息提取方法,多尺度分割形成对象后,利用光谱、形状、纹理等构建特征空间,进行会稽山区香榧信息提取的试验,并与常规监督分类法(最大似然法)进行了比较.结果显示,基于面向对象方法的香榧信息提取精度达到86.57%,比监督分类法的精度提高了27.90%.研究表明,用面向对象的分类方法进行香榧信息提取和资源调查是可行的.

| Abstract: | Torreya grandis Merrillii is tertiary relict plant,and is a precious economic species peculiar in China.The conventional plant resource survey is time-consuming and cost-expensive,so it is difficult to update in time.The high spatial resolution images have more spatial details and texture characteristics,and offer the possibility to extract information of a particular tree species.In this study,an object-oriented technology was introduced to extract the information of Torreya grandis Merrillii from IKONOS i... |
