摘  要:
以塔河地区的HSI高光谱遥感数据为基础,结合相关的统计学知识,利用非监督分类法和混合像元分解法分别提取森林植被类型,并对其进行精度检验。得出非监督分类总体精度为70. 78%,混合像元分类的精度为76. 87%。结果表明混合像元分解定量解算植被类型是更有效的方法。

摘  要:
Based on the hyperspectral remote sensing image( HSI) data of the Tahe County,Heilongjiang Province,and combined with relevant statistical knowledge,unsupervised classification method and mixed-pixel decomposition method are employed to extract the forest vegetation types. Accuracy test is conducted through the second class survey data of Tahe in 2012. The accuracy of unsupervised classification method is70.78% and that of mixed pixel decomposition method is 76.87%. The result show that mixed pixel decomposition of quantitative elements is more effective to calculate the vegetation types.
