Abstract:
Sentinel-2 MSI(multispectral instrument,MSI)was used as data source,and multi-scale object-oriented analysis was used as basic method to study and analyze typical characteristics of plastic greenhouse and other ground objects at different segmentation scales.A set of greenhouse index was established,and a method of plastic greenhouse extraction was proposed based on greenhouse index set.The method was validated by experiment of plastic greenhouse extraction in Weifang City,Shandong Province.The producer precision,user precision and overall Kappa coefficient of the method were 96.6%,89.2% and 0.9 respectively.The accuracy results showed that the method could be effectively applied to research of plastic greenhouse extraction.
