Fast Identification of Ground Objects Based on Different Heights of Unmanned Aerial Veh icle(UAV)Hyper spectrum
摘要
Abstract
Ab stract [Objective]The aim was to study the changes of spectral characteristics of ground objects at different heights and the method of ef-fective and rapid identification of ground objects at different altitudes and in different periods.[Method]Based on the 200 m altitude hyper-spectral image on August 7,2016 and 100 m,200 m,300 m altitude hyperspectral image on September 25,2016, we studied the changes of spectral characteristics of ground objects at different heights and the classification accuracy of ground objects at different altitudes and in differ-ent periods.[Result]Under different heights, vegetation spectral reflectance of significant difference, as the height increases, the vegetation characteristic features such as 'green peak' reduce,'Red Valley' elevated, 'red edge'appears 'red shift', in the near-infrared range, spectral reflectance decreased.Considering artificial participation,processing time and classification precision,and so on,we could know that based on ISODATA method could be realized rapid recognition of ground objects at different heights and different periods.[Conclusion]The results provide reference for the use of unmanned aerial vehicle(UAV)hyperspectral remote sensing application in other areas.关键词
