Abstract

Remote sensing images of unusual dead pines were acquired at the heights of 430m and 700m by UAV (unmanned aerial vehicle) equipped with the visible light camera.The geographic location information collected by GPS was compared with the data processing information of ENVI software and the data processing information of interpretation.Six dead pine trees were identified by artificial screening and seven dead pine trees were identified by the NDVI value.Data extraction efficiency was 85.7%.The horizontal error was between 0.86 m and 4.20 m for geographical location information of the six dead pine trees obtained by remote sensing.The results showed that unmanned aerial vehicle remote sensing had basically realized the accurate location of pine trees dying from the pine wood nematode disease,which was of great significance for the early monitoring and later treatment of the pine wood nematode disease.
