Applications of remote sensing images processing of unmanned air vehicle on the low attitude in quick acquirement of geological disasters information in Wenchuan earthquake

ZENG Tao①②,YANG Wu-nian①②,JIAN Ji①②(①College of Earth Sciences of Chengdu University of Technology,Chengdu 610059,China; ②Institute of Remote Sensing & GIS,Chengdu University of Technology,Chengdu 610059,China)  
in affected areas of Wenchuan earthquake relief work,the earthquake emergency command group set up by many relevant functional departments of china for the first time applied mass of different resolution and high-resolution remote sensing image of key areas by UAV or helicopters and other aviation platforms carrying a variety of sensors.Those data provide supports and information assurances for comprehensive,rapid and accurate grasping the disaster seismic and decision-making of seismic experts at all levels of leadership.In these paper,through comparative analysis of low-altitude UAV remote sensing image characteristics,the author explored the low-altitude UAV remote sensing image rapid processing method and provided a solution ideas for post-disaster emergency in the low-altitude UAV remote sensing images of uncontrolled and rapid correct image matching and stitching.Moreover by using the object-oriented remote sensing image information on the rapid automatic classification and information extraction method,achieved the purposes of rapid investigation of information extraction of geological disasters and quickly identify landslide,mud-rock flows and other geological disasters body spatial location and evaluation.
