| Abstract: | The aerial remote sensing(RS) by unmanned aerial vehicles(UAV),which is flexible and quick, showed great
benefits in data collection for the area mi pacted by 5·12Wenchuan earthquake. A framework of3D visualizationmanage-
ment system forUAV remote sensing mi age has been developed. There are fourparts in this3D visualization system: flight
tracking design system, remote sensing mi age acquiring system, mi age processing system, and 3D visualizationmanagement
system. The flight tracking system provides the tools to design flightpath forUAV in a 3-D visualization environments. The
flightpath design can be loaded into theUAV flightpath controlsystem to control theUAV direction, speed, and so on. The
remote sensing mi age acquiring system is to acquire remote sensing mi agesby controlling the attitudes and camera actions of
the aerial vehicles. The mi age processing system includes the functions of mi age distortion correction and registration. The
3Dmanagement system handles themanagement and 3D visualization ofUAV mi ages. The key technologies regarding the
system are discussed. The high-resolution remote sensing mi ages are used as base mi ages, and the geometric correction and
Gray-Scale transformmethods are employed to change originalUAV remote sensing mi ages to new ones in geographic coordi-
nate system. UAV remote sensing mi agesaremanaged by spatial index in 3D visualization environmentwhich hasmulti-scale
remote sensing mi ages from different satellites. The paper establishes the quadtree pyramid and LOD model formanaging
large volume remote sensing data, which can providemore fluentvisualizationwhen usersnavigate in the 3D virtual environ-
ment. A 3D visualization management system forUAV remote sensing mi ages has been mi plemented based on the VGE-
3DGlobeEarth platform. From the expermi ental results, the system workswellwhen itmanages and visualizes theUAV re-
mote sensing mi ages in the areas mi pacted by5·12Wenchuan earthquake. With regard to the roles ofUAV remote sensing
in the5·12Wenchuan earthquake rescue, it is argued thatUAV remote sensing mi ages acquiring and visualizationmanage-
ment system can be a very mi portantsupporting tool forquick response ofemergentevents such as floods, earthquakes, forest
fires, and environmental pollution earthquakes. |
