Abstract

Abstract:

The low-altitude remote sensing technology of UAV has been widely used in the fields of emergency surveying and mapping due to its characteristics of flexible maneuverability, high efficiency, accuracy, and little constraint of climatic and airspace conditions. However, due to the complicated and harsh environment, high altitude and cold in the western mountainous area, single machine and single sensor acquisition technology failure to provide timely and efficient protection for emergency rescue, so it is urgent to upgrade the low-altitude remote sensing technology of UAV. Based on the surveying and mapping emergency practice of Sichuan province's, this paper has carried out a lot of research work on the plateau stability operation, single platform multi-sensor, high-speed transmission and other aspects. The achievements played an important role in the emergency surveying and mapping support work of Jiuzhaigou earthquake.

Key words: single machine multiple sensor, cluster collaboration, disaster geographical information, disaster spatial analysis
