Airborne flood data processing method, device and system based on aviation emergency mode

Abstract

The invention provides an airborne flood data processing method, device and system based on an aviation emergency mode, and the method comprises the steps: carrying out the image mosaic based on an earth observation image, and obtaining a target image; inputting the target image into a water body recognition model to obtain a water body recognition result; based on the water body recognition result and the geographic information data, spatial analysis is carried out, and comprehensive flood analysis information is obtained; and when the aircraft lands, the comprehensive flood analysis information is sent to a remote terminal, so that the remote terminal receives the comprehensive flood analysis information, carries out preliminary study and judgment on the disaster situation, and guides and generates a rescue command decision. According to the airborne flood data processing method, device and system based on the aviation emergency mode, splicing, correction, information extraction and the like of flood data can be completed in real time and quasi real time on the aircraft during flight, after the aircraft lands, the information is transmitted to a ground command system, the information processing efficiency and the instantaneity are improved, and the method, the device and the system are suitable for popularization and application. The significance on emergency rescue is obvious.

Description

technical field [0001] The present invention relates to the technical field of aviation remote sensing, in particular to an on-board flood data processing method, device and system based on aviation emergency mode. Background technique [0002] At present, as one of the main natural disasters, flood disasters cause huge casualties and economic losses every year. For flood emergency rescue work, the basic information of the disaster situation in the affected area should be mastered first, and the general assessment of the disaster situation should be completed to provide necessary guidance information for rescue. [0003] However, during floods, it is often accompanied by heavy rain or cloudy weather. Optical satellite remote sensing cannot continuously collect ground image data during the rescue period due to weather restrictions. Microwave remote sensing satellites have a certain ability to penetrate clouds and rain, but due to the technical difficulty of data processing. ...
