Unmanned aerial vehicle monitoring method and system for urban flood scenes

Abstract

The invention discloses an unmanned aerial vehicle monitoring method and system for urban flood scenes. The monitoring method comprises the following steps: a panoramic video and an inclined image ofthe urban flood scene are acquired by an unmanned aerial vehicle monitoring system; further, according to the inclined image, the submerging range and the submerging depth of the city are obtained incombination with a digital elevation model before a flood disaster, and the real scene of the flood disaster degree of each region of the city is acquired in real time by utilizing the panoramic video, thereby providing the urban flood disaster information comprehensively and timely.

Description

technical field [0001] The invention relates to the field of flood monitoring, in particular to an unmanned aerial vehicle monitoring method and system for urban flood scenes. Background technique [0002] Flood disaster, one of several natural disasters in the world, seriously threatens the safety of human life and property, and affects social stability and development. In China, due to the unique distribution of geological conditions, a large number of floods occur every year, large or small, except for deserts, extreme drought and alpine regions, about 2 / 3 of the land area has different degrees and different types Flood disasters: the eastern region is often hit by floods caused by storm surges during the flood season (June-September each year); mountainous, hilly and plateau regions often have torrential torrents and mudslides due to heavy rain; the Yellow River, Songhua River and other rivers Floods are sometimes caused by icing; snowmelt floods sometimes occur in Xinj...

Problems solved by technology

[0004] For the monitoring of flood disasters, the traditional method of relying on manual means to monitor the disaster situation is not only inefficient, time-consuming and laborious, but also cannot be monitored on the spot in many places. Moreover, flood disaster monitoring is often faced with the threat of heavy rain, and the monitoring task cannot be carried out. The development of satellite technology has solved the above problems, and the application of geographic information, global positioning, and remote sensing can comprehensively improve the digital level of drainage and flood prevention

[0005] In flood disasters, in order to allow decision makers to understand the flood situation accurately and in a timely manner, it is necessary to provide comprehensive, accurate and fast information, such as monitoring of DEM of submerged areas, submerged range, residential areas, houses, roads and bridges, etc. However, floods are often short-lived, and flood fighting and rescue work need to be carried out quickly. Various satellite sensors often perform their own duties, each has its own advantages and disadvantages, so it is impossible to provide comprehensive information in a short time
