A UAV monitoring method and system for embankment and dam failure scenarios

Abstract

The invention discloses an unmanned aerial vehicle monitoring method and an unmanned aerial vehicle monitoring system for a dam burst scene. The unmanned aerial vehicle monitoring method comprises steps that an unmanned aerial vehicle with fixed wings flies according to a first preset airline, and a first scene image of dam burst is acquired; edge detection on the first scene image is carried outto acquire the submerging range and the breach coordinate of the breached dam; the number of the rotor unmanned aerial vehicles is determined according to the submerging range and the breach coordinate, and each rotor unmanned aerial vehicle is controlled to fly along a second preset airline corresponding to the rotor unmanned aerial vehicle, and a plurality of sub-scene images and scene videos ofeach breach are acquired; Finally, the plurality of sub-scene images are spliced to acquire the second scene image of the dam burst; the disaster information of the dam burst is acquired according tothe second scene image and the scene video of each breach. According to the invention, the disaster information can be rapidly and accurately acquired by the unmanned aerial vehicle remote sensing technology, and the requirements of timely emergency monitoring are satisfied.

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 embankment and dam failure scenes. Background technique [0002] Every time a dam collapse accident occurs, there are hundreds or even thousands of casualties, causing great losses to the local economy. If it is washed away, a large amount of sediment carried by it will also cause soil desertification and soil salinization, which will be a devastating damage to the local natural environment and ecological environment. [0003] In order to reduce the harm caused by the break of dikes and dams, we can start from two aspects. On the one hand, it is to predict and prevent dike and dam breaks; on the other hand, it is to carry out rapid emergency treatment and disaster relief after the occurrence of dike and dam breaks. [0004] Due to the suddenness of dam breaks, it is difficult to predict when and where dam breaks will oc...

AI Technical Summary

Problems solved by technology

[0008] Although remote sensing measurement technology has been widely used in river channel evolution and flood disasters, for short-duration flood disasters such as embankment and dam breaks, satellite remote sensing image data not only has a long data acquisition period, but also has a difficult time phase, which cannot meet timely emergency monitoring. needs
