Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0045] An embodiment of the present application provides a method for extracting waterlogging risk points, which is executed by a computer, such as figure 1 shown, including the following steps:

[0046] S101. Obtain waterlogging data corresponding to multiple rainfall data in the target area.

[0047] In this step, the target region can be selected by administrative region or by natural region. A natural region refers to an area with relatively consistent natural geographical components within a certain range. In this embodiment of the application, a certain city may be selected as the target region.

[0048] Multiple rainfall data correspond to multiple different rainfall situations. The rainfall data can include rainfall int...

Abstract

The invention discloses an inland inundation risk point extraction method and device, and relates to the technical field of risk prediction. The method comprises the steps of obtaining waterlogging data corresponding to multiple rainfall data of a target region, and extracting waterlogging risk points of the target region according to the waterlogging data corresponding to the multiple rainfall data. According to the waterlogging risk prediction method and device provided by the invention, the waterlogging risk points can be accurately extracted before waterlogging occurs.

Description

technical field [0001] The present application relates to the technical field of risk prediction, in particular to a method and device for extracting waterlogging risk. Background technique [0002] With urban expansion and global climate change, the problem of urban waterlogging is becoming more and more serious. Pre-identifying urban waterlogging risk points is a prerequisite for effective prevention of waterlogging risks. [0003] In related technologies, waterlogging points are generally identified by installing waterlogging monitoring equipment, but this method needs to accurately determine which locations are possible waterlogging spots in advance in order to install waterlogging monitoring equipment. Waterlogging points can also be extracted by collecting Internet data. For example, when a heavy rain occurs in a city, collect relevant information such as telephone calls, videos, and pictures, and use geographic information systems, deep learning and other technologies...
