Abstract

The invention provides a water level monitoring and early warning camera data processing method, which comprises the following steps of: firstly, acquiring image information by using a camera, acquiring water level image data, obtaining a water gauge image, and processing and digitizing the image information to obtain corresponding water level information; secondly, analyzing and comparing with disaster forming water level data in recorded national mountain torrent disaster investigation and evaluation results, analyzing whether the current upstream water level causes flood disasters to each downstream risk area or not, and generating an early warning signal; and finally, transmitting the early warning signal to a downstream risk area through a communication module. According to the invention, the requirements of actual monitoring and early warning flood prevention are met, water level information is fed back in time, and an early warning signal is generated through data analysis and comparison, so that flood early warning is conducted on downstream flood disaster dangerous areas.

Description

technical field

[0001] The invention relates to a water level monitoring and early warning camera data processing method, which belongs to the field of water level monitoring technology and early warning technology. Background technique

[0002] Flood disasters are widespread, destructive, and difficult to defend, which affect human life and property safety. Effective flood warning is one of the important measures to reduce losses. Commonly used methods at home and abroad include rainfall monitoring and early warning and water level / flow early warning. The forecast period of rainfall monitoring and early warning based on rainfall is short, and the influence of rainfall temporal and spatial distribution and previous rainfall is not fully considered, and the effect of rainfall early warning is not very good; the early warning based on water level / flow can fully consider the influence of the above factors, and the forecast period and accuracy of early warning are relatively low...
