Problems solved by technology

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. Rainfall monitoring and early warning effect is better
However, at present, water level monitoring is becoming more and more difficult. Traditional metering equipment can no longer meet the needs of actual monitoring and early warning and flood prevention. Traditional cameras used to monitor water levels can only perform simple photo and video functions, and cannot pass the water level monitored upstream. Flood forecasting and early warning for downstream flood risk areas based on information

Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] A method for processing data from a water level monitoring and early warning camera, specifically comprising the following steps:

[0029] 1. In the camera data acquisition module, the OV5640 camera is used to obtain the water level image data and the water scale image. The OV5640 camera module uses a CMOS image sensor, and the CMOS can display colors through the color filters covering the pixels. Use R / G / B three kinds of filters to cover three pixels, ...

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...
