Automatic water level extraction method and system based on reservoir monitoring camera

Abstract

The invention discloses an automatic water level extraction method and system based on a reservoir monitoring camera. The standard size of a reservoir is monitored based on image data provided by the reservoir monitoring camera, and the water level is automatically extracted through an image processing method. On the premise that precise water level data are provided, corresponding water level image data are provided, and key pixel training extraction, edge detection extraction, clustering analysis, denoising and water level segment detection are conducted on the image data so that the function of automatically calculating water level data on the basis of camera data can be achieved. According to the automatic water level extraction method and system based on the reservoir monitoring camera, on the basis that the reservoir monitoring camera executes a monitoring task, water level value calculation and extraction are automatically conducted on monitored images, an existing water level data extraction process is simplified, reservoir water level real-time monitoring and data acquisition are achieved on the premise that no hardware facilities are added, and the water level extraction method and system can be widely applied to reservoir production practice.

Description

technical field [0001] The invention belongs to the field of image data identification and information extraction, and in particular relates to a water level automatic extraction method and system based on a reservoir camera. Background technique [0002] Water level information is one of the most important hydrological data in the process of reservoir management. The current methods of obtaining water level information are mainly divided into bubble type water level gauge, pressure type water level gauge, radar type water level gauge, etc. [0003] The current water level gauge has the following deficiencies in the process of obtaining the water level of the reservoir: [0004] (1) Specially built water level information acquisition equipment is required, which is expensive and difficult to maintain; [0005] (2) Only a single water level information is provided, ignoring the demand for water level image information. Contents of the invention [0006] In order to solve ...
