Water level detection method based on vision algorithm

Abstract

The invention provides a water level detection method applied to a mine field, which is used for monitoring the water level of a mine field reservoir. The method includes a software part which comprises image data acquisition, an image processing algorithm, data calculation and information output; and a hardware part which comprises a camera and an industrial personal computer. The camera sends animage to the industrial personal computer in real time or the industrial personal computer processes the image data, filters the received image data, and then performs color space conversion to obtain color space data of the image; the color space data is filtered, adaptive calculation is performed through hue, brightness and saturation by using an Otsu algorithm to obtain a binary image of the data meeting the requirements, smoothing processing is performed on the image based on the obtained binary image, and binary image conversion is performed by using the obtained image data; an abstractmodel with a binary image being the water level is established; the water level is calculated through the binary image; and action is determined according to the water level information. According tothe invention, an online automatic monitoring function for the water level condition in a pool is realized, and the quantity demand for attendants and inspectors is reduced.

Description

technical field [0001] The invention relates to the field of mine safety intelligence, in particular to a water level detection method based on a visual algorithm. Background technique [0002] With the development of mine production, mine production should increasingly consider the direction of intelligence. In order to measure the water level in the pool of the mine, it is necessary to use a water level gauge. However, most of the current water level gauges are contact type, which are easy to cause pollution and are easily affected. Corrosion, damage, and even electric leakage have safety accidents, so an intelligent monitoring method is needed for non-contact automatic monitoring. Contents of the invention [0003] The purpose of the present invention is to provide a water level detection method based on a visual algorithm, thereby solving the problem of automatic monitoring of the water level of a pool in a mine. [0004] In order to achieve the above object, the tech...
