Problems solved by technology

It is necessary for tailings workers to measure the length of the dry beach on the spot. In this way, the manual measurement of the dry beach length not only has large errors and low accuracy, but more importantly, the obtained data is not obtained by real-time and continuous measurement.
As a result, it is difficult for the leaders of the mining area to grasp the safety technical indicators of the tailings pond in a timely manner. These factors have greatly affected the safety management of the tailings pond

Embodiment Construction

[0022] The method of the present invention is illustrated in conjunction with the accompanying drawings.

[0023] A method for calculating the length of tailings pond dry beach based on image recognition, the specific recognition method is as follows:

[0024] Firstly, the pictures of the dry beach of the tailings pond are as follows: figure 1 Perform binarization processing, the binarization processing of the image is to set the gray value of the pixels on the image to 0 or 255, that is to say, the whole image presents an obvious black and white effect. Image thresholding segmentation is one of the most commonly used and simplest image segmentation methods, which is especially suitable for images in which the target and background occupy different gray scale ranges. It can not only greatly compress the amount of data, but also greatly simplify the analysis and processing steps, so in many cases, it is a necessary image preprocessing process before image analysis, feature ext...

Abstract

The invention discloses a method for calculating the length of the dry sand of a tailings reservoir based on image recognition, which comprises the following steps: binarizing a dry sand image of the tailings reservoir through image recognition technology so that the dry sand image is more simple, a data size is reduced and the outlines of a dam body of a tailings dam and the dry sand are shown; processing and analyzing the binarized dry sand image and utilizing pixel detection technology to calculate and analyze the height of the dry sand to further analyze accurate required data results; and finally utilizing the recognized height of the dry sand and a slope to calculate the length of the dry sand of the tailings reservoir. In the method, the image recognition technology is utilized to accurately divide the dry sand image of the tailings reservoir; data obtained by analysis and calculation is accurate; the accuracy of the calculated length of the dry sand is relatively higher and real-time property is relatively stronger; and the requirements of the online and real-time monitoring of the length of the dry sand of the tailings reservoir are met.

Description

technical field [0001] The invention relates to an image recognition technology, in particular to a method for calculating and measuring the dry beach length of a metal or nonmetal mine to a tailing pond. Background technique [0002] The length of the dry beach of the tailings pond is an important indicator to measure whether the tailings pond can survive the flood season safely, and it is also one of the important factors to evaluate whether the tailings pond is safe. Finding a suitable image processing technology to process and analyze the dry beach image of the tailings pond to obtain the accurate dam crest height of the tailings pond, and then calculate the length of the dry beach of the tailings dam becomes the automation safety of the development of the tailings pond The primary task of the monitoring system. [0003] At present, the measurement of dry beach length mainly relies on manual methods. During the flood season, the water level in the tailings reservoir ar...
