Problems solved by technology

It is precisely because of the improvement of automation and intelligent technology that it is often unattended, which leads to the failure of a certain function to be discovered in time.
In addition, in the conveying system, although the video monitoring equipment is also running, its actual significance is only video monitoring, and it is necessary to manually observe the monitoring images to find and judge whether the conveyor belt is off-track

Abstract

The invention discloses a method and device for judging deviation of a conveying belt. The method comprises the following steps of: obtaining multiple frames of original images, and calculating the original difference image of any two frames of original images; obtaining the three-primary colour difference of each pixel point in the original difference image, comparing each colour difference of each pixel point with a first set threshold, taking the coordinate value of the pixel point of which at least one colour difference is greater than the first set threshold as a foreground classification sample, and forming a foreground classification sample set by using a plurality of the foreground classification samples; obtaining multiple frames of detection images, and obtaining a foreground detection sample set according to the same processing procedure; and comparing the foreground detection sample set with the foreground classification sample set, and judging that the conveying belt deviates if different samples exist. According to the invention, whether the conveying belt deviates is automatically judged through the comparison between real-time acquired images and the original images, thus avoiding possible human errors in judgement only based on manual video surveillance; therefore the method and the device are more reliable and stable in the aspect of timely fault finding.

Description

technical field [0001] The invention belongs to the technical field of video image information processing, and in particular relates to a method and device for judging deviation of a conveyor belt based on video image processing. Background technique [0002] The conveyor belt is the key equipment of the conveying system, and its safe and stable operation directly affects the production operation. The deviation of the conveyor belt is the most common failure of the belt conveyor. Light deviation will lead to material spreading, affect the production progress and damage the conveyor belt and related mechanical equipment; The running resistance of the conveyor belt is increased due to the deviation of the conveyor belt, which may cause serious accidents such as mine fires and casualties. [0003] With the continuous improvement of automation technology and the continuous development of communication and control technology, the conveyor belt monitoring technology is also gradu...
