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

Embodiment Construction

[0032] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] First, a brief description of the technical idea of ​​the present invention: For the long-distance conveyor belt used in the production site, in order to ensure the smooth operation of the conveyor belt, a plurality of pairs of rotating shafts are respectively arranged under the left and right sides of the conveyor belt, which are called the left and right sides of the conveyor belt. Side shaft and conveyor belt right shaft. The left edge of the left rotating shaft and the right edge of the right rotating shaft are respectively located outside the left edge of the conveyor belt and the right edge of the conveyor belt, and the positions of the rotating shafts are fixed. In this way, the left axis of the conveyor belt and the right axis of the conveyor belt can be used as reference edges to obtain the a...

Abstract

The invention discloses a method for detecting conveyor belt deviation based on image edge extraction. The method comprises the following steps of: collecting original images; acquiring image information; detecting edge profiles; repairing the edge profiles; extracting edges; marking the edges; calculating a deviation distance; and determining the deviation degree. The edge profiles of the original images collected by video equipment are detected and repaired until conveyor belts in the images and the edges of rotating shafts are extracted, and whether the conveyor belts are deviated is detected through the extracted edges; and the accuracy of deviation detection is improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for detecting deviation of a conveyor belt based on image processing, and more specifically relates to a method for detecting deviation of a conveyor belt based on image edge extraction. 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 communi...
