[0090] Based on the above-mentioned first embodiment, the abnormal vibration detection method of the coal conveyor belt in this embodiment includes in the step S20:

[0091] Step S21: converting the monitoring image of the coal conveyor belt into a grayscale image.

[0092] In the specific implementation, the gray scale of the monitoring image of the coal conveyor belt is to carry out weighted average according to the sampling values ​​of each channel of the image. The monitoring image of the coal conveyor belt is usually in RGB format, and the method used for grayscale is:

[0093] Formula 3;

[0094] In Formula 3, Gray is the grayscale value, R is the red channel value, G is the green channel value, and B is the blue channel value.

[0095] After graying each pixel in the monitoring image of the coal conveyor belt, a grayscale image is obtained.

[0096] Step S22: denoising the grayscale image to obtain a smooth image.

[0097] In order to eliminate the influence of pi...

Abstract

The invention belongs to the technical field of image processing, and discloses an abnormal vibration detection method, device, equipment and storage medium of a coal conveying belt. The method includes: acquiring a monitoring image of a coal conveying belt; converting the monitoring image of a coal conveying belt into a belt edge image; determining a target edge image according to the belt edge image and a preset image area; determining the belt in the target edge image Edge line segment: judge whether there is abnormal vibration of the coal conveying belt according to the edge line segment of the belt. Through the above method, the image of the coal conveyor belt is recognized to identify the belt edge, and the belt edge part is recognized from the image to obtain the belt edge line segment, and whether there is abnormal vibration is judged according to the belt edge line segment, and whether there is abnormal vibration of the belt can be continuously detected through the image. Thereby, the detection efficiency of abnormal vibration is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method, device, equipment and storage medium for detecting abnormal vibration of a coal conveyor belt. Background technique [0002] Coal handling device refers to the device for transporting coal. Its installation form can be divided into two types: coal transport corridor and coal transport trestle. The coal delivery corridor is similar to the trench, which is generally an underground or semi-underground concrete structure. The conveyor is installed in the corridor, and the coal is transported by the conveyor through the corridor. , Some are closed and some are not closed, and the coal is transported by a conveyor. Its transportation methods include belt conveying, pneumatic conveying and pipeline conveying, etc., and belt conveying is the most widely used. [0003] The deviation and abnormal vibration of the belt will affect the efficiency of coal transportation,...
