Abstract

The invention provides a conveyor belt slipping detection method, system and device based on computer vision. The method comprises the steps that a first image of a conveyor belt is acquired, and the corresponding acquisition time is recorded; setting an ROI (Region of Interest) in the first image, and identifying coordinates of preset points of the ROI to form an image template; based on a preset image acquisition frequency, obtaining a plurality of conveyor belt images and corresponding time, matching the plurality of conveyor belt images with the image template, and obtaining a movement distance of each conveyor belt image relative to the image template; and calculating the running speed of the conveying belt based on the moving distance and the time difference, comparing the running speed with a set speed, and judging the slipping of the conveying belt. Through a non-contact mode, multiple images in the conveying process of the conveying belt are obtained, real-time speed detection of the conveying belt is achieved based on image processing, the slipping phenomenon is judged in time, corresponding countermeasures can be taken conveniently, and safe operation of the conveying belt is guaranteed.

Description

technical field [0001] The invention relates to the technical field of video image processing, in particular to a method, system and device for detecting conveyor belt slippage based on computer vision. Background technique [0002] When the conveyor belt is used to transport materials, if the friction between the roller and the conveyor belt is not enough, the conveyor belt is prone to slipping. However, in the mining industry, the installation location of the conveyor belt is mostly outdoors. In cold weather, icing and condensation will occur. At this time, the friction between the conveyor belt and the roller is reduced, and slippage is very easy to occur. In addition, the tension of the conveyor belt is not enough, the load is started, the friction coefficient of the roller surface is not enough, etc., which may cause the slippage of the conveyor belt. [0003] After the conveyor belt slips, it will seriously affect the progress of material transportation. When the conv...
