Problems solved by technology

[0002] In thermal power plants, the belt conveyor is the main equipment for conveying coal, but during the use of the belt conveyor, when the material on the conveyor belt is unevenly distributed or subjected to other external forces, the conveyor belt is prone to deviation. Phenomenon
Therefore, some manufacturers will use some equipment to place the conveyor belt deviation to prevent the conveyor belt from deviation, but in the actual use process, the use effect of these devices is not good

Abstract

According to the conveyor belt deviation diagnosis method and system based on machine vision, after the camera mechanism installed above the belt captures the picture of belt movement in real time, green laser rays on the rubber belt in the picture are extracted, and whether the belt deviates or not is judged according to the position movement of the green laser rays. A laser transmitter is additionally arranged above a belt, a high-definition camera is used for capturing scene pictures of belt operation in real time, algorithms such as image segmentation and characterization extraction are applied to the captured pictures, feature samples are trained and calibrated through a support vector machine, training learning of belt motion scenes is completed, therefore, the movement displacement of the laser rays in the image, namely the movement displacement of the adhesive tape, is detected in real time, and whether the belt deviates or not and the deviation direction are judged.

Description

technical field [0001] The invention relates to the technical field of image processing. More specifically, the present invention relates to a machine vision-based conveyor belt deviation diagnosis method and system. Background technique [0002] In thermal power plants, the belt conveyor is the main equipment for conveying coal, but during the use of the belt conveyor, when the material on the conveyor belt is unevenly distributed or subjected to other external forces, the conveyor belt is prone to deviation. Phenomenon. Therefore, some manufacturers will use some equipment to place the conveyor belt deviation to prevent the conveyor belt from deviation, but in the actual use process, the use effect of these devices is not good. Contents of the invention [0003] The purpose of the present invention is to provide a conveyor belt deviation diagnosis method and system based on machine vision. After capturing the photos of the belt movement in real time according to the ca...
