Industrial mineral aggregate conveying belt material shortage abnormity monitoring method based on machine vision

Abstract

The invention provides an industrial mineral aggregate conveying belt material shortage abnormity monitoring method based on machine vision, and the method comprises the steps: obtaining an industrial conveying belt monitoring video image, carrying out the feature enhancement of an abnormity monitoring image in a complex environment, employing a belt region-of-interest two-step extraction method fusing the features of two regions, extracting a belt region-of-interest, adopting an edge detection method to extract the edge of the mineral aggregate on the surface of the belt, adopting a gray-level co-occurrence matrix to analyze the texture information of the surface of the belt, and adopting a gross error processing method based on a Grubbs criterion method to carry out data preprocessing on the extracted image feature quantity; and fusing the belt surface texture information and the mineral aggregate edge information by adopting a weighted sorting radar map method, and judging the material shortage abnormity of the industrial mineral aggregate conveying belt. According to the method, the material shortage abnormity of the industrial mineral aggregate conveying belt can be judged faster, more accurately and more comprehensively, and the method has great significance in improving the production efficiency and reducing the abnormal influence range.

Description

technical field [0001] The invention relates to the technical fields of machine vision, image processing and abnormality monitoring, in particular to a machine vision-based method for monitoring low-material abnormality of industrial mineral material transportation belts. Background technique [0002] Belt transportation of industrial mineral materials is a relatively common industrial transportation method. In actual production, the industrial mineral material conveying belt is often forced to stop the operation of the production line for maintenance due to the abnormality of low material or the related reaction caused by the abnormality. Therefore, it is very necessary to find the abnormality of low material in time and eliminate it. [0003] The abnormal monitoring video of the industrial mineral material transportation belt is a direct manifestation of the belt transportation status. For a certain belt transportation process, the abnormal monitoring video image of the in...

Problems solved by technology

[0008] The invention provides a machine vision-based method for monitoring the abnormality of low material in industrial mineral material transportation belts. Abnormalities are monitored. Due to the irregular periodic movement of the industrial mineral material transport belt in the lateral direction and the interference of the external environment, the area of ​​interest of the belt cannot be accurately extracted, and there are many abnormal factors affecting the operation of the industrial mineral material transport belt. The operation of the industrial mineral material transport belt The problem of slow and poor accuracy in anomaly recognition
