Abstract

The embodiment of the invention provides an industrial machine fault detection method and device based on machine vision, and the method comprises the steps: carrying out the image processing on an original image collected by a camera, and obtaining an image of a to-be-detected industrial machine; extracting features of each contour in the image of the industrial machine to be detected; and inputting the features of each contour in the image of the to-be-detected industrial machine into the fault detection model, and outputting a fault detection result corresponding to the to-be-detected industrial machine, wherein the fault detection model is obtained by training sample data of contour features of the mechanical structure image and a predetermined fault type label. According to the industrial machinery fault detection method and device based on machine vision provided by the embodiment of the invention, the fault detection result corresponding to the industrial machinery to be detected is obtained according to the feature of each contour in the image of the industrial machinery to be detected, a more accurate fault detection result can be obtained, and the fault diagnosis efficiency of industrial equipment can be effectively improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a machine vision-based industrial machinery fault detection method and device. Background technique [0002] Machine vision technology is a technology that replaces human eyes with machines to identify and detect. It collects images of items to be inspected through cameras, and after image signal processing, the detection results are recognized through system software. With the continuous development of automation technology, machine vision technology is widely used in industrial production inspection, especially for intelligent detection of industrial machinery failure. [0003] The existing machine vision-based industrial machinery fault detection methods often have false detections and missed detections during use, and the accuracy of detection results is low. Contents of the invention [0004] Embodiments of the present invention provide a method and device for detecting...
