Belt detection algorithm based on machine vision

Abstract

The invention discloses a belt detection algorithm based on machine vision. The algorithm comprises the following steps: A, firstly, reading a video frame through a camera; and A1, surface image collection is conducted on the surface of the belt through a camera, and the clear degree of the collected image is judged. According to the method, real-time tear detection is carried out by adopting the RGB camera, the hardware cost is effectively reduced, the problem that extra hardware cannot be installed in a special scene is effectively solved, the miss detection situation possibly occurring in a neural network is optimized theoretically, the key effect on belt breakage early warning is achieved under the condition that the real-time performance and the accuracy are guaranteed, the problems that a belt tearing detector and a laser auxiliary method cannot detect small tearing under a belt, small tearing is often a preposed factor evolved into large tearing, small tearing detection is very key, and a third method is large in false detection and missing detection probability and not suitable for industrial use due to the fact that a sample is very small are solved.

Description

technical field [0001] The invention relates to the technical field of belt detection, in particular to a machine vision-based belt detection algorithm. Background technique [0002] There are three types of industrial belts: industrial transmission belts, automotive transmission belts and conveyor belts. The first two belong to transmission belts. Transmission belts are used to transmit mechanical power, including flat transmission belts and triangular transmission belts. They are composed of rubber and reinforced materials. The layer is made of rubberized canvas, synthetic fiber fabric, cord and steel wire, etc., which are laminated with rubber and then formed and vulcanized. Widely used in various power transmissions, the transmission belt is the power generated by the rotation of the motor or engine of the prime mover, and is transmitted to the mechanical equipment through the pulley by the tape, so it is also called the power belt, which is the core connecting part of t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a belt detection algorithm based on machine vision, which has the advantages of real-time accuracy and solves the problem that belt tear detectors and laser-assisted methods cannot detect small tears under the belt, and small tears often evolve into The pre-factor of large tearing, so the detection of small tearing is very critical, and the third method is because the sample is very small, so the probability of false detection and missed detection is relatively high, and it is not suitable for industrial use.
