Embodiment Construction

[0022] The system of the present invention is divided into two parts: hardware design and software design. The hardware design part mainly completes the ingestion and collection of chain images, and generally consists of lighting devices, cameras and image acquisition cards. The software part mainly includes preprocessing, threshold segmentation, binarization and other operations on the collected chain image to complete the feature extraction of the chain image. The implementation of the invention equipment in the factory requires a mainstream industrial control machine (configuration not lower than CPU main frequency 2.0G, memory 2G, hard disk 500G), an image acquisition card with a development kit, a uniform speed transmission belt 3 meters long, step The motor and gearbox ensure that the conveyor belt rotates at a constant speed. There are two rows of LED linear dot matrix light sources with a length of about 3 meters, distributed on both sides of the conveyor belt. Two CCD ...

Abstract

The invention discloses a transmission chain quality detection system based on machine vision. The transmission chain quality detection system comprises a to-be-detected transmission chain, a lighting source, a CCD (Charge Coupled Device) camera and a lens, an image processing unit, a computer and a display, wherein the CCD camera is used for focusing an image of the to-be-detected transmission chain to a CCD chip through the lens, the image forms a video signal (an image signal) after being filtered and amplified to be output to the image processing unit, and the image processing unit is used for transmitting the image to a computer storage for processing; the computer completes analysis, image processing and storage of acquired data and image information to obtain a quality parameter of the to-be-detected transmission chain, and the obtained quality parameter is compared with a calibrated parameter so that decision and control are completed, and the function of automatic identification is further realized. According to the transmission chain quality detection system based on machine vision, the detection processing speed is greatly increased, the labor intensity is reduced; the length of the transmission chain which can be detected by one transmission chain quality detection system within 1 second reaches about above 4m.

Description

technical field [0001] The invention relates to a transmission chain quality detection system based on machine vision, belonging to the technical field of transmission chain quality detection. Background technique [0002] In industrial production sites, transmission chains are often used to convey products. Whether the quality specifications of the chain meet the product standards will determine whether it can be used in the manufacture of industrial products, and especially in products such as engines and elevators. The quality requirements are particularly high. For the quality inspection of the chain, the traditional manual method is very time-consuming, labor-intensive, and can no longer meet the modern high-precision and high-efficiency inspection requirements. It is necessary to combine a new technology to develop a new real-time and efficient inspection system. The machine vision inspection technology has the advantages of non-contact, online real-time, fast speed, ...
