The system of linear dimension parameter detecting.
Background technology
Square and rectangular pipe is very extensive as a kind of steel application, in Chinese this big steel country, in occupation of very heavy
The status wanted.In the production process of square and rectangular pipe, due to many reasons such as former, processing technique so that produce
The size of the square and rectangular pipe for coming can produce certain error, while can also make square and rectangular pipe surface the defects such as pit, scratch occur,
The square and rectangular pipe quality for causing domestic production hardly results in good guarantee, constrains the sound development of steel market.Middle Chinese
People republic national standard《GB/T 6725-2008 cold-rolled forming sections》And National Standard of the People's Republic of China《GB/T 6728-
2002 structures cold-bend hollow profiled bar size, profile, weight and tolerance》Clear stipulaties have been done to physical dimension.Survey at present
The method of dimension pipe profile is mainly hand dipping, by instruments such as slide gaugies, measures for big specification square and rectangular pipe
Difficulty is big, precision is low.Therefore, the square and rectangular pipe size and Surface Quality Inspection System based on machine vision is developed with very heavy
The meaning wanted, realizes that square and rectangular pipe size and the automatic online real-time detection of surface quality also have and can not estimate to iron and steel enterprise
The effect of amount.
Square and rectangular pipe size and Surface Quality Inspection System based on machine vision can realize supermatic detection,
The labor intensity of staff can greatly be reduced, recruitment cost, improve production efficiency is reduced.Have benefited from computer high speed
Disposal ability and the omnibearing detection of Vision Builder for Automated Inspection, the testing result for finally giving will more science and comprehensively, also more
Plus easily form comprehensive evaluation report.The product of different quality grade is provided according to different clients group, can not only be significantly
The dispute produced because of quality problems is reduced, economic loss is it also avoid, the benefit of iron and steel enterprise is improve, the comprehensive of enterprise is enhanced
Close competitiveness.Due to being non-contact measurement, detecting system will not have any contact between tested square and rectangular pipe, and it is
By camera acquisition target image, therefore tested square and rectangular pipe will not be had any impact in measurement process.
Using the line-structured light technology of machine vision, the precision of measurement can not only be improved, while also causing measuring system
More simple and stable, in addition, such to combine the measurement for being also beneficial to large scale square and rectangular pipe.For large scale side's square
The measurement of shape pipe, needs the cooperating of multiple cameras, it is therefore desirable to which the image that each video camera shoots is carried out into global mark
Fixed, unified in a world coordinate system, the three-dimensional information for so obtaining can really react the feature of square and rectangular pipe.
