Embodiment Construction

[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0023] Due to factors such as tension during the operation of the strip, vibration is inevitable, and it is easy to exceed the allowable range of vibration of the strip surface quality inspection equipment. Although the vibration of the strip steel is inevitable, the trend caused by the vibration can be used. If the steel strip approaches the same side of the camera, the measurement width will increase; if the strip steel moves to the opposite side of the camera, the measurement width will narrow. If there are cameras on both sides and the width measurement is carried out at the same time, the influence of the vibration of the strip on the superposition of the measuremen...

Abstract

The invention discloses a strip steel width measuring system based on machine vision. The strip steel width measuring system based on machine vision comprises line scan cameras arranged above and below strip steel respectively. The distances between the two line scan cameras and the strip steel are equal, the imaging range of each line scan camera covers the transverse edge of the strip steel, and the positions, irradiated by the two line scan cameras, of the strip steel are located on the same vertical plane. According to the strip steel width measuring system based on machine vision, the line scan cameras are arranged above and below the strip steel at the same time and carry out width measuring at the same time, and therefore a more accurate strip steel width measuring result can be given even when the steel strip shakes.

Description

technical field [0001] The invention belongs to the field of object width measurement, and relates to a strip steel width measurement system and method based on machine vision. Background technique [0002] Due to factors such as tension during the operation of the strip, jitter is inevitable, and it is easy to exceed the allowable range of the jitter of the strip surface quality inspection equipment. If there is a strip jitter, there will be a large measurement error. Contents of the invention [0003] In view of this, one of the objects of the present invention is to provide a strip width measuring system based on machine vision, which can still accurately measure the strip width when the strip shakes. [0004] One of the objectives of the present invention is achieved through the following technical solutions, a strip width measurement system based on machine vision, including line array cameras respectively arranged above and below the strip, two line array cameras and...
