Rolling strip steel strip head curvature detection method and system, medium and electronic terminal

Abstract

The invention provides a rolled strip head curvature detection method and system, electronic equipment and a medium. The method comprises the steps that strip steel image information is acquired; training a neural network based on deep learning according to the strip steel image information, and obtaining a target detection model for identifying the position of the strip steel; collecting a stripsteel picture of a steel rolling field, and inputting the strip steel picture into the target detection model to obtain strip steel position information; the strip head of the strip steel is positioned according to the strip steel position information, and contour information of the strip steel is obtained; obtaining a minimum bounding rectangle of the maximum contour according to the contour information; judging the curvature of the strip head of the strip steel according to the distance between the minimum enclosing rectangle and the upper boundary of the strip steel; according to the method, the curvature of the hot-rolled strip head in the strip steel rolling scene is detected without manual participation, the method has the characteristics of real-time performance and high precision,the labor cost is reduced, the working efficiency is improved, the detection reliability is ensured, the steel rolling quality is improved, and the effect is extremely good in the actual industrial scene of hot-rolled strip steel.

Description

technical field [0001] The invention relates to the fields of metallurgy and image processing, in particular to a method, system, medium and electronic terminal for detecting the curvature of a rolled strip head. Background technique [0002] In the rolling process of hot-rolled strip steel, affected by factors such as the temperature difference between the upper and lower surfaces of the slab, the difference in diameter between the upper and lower rolls, the difference in rotational speed, and the deformation rate, etc., it often causes strips or buckles ( warped head), which affects the quality of rolled steel, so it is necessary to detect and judge the curvature of the hot-rolled strip head in time. [0003] At present, in the rolling work of hot-rolled strip steel, the detection and judgment of the curvature of the hot-rolled strip head still rely on manual visual inspection. In the actual work process, it is usually necessary for the staff to observe the strip head cur...

Problems solved by technology

In the actual work process, it is usually necessary for the staff to observe the strip head curvature through the remote camera to identify the rolling condition of the strip. There will be fatigue of the supervisors, high supervision costs, complex construction site conditions and easy omissions, etc. A series of problems, therefore, need a new hot-rolled strip head curvature detection method, which can automatically detect the curvature under the premise of ensuring accurate detection, so as to overcome the above technical problems
