AI Technical Summary

Technical Problem

In existing technologies, the detection of local high points in hot-rolled strip steel relies on manual visual inspection, which leads to poor accuracy of the judgment results and is prone to missed or misjudgment.

Method used

By acquiring the position and thickness of each detection point on the cross-section of the strip steel, calculating the vertical distance from the target detection point to the target straight line, and judging the thickness status of the detection point based on the vertical distance, the system automatically detects local high points, avoiding manual judgment.

Benefits of technology

It improves the accuracy and efficiency of local high point detection, automates the detection process, reduces human interference, and provides objective and reproducible results.

Abstract

The application discloses a hot-rolled strip steel local high point detection method, device, equipment and medium, and belongs to the metallurgical technical field.The method comprises the following steps: acquiring the positions and thicknesses of each detection point on a strip steel cross section; determining the perpendicular distances from a target detection point to each target straight line according to the positions and thicknesses of each first detection point, each second detection point and the target detection point, the target straight line being the line connecting the first detection point and the second detection point, the target detection point being any detection point among all the detection points, the first detection point being a detection point between the target detection point and a third detection point, the second detection point being a detection point between the target detection point and a fourth detection point, and the third detection point and the fourth detection point being located on the two sides of the target detection point; and determining the thickness state of the target detection point according to all the perpendicular distances, wherein the thickness state comprises a local high point state and a flat state.The method can automatically detect which detection points among all the detection points are local high points.
