Description

Technical Field

[0001] The present invention relates to the field of steel inspection, and more particularly to a visualization processing system for hexagonal steel deformation analysis. Background Art

[0002] Hexagonal steel, also known as hexagonal steel, is a type of steel, also known as hexagonal bar, with a regular hexagonal cross section and a nominal length of opposite sides S. Hollow hexagonal steel is a steel pipe with an outer hexagonal shape. It is a type of special-shaped steel pipe. It is mostly used for the processing of nuts and mechanical accessories. Hollow hexagonal steel is a general term for steel pipes with a cross-sectional shape of an outer hexagon and an inner circle. There are welded special-shaped pipes and seamless special-shaped pipes. Due to the material, hollow hexagonal steel can be divided into ordinary carbon steel special-shaped steel pipes and stainless steel hexagonal pipes.

[0003] The hexagonal cross section of a hexagonal steel is the key data that determines the size of the hexagonal steel. By detecting whether the hexagonal cross section of a certain hexagonal steel is deformed from the hexagonal shape, it can be determined whether the hexagonal steel has a size deviation. However, since the hexagonal shape itself is difficult to identify the degree of deformation, and the prior art also lacks a high-precision analysis mechanism for the degree of deformation of the hexagonal cross section of hexagonal steel, there is a lack of key data for determining the size of the hexagonal steel. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides a visualization processing system for deformation analysis of hexagonal steels, which can identify the various component pixel points of a hexagonal section in a received recursive filtering picture, fit the various component pixel points to obtain corresponding image blocks, search for a portion matching a reference shape image corresponding to the hexagonal section on the shape curve of the image block as a first curve portion, search for a portion not matching the reference shape image corresponding to the hexagonal section on the shape curve of the image block as a second curve portion, determine the current distortion level of the hexagonal section according to the percentage of the first curve portion occupying the second curve portion, and when the determined current distortion level of the hexagonal section is greater than or equal to a preset level threshold, play an audio warning file corresponding to the excessive deformation of the hexagonal section of the hexagonal steel, thereby completing the intelligent identification of the degree of deformation of the hexagonal section of each piece of hexagonal steel.

[0005] According to the present invention, a visualization processing system for hexagonal steel deformation analysis is provided, the system comprising:

[0006] A directional pushing mechanism, used for pushing the hexagonal steel material whose cross section is to be inspected for deformation to the opposite side of the full-color camera mechanism and keeping the hexagonal cross section of the hexagonal steel material facing the lens plane of the full-color camera mechanism;

[0007] A full-color camera mechanism, used to perform a camera operation on the hexagonal cross section of the hexagonal steel material to obtain an instant full-color picture corresponding to a current timestamp;

[0008] A data enhancement device, connected to the full-color camera mechanism, for performing a density function-based histogram equalization process on the received real-time full-color picture to obtain and output a corresponding data enhanced picture;

[0009] A directional filtering device, connected to the data enhancement device, for performing directional filtering processing on the received data enhancement picture to obtain and output a corresponding directional filtering picture;

[0010] A recursive filtering device, connected to the directional filtering device, for performing adaptive recursive filtering processing on the received directional filtering picture to obtain and output a corresponding recursive filtering picture;

[0011] a continuous operation component connected to the recursive filtering device and comprising a front-end operation component, a middle-end operation component and a terminal operation component, wherein the middle-end operation component is located between the front-end operation component and the terminal operation component, and the continuous operation component is used to identify each component pixel point of the hexagonal cross section in the received recursive filtering picture, fit each component pixel point to obtain a corresponding image block, search for a portion matching the reference shape image corresponding to the hexagonal cross section on the shape curve of the image block as a first curve portion, search for a portion not matching the reference shape image corresponding to the hexagonal cross section on the shape curve of the image block as a second curve portion, determine the current distortion level of the hexagonal cross section according to the percentage of the first curve portion occupying the second curve portion, and the determined current distortion level of the hexagonal cross section is inversely correlated with the value of the percentage;

[0012] an audio alarm component connected to the continuous operation component, and used to play an audio warning file corresponding to excessive deformation of the hexagonal section of the hexagonal steel material when the current distortion level of the determined hexagonal section is greater than or equal to a preset level threshold;

[0013] Among them, the directional pushing mechanism is used to push the hexagonal steel whose cross-section is to be inspected for deformation to the opposite side of the full-color camera mechanism and keep the hexagonal cross-section of the hexagonal steel facing the lens plane of the full-color camera mechanism, including: keeping the hexagonal cross-section of the hexagonal steel parallel to the lens plane of the full-color camera mechanism.

[0014] Therefore, the present invention has at least the following four important inventive concepts:

[0015] Firstly, a continuous operating component including a front operating component, a middle operating component and a terminal operating component is used to complete a visual identification of the current distortion level of the hexagonal section, wherein the middle operating component is connected to the front operating component and the terminal operating component respectively;

[0016] Secondly: identifying each component pixel point of the hexagonal cross section in the received recursive filtering picture, fitting each component pixel point to obtain a corresponding image block, searching for a portion matching the reference shape image corresponding to the hexagonal cross section on the shape curve of the image block as a first curve portion, searching for a portion not matching the reference shape image corresponding to the hexagonal cross section on the shape curve of the image block as a second curve portion, and determining a current distortion level of the hexagonal cross section according to the percentage of the first curve portion occupying the second curve portion;

[0017] Again: determining the current distortion level of the hexagonal cross section according to the percentage of the first curve portion occupying the second curve portion includes: the determined current distortion level of the hexagonal cross section is inversely correlated with the value of the percentage;

[0018] Finally: the instant full-color image corresponding to the current timestamp obtained by performing a camera operation on the hexagonal cross-section of the hexagonal steel is continuously processed by density function-based histogram equalization, directional filtering and adaptive recursive filtering to obtain a recursive filtering image with better image quality, thereby providing more effective reference information for the subsequent visual identification of the deformation degree of the hexagonal cross-section of the hexagonal steel.

[0019] The visualization processing system for hexagonal steel deformation analysis of the present invention is simple to operate and widely used. Since the current distortion level of the hexagonal section can be determined according to the percentage of the first curve part occupying the second curve part, and when the determined current distortion level of the hexagonal section is greater than or equal to a preset level threshold, an audio warning file corresponding to excessive deformation of the hexagonal section of the hexagonal steel is played, thereby completing the intelligent identification of the degree of deformation of the hexagonal section of each hexagonal steel.
