Description

technical field [0001] The invention belongs to the technical field of imaging adjustment, and more particularly, relates to an imaging adjustment device and method for the surface of a round steel. Background technique [0002] With the development of the market economy, the requirements for product quality continue to increase, and it is particularly important to quickly test products online. For steel products, CCD cameras are mostly used to quickly scan and image the appearance of steel products online, and compare and identify with the map in the standard library to judge the quality of the product. At present, many iron and steel enterprises have successfully developed on-line detection systems for the surface quality of steel products with regular shapes, such as continuous casting billet surface quality on-line detection systems, strip surface quality on-line detection systems, etc. However, due to the circular section of round steel, It is necessary to place multip...

Problems solved by technology

[0004] One is a substrate surface detection method and equipment disclosed in CN1568419A, the core of which is to provide a reflection image of at least one target above the surface, which is detected by digital processing of local phases along two directions. The digital processing is used to calculate the local slope changes and then deduce the surface curvature changes or height changes according to these changes. This method can only be used for the detection of conventional slabs, and is not suitable for the detection of round steel;

[0005] The second is a strip surface detection method and device disclosed in CN1508535A. The method is mainly used together with a panoramic camera and a high-resolution scanning camera. The movable scanning camera scans and enlarges the detection of the local area, which can not only detect the more obvious defects, but also detect the smaller surface defects of continuous production, so as to improve the accuracy of the detection of strip surface defects. The result of the whole device is simple, But it is not suitable for testing round steel;

[0006] The third is a surface detection device and surface detection method disclosed in CN1696672A, which mainly includes an irradiation unit that irradiates light onto the surface, and a detection unit that detects the intensity of the reflected light on the surface. The method mainly judges the surface quality by detecting the intensity of the reflected light , this method has high requirements on the shape of the steel and can only be used for the detection of conventional slabs;

[0007] The fourth is a surface detection device disclosed in CN1892202A and a surface detection method using the detection device. The device mainly includes a transfer rod that is isolated from the detection surface of the detection object and has a light-emitting part and a light-receiving part that are respectively combined at both ends of the transfer rod. The optical sensor of the part, and the light sensor used to send and receive light in a direction parallel to the detection surface of the detection object at a predetermined distance from the detection surface of the detection object, the driving part and the position adjustment part, etc., the device can detect the upper surface or bottom surface of the substrate impurities, but it has high requirements on shape, so it cannot be used for round steel detection

[0008] In summary, there is currently no technology that can effectively solve the problem of round steel surface detection and imaging.
