Description

Technical Field

[0002] In construction and steel production, finished steel bars need to be standardized and packaged in bundles or distributed in fixed quantities according to the specified number and size. Therefore, steel counting becomes an indispensable link. At present, in the process of fixed-branch bundling or quantitative material distribution, steel bar counting mainly adopts manual counting and cross-sectional image processing, but both counting methods have defects, specifically: manual counting can ensure accuracy, but consumes a lot of manpower and financial resources. If manual visual counting is performed for a long time, it will cause great eye fatigue, which will lead to large errors in the calculation results. With the development of charge-coupled device technology, the problem of automatic steel bar counting is solved by collecting cross-sectional images of piled steel bars and using image processing methods. The accuracy and practicality of this method are based on the good pile-up processing of the bar cross section. Due to the poor bar collection environment, the image quality of the bar cross section is poor, and the cross-sectional overlapping and adhesion phenomenon is serious, which brings great difficulties to the layout of the image acquisition device, especially in some freight yards where the steel piles are surrounded by open space and the environment is poor. The conventional camera support connection method connected to the wall has the problem of difficulty in layout, such as the "an installation device and camera" disclosed in Chinese patent CN115325370B. The fixed connection method adopted by this technical solution is suitable for the layout of connecting rods such as electric poles, and is not suitable for the layout of some installation platform types.
