A method for automatic feeding of square detection based on machine vision

Abstract

The invention discloses an off-square detection automation feeding method based on machine vision, and relates to the field of mechanical automation. The method comprises the steps that a machine vision recognition system recognizes four coordinates of the outline of a reference object; the machine vision recognition system calculates two hidden lines according to the four coordinates of the reference object and determines a horizon; the machine vision recognition system recognizes the outline of the end face of a steel billet to determine four vertex coordinates of the end face; the machine vision recognition system determines whether the contour line section of the reference object is parallel to the end surface contour line section of the steel billet and judges whether the steel billetis an off-square billet; and if the machine vision recognition system judges that the steel billet is the off-square billet, the operation of automatically removing the steel billet can be executed.The method based on machine vision is utilized to intelligently identify the off-square billet of a feeding rack, and the identified off-square billet is automatically removed, so that the heating rhythm of a heating furnace is stabilized, the steel piling risk of a production line is reduced, and the operation rate of the production line is improved.

Description

technical field [0001] The invention relates to the field of mechanical automation, and more specifically refers to a machine vision-based automatic feeding method for square detection. Background technique [0002] The steel rolling heating furnace occupies an important position in the iron and steel enterprises. Its task is to heat the steel slab so that the temperature and temperature distribution of the steel slab meet the rolling requirements. The feeding device of the heating furnace is a device for transporting the billet to the heating furnace. It is mainly composed of a feeding platform, a steel retaining hook, a steel fork and a conveying roller table. In the charging billet, the falling billet is always an important hidden danger affecting the heating and production of the heating furnace. Every year, accidents such as stacking of steel in the rolling process and furnace shutdown caused by billet stripping directly affect the operating efficiency of the productio...

Problems solved by technology

The control process of this application is only to judge which line the billet enters, and it is impossible to judge whether the billet is out of square or deformed, and the impact on the billet out of square cannot be estimated
