Ultra-large type plate shearing machine plate shearing edge curve detection system and method

Abstract

The invention discloses an ultra-large type plate shearing machine plate shearing edge curve detection system and method. The plate shearing edge curve detection system mainly comprises an optical imaging unit, an image acquisition and processing unit and a main control computer. The plate shearing edge curve detection method includes the following steps: first, CCD sensors and lenses which are installed on an ultra-large plate shearing machine are utilized to perform real-time image acquisition on a plate shearing edge under cooperation of strip-shaped light sources; after preprocessing of collected images, the images collected by adjacent industrial cameras are spliced, an image edge is detected after edge burrs are removed, and finally a coordinate axis and coordinate points are selected and a fitting technology is utilized to detect an actual machining curve of a sheared plate. The ultra-large type plate shearing machine plate shearing edge curve detection method utilizes image real-time acquisition and image processing technologies to detect the plate shearing edge curve, and the detection method can achieve higher detection precision and detection efficiency compared with a traditional detection method.

Description

technical field [0001] The invention relates to a system and method for detecting the shear edge curve of a super-large shearing machine, which is mainly used for automatic detection of the edge curve formed after the super-large shearing machine is cut, so as to realize the detection of the shearing edge of the plate. The amount of deformation is automatically compensated.
