[CN201610025701.X] Detection system and method for sheet metal shearing edge curve of super large plate shearing machine
[CN201610025701.X] A system and method for detecting shear edge curve of ultra-large plate shears Title: A system and method for detecting shear edge curve of ultra-large plate shears Application No.: CN201610025701.X Applicant: Jiangsu University Application Date: 2016-1-14 Patent Type: Application for the Invention The present invention discloses a system and method for detecting shear edge curve of ultra-large plate shears. Sheet shear edge curve detection system is mainly composed of optical imaging unit, image acquisition and processing unit and main control computer. The method for detecting the cutting edge curve of sheet metal of the present invention includes: firstly, real-time image acquisition of the cutting edge of sheet metal is carried out by using a CCD sensor and a lens installed on a super-large plate shearing machine under the cooperation of a strip light source; After the collected images are preprocessed, the images collected by adjacent industrial cameras are stitched, the edge of the image is detected after edge burrs are removed, and finally the coordinate axis and coordinate points are selected and the fitting technology are used, the actual processing curve of the sheared sheet is detected. The invention uses image real-time acquisition and image processing technology to detect the cutting edge curve of the plate, and the detection method can achieve higher detection accuracy and detection efficiency than the traditional detection method.
