Application and Research of Machine Vision Technology in White Body Adhesive Defect Detection and Automatic Repair
In traditional production processes,adhesive defects are manually inspected,which is inefficient,inaccurate,and influenced by human responsibility and subjective experience.In recent years,an increasing number of automotive companies have adopted machine vision technology for defect detection.This paper discusses a specific adhesive coating process in the white body production process.By using a 2D array camera and employing methods such as image seg-mentation,object extraction,skeletonization,and B-spline curve fitting,the adhesive area and path are analyzed and fitted.Additionally,camera calibration and hand-eye calibration are performed on the vision system.This allows the automatic re-application and repair of adhesive defects,such as adhesive breakage and under-application,guided by a robotic arm.
