On Application of Industrial Robot Based on Machine Vision in Recognition, Instruction and Assembly

Abstract

It is of great significance to apply machine vision technology into developing manufacturing industries. In this project, LabVIEW VDM was used in the design of online working system of based-on machine vision mechanical products, including intelligent identification, localization, guidance and assembly. The target objects of original images were extracted and altered through morphological opening-andclosing objectives and automatic median processing before accurately localize the target area through thickening and thinning; at last, randomized Hough transform was used to rebuild the shape to separate the overlapping round targets. Results showed that this system is reliable and accurate, the accuracy of screw installation reaching 0.01mm, that simultaneous multi-functional operation is possible in industrial robots, and that the overall-controlling software designed as a standardized protocol that can accept different industrial robots can improve the working efficiency and intelligence degree of automatic line.
