Digital image processing digital using Labview software for autonomous inspecting and label-sorting machines in packing process

Abstract

Nowadays, in industrial factories, image processing technology and its
application are gradually replacing manual inspecting, and also being
constantly developed to reduce potential risks in manufacturing process,
as well as to improve productivity and performance. With its advantages,
image processing can be applicable in many different fields such as food
industry, textile industry, and electronic industry.
The article describes an application using Labview software to inspect
label by digital camera, as well as to sort faulty labels including no
printing, faint printing and broken labels. The program of the application
can recognize the both characters and barcode on label.
We designed and built an automatic system for inspecting and sorting
label using Labview software. Clamping mechanism using single cylinder
robot is controlled by PLC Delta DVP-SV and monitored by HMI screen.
