Online web imaging solution - MTS concept and WIS (Web Imaging Solution)

Abstract

This paper describes the features and merits given by Yokogawa WIS and WIS roles in the MTS (Machine Technology Solution). The system configuration of WIS is simple and keeps higher performance regardless of increase of cameras. WIS is good to maintain and reduces maintenance time and cost. Also WIS performs the automatic intensity control of light source and enables to extend a life span of light source. WIS has easy operator interface (defect map) for human feeling to accept. WIS provides various formation images such as displaying a reference beside of live formation, both sheet edge one. Regarding defects to be difficult to detect, WIS can detect water drops by transmission and lower contrast defects such as wrinkles, weak spots by SDI (Subtle Defect Image) technology. We introduce the overview of the advanced Auto Classifier which can classify automatically every kind of defect by applying neural network technology. Auto Classifier can create setting values and attributes to be needed to classify defects. WIS is easy to expand system and able to interface with our MTS elements such as ABS, MAS, QCS and so on.
