Abstract

A machine-vision-based intelligent automatic inspector for workpiece quality is presented. The mechanical structure and electric control system are illustrated in detail. An algorithm based on geometrical dimension measurement is proposed and an algorithm using the center of gravity of the workpiece is applied to locate the inspection area. According to the characteristics of workpiece, a reasonable and effective light and illumination system is designed and inspection software was developed on the platform of VC++ EDI. Experiments of the inspection performed on-line have proven the value of the proposed algorithms in automatic real-time inspection.
