Paper Abstract

A position recognition system composed of a television camera, a special purpose real-time image processor, and a general purpose microcomputer is developed. This system realizes a local pattern matching technique utilizing several local portions of an image as standard patterns. New resampling hardware enables the standard patterns to be matched against local patterns with a basic 8x8 or 12x12 window size and its multiples. Also, a high reliability recognition scheme with redundant matching sequence is programmed in the microcomputer. These features provide a cost effective device with wide application possibility. This technique is beeing successfully applied to automatic assembly systems for almost all types of semiconductor products.
