Abstract

This Paper introduces a self—adaptive and training concepts to improve the speed of slow visual inspection system to near one order of magnitude. In this scheme, the system is designed to work in three modes : Mode I (fast inspecti on) ,Mode I I (slow inspecti on) and Mode I I I . The first two modes automatical ly shi ft to each other depending on the condi tion of rol 1 er surface . Mode I I I is for automatic optimal binary threshold selection of defect image, in which a bifurcated searching algorithm is employed. At last, an algorithm for dot group pattern recognition of roller defects is discussed.
