Paper Abstract

Production and quality control managers are counting on automatic visual inspection to automate the last labor intensive factory operation. Image analysis, laser scanning and coherent optical processing have been used with varying degrees of success to solve particular production line inspection problems. In this paper we discuss four diverse applications: needle point inspection, fabric inspection, small part color verification and cotton trash measurement. Each of these problems is solved by a different technique. In particular, needle point inspection accomplished by diffraction pattern analysis, fabric inspection by coherent optical scanning, small part color verification by on-line spectrophotometry and cotton trash determination by coarse image sampling and processing. An overview of these four applications shows why the particular approach is chosen for each and illustrates the generic problem solved by each technique.
