Applications of colorimetry in machine visions for checking electronic components and quality of pulp paper

摘要

Application of colorimetry in color identification for checking electronic components and quality of pulp paper is proposed. Inspection of missing electronic components during the assembly of the printed circuit board (PCB) and dirty portions on pulp paper can be done by an analysis of color image. This method helps to improve the image-processing speed. Additionally, the inspection accuracy can be attained by the use of color isodiscrimination contour criterion.
