Color image processing and vision system for an automated laser paint-stri

摘要

Abstract: Color image processing in machine vision systems has not gained general acceptance. Most machine vision systems use images that are shades of gray. The Laser Automated Decoating System (LADS) required a vision system which could discriminate between substrates of various colors and textures and paints ranging from semi-gloss grays to high gloss red, white and blue (Air Force Thunderbirds). The changing lighting levels produced by the pulsed CO$- 2$/ laser mandated a vision system that did not require a constant color temperature lighting for reliable image analysis. !6
