Materials manufactured in a continuous roll or sheet, such as paper, textiles, film, foil, plastics, metals, glass or coatings, are most effectively inspected using machine vision line scan systems. These systems are designed to detect and identify defects in webs or objects moving at high speed. Line scan systems enable a complete surface inspection by building a continuous image, one row of pixels at a time, in the direction of the web’s motion. Image capture continues as long as the camera and web are operating. In addition to the unlimited pixels enabled by continuous motion, line scan imaging delivers crisp, smear-free images at high speeds, with higher dynamic range, greater processing efficiency and a much lower cost per pixel than traditional area scan systems.
