The function of machine vision in industrial automation is to enable real-time inspection, analysis, and control of manufacturing processes through visual information. Using cameras and image processing software, machine vision systems can identify defects, guide robotic tasks, and monitor production quality. This technology enhances operational efficiency by improving precision, reducing human error, and speeding up quality assurance processes. By automating visual inspections, industries can achieve consistent output quality, leading to higher productivity and decreased production costs while ensuring compliance with safety and regulatory standards.
