Video Inspection Systems (VIS) are advanced optical measurement and defect detection solutions that combine machine vision technology with precision optics. These systems enable non-contact, high-speed, and high-accuracy inspection of components and materials across various industries. Modern VIS integrates AI-driven image processing algorithms, multi-spectral imaging, and automated analysis to ensure product quality, safety, and compliance with manufacturing standards.
