Machine Vision Inspection Techniques Guide

This document describes four machine vision inspection techniques: three-dimensional inspection using a laser line (light-sectioning method), detecting surface warpage with stripe pattern illumination, three-surface inspection using prisms, and color-component exclusion using infrared illumination. Each technique outlines specific configurations of lighting, cameras, and image analysis tools (such as Trend Edge and Stain tools) to detect defects like dents, warpage, stains, and lead positions on targets.
