VL Series 3D Scanner Comparative Measurement Guide

This document describes the VL Series 3D scanner and its comparative measurement function, which overlays scan data of actual objects onto 3D CAD drawing data (STEP, IGES) to visualize shape differences with color. It highlights the challenges of traditional shape measurement methods, such as time consumption and inability to compare free-form geometries, and positions the VL Series as a solution for quickly identifying deviations like protrusions and recesses.
