An industry-oriented workflow for noise reduction in handheld 3D scanning: A case study in automated dimensional inspection

Abstract Reliable dimensional inspection with handheld 3D scanners is frequently affected by unstable environmental conditions, reflective surfaces, and operator-dependent variability. This study introduces a practical, industry-oriented workflow designed to minimize noise during both acquisition and post-processing. The approach combines controlled lighting and temperature management, surface preparation using matte spray coatings, and optimized scanning trajectories to enhance data capture sta
