Abstract
Industry 4.0 requires sub-millimeter metrological precision for the geometric quality assurance of high-value industrial components, particularly in aviation and defense applications. This study presents a comparative evaluation of triangulation-based Handheld Laser Scanning (HLS) and phase-shift Terrestrial Laser Scanning (TLS) for micro-scale deformation detection. The Creaform HandySCAN Black (0.020 mm + 0.040 mm/m) and FARO Focus X330 (±2 mm) were benchmarked across four software platforms: CloudCompare (M3C2), PolyWorks, Geomagic Control X, and MeshLab. HLS achieved superior performance with an RMS deviation of 0.114866 mm, successfully identifying defects below 0.05 mm across 858 validated classes. TLS exhibited a noise floor of ±2 mm, confirming its limitations for component-level inspection. Statistical analysis demonstrated that the deviation data followed a Gaussian distribution (R² = 0.9834), indicating high measurement reliability and absence of systematic bias. The integration of HLS with the M3C2 algorithm enables high-fidelity Digital Twin generation and automated as-built vs. as-designed comparison workflows compliant with ISO 17025 requirements. The results demonstrate that HLS provides a fast, accurate, and industry-ready solution for Quality 4.0 applications in precision manufacturing.
