The motivation is to replace invasive and time-intensive point-based measurements that slow takt time and impede automation while tight positional tolerances must be met. Normalized criteria (spatial resolution, trueness, precision, environmental robustness, throughput, operating envelope, and lifecycle cost) are scored using a shared processing pipeline to ensure fair comparison. The Airbus crown module serves as the use case, prioritizing reliable detection of 12-24 mm bores at 1.0-1.5 m working distance under realistic interior conditions and takt constraints. Structured light, LiDAR, and stereo vision are assessed under ISO 5725 accuracy concepts, with structured light cameras attaining the highest overall utility (0.85) over LiDAR (0.76) and stereo vision (0.74) due to finer spatial resolution and strong trueness and precision at meter scale. Sensitivity analysis confirms ranking stability across broad weight variations.en2212-8271Procedia CIRP2026185190Elsevierhttps://creativecommons.org/licenses/by/4.0/3D MeasurementAssembly Assistance SystemsProductdesignTolerancesUtility AnalysisTechnology::629: Other Branches::629.1: Aviation::629.13: Aviation EngineeringSystematic selection and industrial evaluation of 3D measurement methods for positional tolerance compensation in final assembly linesConference Paper10.1016/j.procir.2026.05.24510.15480/882.17844
