The specific objectives of the project are:
- To establish the traceability of existing and newly developed industrial MVSs used in (i) dimensional quality, (ii) surface quality, (iii) structural quality, and (iv) operational quality including the development of appropriate material standards with canonical and complex shapes, calibration strategies, traceable identification of MVSs parameters, and uncertainty budgets (target uncertainty 1 μm – 150 μm dependent on MVS application area). More details on WP1
- To develop Digital Twins (DTs) of selected and newly developed MVSs through physical modelling and/or computational modelling, and to then (i) predict their responses in analysing systematic errors, and to (ii) obtain an optimal measurement strategy in the shortest cycle time. In addition, to develop approaches for the validation of these DTs that include robust methods (e.g., softgauges), and statistical procedures for the assessment of differences between measurements of calibrated standards and corresponding data from their virtual counterparts. More details on WP2
- To investigate and evaluate novel methods and algorithms for dense image matching (coarse and fine image alignment) of multiple recorded images using ‘softgauges’ (reference data). The algorithms will use external knowledge (e.g. physical markers, contactless tracking systems, precise positioning systems, intrinsic features of the scene) and filtering processes will be considered. Additionally, robust algorithms will be developed and validated for analysing the full 3D reconstruction and uncertainty budgets compiled. More details on WP3
- To investigate the outputs and outcomes developed in this project while addressing industrial use cases related to dimensional, structural, surface and operational qualities. In addition, the performance of selected traceable MVSs for industrial applications will be tested on industrial freeform artefacts in a round robin comparison exercise. Based on measurement results, training material and a GPG for T-MVS performance assessments (e.g. dimensional, structural, surface and operational qualities) will be produced. More details on WP4
- To facilitate the take up of the technology, good practice guides and measurement infrastructure developed in the project by the EMNs MathMet, TraceLabMed, AdvManu, the measurement supply chain, standards developing organisations (ISO/TC213 and ASTM), and end users (manufacturers from the automotive, food, pharmaceutical, etc. sectors). This includes demonstrations of the practical application of the developed technology in multiple industrial applications (e.g. automotive, aeronautic, pharmaceutical). More detail on WP5
