EVALUATING THE VIABILITY OF PHOTOGRAMMETRY AS AN ALTERNATIVE TO STRUCTURED LIGHT SCANNING IN WOODWORKING SCULPTURE DIGITIZATION

Abstract


The study explores the strengths and limitations of photogrammetry and structured light scanning methods in generating detailed 3D representations of handcrafted and machined wooden components. A high-quality woodworking part with intricate surfaces and fine detailing served as the test object, scanned using a Creaform Go!SCAN 50 with VXelements software, and, separately, digitized through a photogrammetric workflow. Both resulting 3D models were aligned and compared against each other, with the structured light scan serving as the reference due to its higher expected precision. The comparison evaluated dimensional accuracy, surface detail retention, and geometric fidelity. The study examines the advantages and drawbacks of each method with respect to precision, usability, processing time, and their applicability within woodworking design, reproduction, and quality assurance workflows. The research aim is to evaluate whether photogrammetry can serve as a cost-effective substitute for structured light scanning in woodworking contexts, particularly in applications involving custom furniture making, intricate joinery, and the restoration of heritage artifacts.
