Evaluating the Accuracy of Low-Cost Scanning Technology to Reconstruct Full-Body Morphology

Abstract

Accurate reconstruction of full-body morphology is critical in many fields. This study evaluated the accuracy of 3 low-cost scanning technologies for capturing 3D body surface geometry: LiDAR sensors, ZOZOSUIT2, and ZOZO_v3. Participants were scanned using laser scan, LiDAR, and ZOZO’s methods. The scans were fitted to STAR models for comparison. The low-cost technologies captured 3D body surface geometry in an adult population, with RMSE values of 11.33 (4.39) mm (LiDAR), 7.13 (1.65) mm (ZOZOSUIT2), and 6.61 (1.93) mm (ZOZO_v3). All 3 methods demonstrated no gender bias in reconstruction accuracy.
