Abstract

Among various three-dimensional (3D) scanning anthropometric surveys, the inconsistent arm postures for scanning may lead to incompatible measurement results. Therefore, this study aims to investigate the effect of arm posture on the scan-derived measurements. The two arm postures in concern are the one with palms facing inward and the one with palms facing backward. The experimental results reveal that the two postures do not differ from each other in obtaining the scan-derived measurements for most body dimensions except for those related to the upper torso. Besides, the scan-derived measurements can be more precise between the two postures than the manual measurements. Further, it was found that being scanned with palms facing backward can contribute to the smaller difference between the scan-derived measurements and the manual measurements and the better image quality. Overall, the arm posture with palms facing backward is considered as the preferred posture for 3D whole body scanning.

摘要

在各种三维（3D）扫描人体测量调查中，扫描时手臂姿势的不一致可能导致测量结果不一致。因此，本研究旨在探讨手臂姿势对扫描测量值的影响。关注的两种手臂姿势是掌心朝内和掌心朝后的姿势。实验结果表明，除了与上半身有关的那些尺寸外，这两种姿势在获得大多数身体尺寸的扫描测量值方面没有区别。此外，与手动测量相比，这两种姿势下的扫描测量值更加精确。此外，研究还发现，掌心向后扫描可以减少扫描测量值与手动测量值之间的差异，并且获得更好的图像质量。总的来说，掌心向后的手臂姿势被认为是 3D 全身扫描的首选姿势。
