The Validation of Hand Anthropometry Using 3D Laser Scan

Abstract:

Hands are the most frequently moving segments of human body. Hand tools require fitness to hand dimensions of users. Hand anthropometry has promoted the measuring from tapes, calipers, or Martin-type anthropolometers to 3D laser scan. Nevertheless, all measurements of hands were under standard postures. Prediction models for functional posture dimensions were developed to compensate for the lack of this kind of databases. The project is planned to measure 3D surface range data under six different hand postures of two hands of each 600 subjects by a laser scan system. The primary validation for this scan system is presented in this paper. The resulted precision was 3.6% and accuracy was 2.2% and 5.3% for standard and functional posture, respectively.
