Abstract

The lighting condition is critical in the anthropometric scanning process. Optimal lighting condition affects the time and precision. The current study sought to determine the optimal light for measuring the static anthropometric dimensions of feet and hands based on the precision, trueness, and efficiency of EinScan Pro 2X Plus. Three conditions of the scanning process were Light Zero Light/ZL: 5–50 lux, Normal Light/NL: 50–100 lux, and Room Light/RL: 100–200 lux. The data collected and analyzed were 3D model mesh data (point clouds), which were then processed using CAD software for deviation analysis. The precision variable was computed using the pooled standard deviation ((Formula presented.)) value. The Absolute Error (AE) and Absolute Percentage Error (APE) were used to calculate the trueness variable. The efficiency aspect was measured based on the average value of measurement time. The optimal lighting condition was ZL, which was determined using a simple additive weighting method. The precision of the hand in (Formula presented.) value was 1.25 mm while the foot precision was 0.92 mm. The hand trueness in AE value was 1.73 ± 1.33, while the foot trueness was 1.34 ± 1.20 mm. The hand efficiency in time value was 273.94 s, and the foot efficiency were 272,94 s.
