Abstract: At UNITEC Tegucigalpa, it was observed that, during anthropometry laboratory practices, body measurements were obtained from the subjects measured using traditional methods, where the measurers took the measurements in various ways. This variability caused fatigue in both the students being measured and the measurers, resulting in delays in obtaining results. Consequently, these results could have some degree of alteration, which was not conducive to the classroom activity. The objective was to analyze improvements in the methodology for taking anthropometric measurements through alternative measurement methods, with the participation of 14 students from the Methods Engineering I class. It was found that the photogrammetry method offered greater reliability (AE = -0.40 cm) compared to the 3D scanning method (AE = +4.19 cm). The photogrammetry method had the highest percentage of activity by the measuring student, reaching 100%, and reduced the time by 32.16% (average percentage relative error with AE = -8.13 min) compared to the traditional method. On the other hand, the 3D scanning method resulted in a greater idle time for the measurer, accounting for 78.82% (7.79 minutes) of the total time. The main contribution of this research was to analyze the advantages and disadvantages in terms of time, accuracy, cost and handling of the capturing technologies when using both alternative methods in a university anthropometric practice scenario.
