Abstract:
Objective:To provide data support to the anthropometry for medical selection of the Air Force flying cadets by investigating the accuracy of the measurement based on three-dimensional scanning technology.Methods:Using cluster sampling, 987 participants were selected for Air Force medical selection physical examination in 2022. The Air Force recruitment medical selection defined data (body height, sitting height, chest circumference, upper extremity length and lower extremity length) were measured manually and automatically by 3D CaMega which was based on three-dimensional scanning technology. The results of both measurements were compared. The accuracy of auto measurement was calculated against the manual measure result. The body height, sitting height, upper and lower limb lengths were respectively verified by 2 measurements upon selection criteria, and the concordance rate was calculated. The time spent on manual and auto measurements was compared in 107 students who were measured in the first examination day.Results:The body height, sitting height and chest circumference that measured by 3D CaMega were higher than those measured manually ( t=13.07, 14.45, 42.49, all P<0.001), but the lengths of upper and lower limbs were shorter ( t=39.66, 5.23, both P<0.001). In terms of the degree of difference, the variance of chest circumference between the 2 measurement methods was the greatest and followed by sitting height, lower limb length and upper limb length. Body heights showed the smallest difference. Compared with the manual measurement, the accuracy rates of auto measurement of body height, sitting height and upper and lower limb lengths were above 97%. The concordance rate of both measurements was above 98%. The automatic measurement by 3D CaMega took longer time ( t=29.39, P<0.001), compared with the manual measurement. Conclusions:Three-dimensional scanning technology can meet the demands of anthropometry for medical selection of the Air Force flying cadets and shows good application prospect in future.
