Stationary 3D whole-body scanners generally require 5 to 20 seconds of scanning time and cannot effective- ly detect armpit and crotch areas. Therefore, this study aimed to analyze the accuracy of a photogrammetric technique using a multi-camera system. First, dimensional accuracy was analyzed using a mannequin scan, comparing the differences between the scan-derived measurements and the direct measurements, with an al- lowable tolerance of ISO 20685-1:2018. Only 2 of 59 measurement items (ankle height and upper arm circum- ference, specifically) exceeded the ISO 20685-1:2018 criteria. When compared with the results of the eight sta- tionary whole-body scanners assessed by the literature, the photogrammetric technique was found to have the advantage of scanning the top of the head, armpit, and crotch areas clearly. Second, this study found the photo- grammetric technique is suitable for obtaining the body scans because it can minimize the perform scanning, re- sulting in a reduction of measurement errors due to breathing and uncontrolled movements. The error rate of the photogrammetry method was much lower than that of stationary 3D whole-body scanners.
