| Summary: | Anthropometric measurements using conventional tools have been extensively used and considered as the gold standard for generating accurate and reliable anthropometric data on the human body. With the advancement of three-dimensional imaging technology, various types of 3D scanners have the potential to be used as digital measuring tools in anthropometric measurements. Handheld 3D scanners can be used as a relatively affordable alternative, but they still lack reliable and proven methods for producing valid anthropometric measurement data. Therefore, in this final project, a method for anthropometric measurement using a handheld 3D scanner with tested validity has been developed.
The anthropometric measurement methods developed include procedures in conditioning measurement subject’s body position, breathing cycle, muscle tension, and clothing, conditioning the environment, the motion and distance of the handheld 3D scanner in scanning the measurement subject, as well as anthropometric measurements on a three-dimensional model using Blender and MATLAB software.. The developed digital anthropometric measurement method was successfully applied to 10 measurement subjects across 23 different body dimensions with 5 repetitions, resulting in 1150 data points of anthropometric measurements.
An agreement analysis between conventional and digital anthropometric measurement methods was conducted to test the validity of the digital anthropometric measurement method. A good agreement between the methods was found, with mean errors (???? ??) of 0,4 [?1,3; 2,1], 0,8 [0,4; 1,2], and 1,8 [0,9; 2,7] centimeters at a 95% confidence interval, average intraclass correlation coefficient for agreement type (???????? (???? , 1) ????????????) of 0,79 [0,31 ; 0,95 ], 0,79 [0,20 ; 0,95 ], and 0,83 [0,31 ; 0,96 ] at a 95% confidence interval, and average p-values from paired t-tests of 0,50 , 0,35 , and 0,48 for height, length, and circumference dimensions, respectively. Based on the results of the agreement analysis, it can be concluded that the developed digital anthropometric measurement method has been validated.
