RGB-D sensor application for static anthropometry measurement

Abstract

This study aimed to apply the RGB-D sensor for other alternative static anthropometric measurements. The RGB-D sensor that was used is Kinect Xbox 360 from Microsoft. The study was conducted by running the RGB-D sensor activation program so that it can detect static anthropometric measurements which include height, sitting height, leg length, knee length, hand length, forearm length, shoulder width and hip width. After the system run, the sensor captured objects that can be detected and then become input from the program and produce RGB data and depth (depth) and then processed again to get skeletal tracking. Skeletal tracking obtained if the sensor detects human presence. From the results of this skeletal tracking, the program can produce length data from each body part measured. Information processing results shown on the monitor screen in the form of units of length in centimeters (cm). The research results showed that from 110 anthropometric data that have been taken with this measurement system, the system showed the total absolute absolute error of 2.71%. Error for each antropometry measurement are height 2.53%, knee length 2.94%, foot length 2.97%, shoulder width 2.47%, hand length 2.16%, arm length 2.46%, hip width 2.67%, and sitting height 3.45%. From the results of regression analysis, the average correlation value between the actual value and the system value are 0.91 so that the results of the sensor measurements can be accepted. Can be concluded that the use of the Kinect sensor for anthropometric measurements can be used for anthropometric measurements.
