Abstract

Anthropometrics is the study of the measurements of the human body. Initially, anthropometrics was used to help scientists and anthropologists understand physical variation among humans. Anthropometrics is a set of direct quantitative measurements of the external dimensions of the human body that can be used as a proxy for body composition. In general, they use tools such as calipers and measuring tapes to take measurements on the body, such as height, width and girth. However, nowadays, a device has been designed with which it can perform measurements in 3D without touch. Although a relatively new technique, advanced systems using three -dimensional (3D) scanners are now in use due to some limitations of conventional manual techniques for the collection of body measurements. The purpose of this study was to collect and compare the circumference parameter data on the hands of the respondents by using the method of Conventional and 3D Camera Anthropometry System (3D CAS) which Kinect camera and also using Statistical Analysis. This experiment was conducted on 30 male respondents. During the experiment, respondents will first be measured using tools such as calipers and anthropometers for conventional methods, after which CATIA and SOLIDDWORKS software is used for experimental measurements in 3D. As a result of the data, calculations, analysis and comparison between standard deviation, mean and percentile were performed. The use of computer-aided design (CAD) software, such as CATIA, can improve efficiency and accuracy when measuring the human body by reducing the need for manual labor and decreasing measurement time. This is because CAD software allows for the quick and accurate measurement of a 3D scanned image of the human body, which can be done in a fraction of the time it would take to manually measure the body using anthropometry tools. Additionally, the differences identified in this research can serve as a basis for future studies aimed at improving the measurement process. The final objective of this project is to study the best way to measure the respondent's hand during the 3D Camera Anthropometry System (3DCAS) and the results of the study shows that the use of Catia software is a better way for measuring the human body compared to using Solidworks software.The expected result for this thesis is, conventional methods have taken a long time to perform measurements while this CATIA software can facilitate to perform measurements on the human body.
