Multi-Sensor 3D Scanner For Postural Analysis
Abstract
Posture is usually defined as the relative position of body elements. The ideal posture is the one where the articulations are under a minimum amount of stress but it is never achieved due to individual factors. It is im- portant to measure this lack of balance to minimize its effects in long term. This paper presents the creation of a multifunctional 3D scanner for posture analysis that allows the measurement of distances and angles between anatomic points of the body in a semi-automatic way, adding applications that only 3D information can aggregate, like the measurement of body volume to calculate the subject’s body fat percentage and body part perimeters. This equipment was built us- ing 2 RGB-D sensors combined with the reconstruction library ReconstructMe and the MeshLab software, creating an easy-to-use and interactive system. The developed application was used in postural analysis tests of a mannequin fol- lowing the SAPO protocol of posture assessment and compared to the SAPO software, indicating good correspondence between the methods.
