Reliability Evaluation of 3D Body Surface Measurement System for Pelvic Displacement Diagnosis

Abstract

In this study, the reliability of the 3D body surface measurement system was evaluated through the repeatability analysis of the depth feature when the four postures were repeatedly measured three times. Depth features were defined as the difference in depth values of 18 symmetrical left and right points by dividing the body surface of the lumbar spine and pelvis by 5x5 grid regions. Each depth value was calculated by averaging the depth values of 3D points included in the range of 12.5%, 25.0%, 37.5%, and
