Classification of Men’s Shoulder Shapes Based on Pyramid Method

This study conducted 3-dimensional grouping of shoulder shapes based on the feature points of the neck and shoulder by using 3-dimensional technologies. The study first extracted four feature points on the shoulders using the Pyramid method and formed a pyramid, and then projected them on tangent planes on the x-, y- and z-axis. This step was followed by an analysis of 45 measurements, including the angles and distances between the vertexes of the projected pyramid. The factor analysis of the measurements found out five major factors. The explanatory power of the factors was 92.29 percent.
