Back-Curve Fitting Model Based on 3D Anthropometry

This paper focuses on the back-curve of adult males measured by 3D anthropometric scanner. Males in group 170/88A were chosen as research samples to make the data collection easier. The back-curve was fitted by a polynomial function, and the cubic polynomial function was determined as a standard reference curve. The fitting function was then turned into a parameter function. The functional relationship between the chest depth, back length and back-curve length was obtained. This is so that the back-curve length can be zoomed through the proportional relationship, and the back-curve length from the back length and chest depth can be calculated when the sample is in the same group. This experiment showed that the error of the back-curve function fitted by our model is smaller than lcm, which was enough to satisfy the anthropometric measuring for clothing.
