A 3D head model fitting method using chinese head anthropometric data

Abstract

The rapid growth of the Chinese consumer market has created a demand for new Chinese fit wearable products. The industry requires accurate digital data on Chinese head and facial shapes to develop new consumer products. 3D head models that express the dimension of Chinese head anthropometry are of great importance in various product design processes. Previous 3D statistical models were fitted mostly using dimensional frames made by head and facial landmarks that cannot adequately demonstrate the complex facial geometry. This paper proposed a 3D head fitting method for the 5th, 25th, 50th, 75th and 95th percentiles using a progressive scanning algorithm based on differential approximation. The high-precision point cloud data obtained were transformed into mesh models, and the facial details were integrated and improved by 3D facial feature frameworks and artistic digital sculpting. The 3D digital models and 3D printing models with different percentiles constructed in this research can be utilized as design-aided tools for physiological comfort optimization in wearable products design and other ergonomic evaluation procedures.
