An Isomorphic Polygon Model for Describing Human Body Shape

A novel polygon model describing human body shape is developed. Firstly, a method of expressing an arbitrary point on a polygon mesh using the UV plane (9), (10) is proposed. An isomorphic feature of the model enables us to fit the polygon model to three-dimensional (3D) measurements by means of the least square method. Secondly, we efficiently allocate polygon vertices to trunk shape based on multiple sets of 3D measurements of Japanese women. The finally, derived generic model consists of 1,087 vertices and can reconstruct the original shape with the average error of 1.19 mm. This accuracy is sufficient for practical use.
