Abstract
According to the manufacturing process of the three-dimensional parametric hand model and the auxiliary tool manufactured by using the model, a three-dimensional scanner is used for scanning a three-dimensional hand model of a plurality of subjects. The three-dimensional model is built one by one according to the data. Dimensionality reduction is carried out to establish a regression relation between the data and the parameters after dimension reduction, forming 19 hand characteristic parameters and restoring the dimension. A three-dimensional hand model can then be established, and 19 hand characteristic parameters of the new subject can be measured. The measured hand characteristic parameters are inputted into a three-dimensional hand parametric model, and the three-dimensional parametric model approximating the handshape of the new subject can be generated. The auxiliary tool is drawn according to the three-dimensional hand model to obtain the auxiliary tool conforming to the handshape of the new subject.
