Abstract
In this paper, a teeth correction 3-D data modeling technology based on the basis of optical measurement is proposed. Using structured light measurement, the STL data of the teeth plaster model are obtained. Based on STL data, the topological relationship model of vertices and planes is constructed. The data of single tooth is separated with separation algorithm, and using matrix transform, geometrical transformation of teeth model is realized. Then, after establishing frame curves, the 3-D solid modeling of corrected tooth socket is constructed. At last, using the SLA technology, the colophony model of the remedying device is produced.
