The three-dimensional mathematical modelling is a very efficient tool for the volumetric objects modelling and analysis. The paper presents the application of these methods in orthodontics as it is able to replace standard plaster casts by images of scanned objects.
Geometric morphometrics represents a new ap-proach to multi-dimensional data modelling both in medicine and engineering. Data acqusition enabling to transform physical model to its three-dimensional mathematical representation include the use of 3D scanners, multi-camera sys-tems but also special methods based on multi-pictures composition.
The paper is devoted to one of these methods, calibration of the three-dimensional math-ematical model and possibilities of resulting surface visualization. The goal of such a modelling is in objects detection and classification, shape determination and evaluation of important measures.
The paper describes the technique of data acquisition and export of resulting data into the MATLAB environment. The proposed algorithm is devoted to the three-dimensional data interpolation and selection of specific object components for their further analysis and pro-cessing.
The graphical user interface is proposed to simplify the whole process and to present the surface plot of the dental arch.
