摘要
本文提出了一种基于Borland c++ Builder®和OpenGL的三维数字牙齿模型的计算机分割算法。目的是将该算法应用于三维正畸诊疗软件包中。该方法包括以下5个主要步骤。首先利用三维扫描仪生成STL格式的数字牙体模型,计算牙合平面;其次,对模型的拱形进行了近似。第三,构建牙模三维全景系统。第四步,将三维全景图像转换为二维系统,寻找切点对单个牙齿进行分割,最后将二维图像转换回三维系统,在切点处创建用于将牙齿分成不同颜色的垂直面。结果表明,该算法可以实现对三维数字牙模型的分割,并可应用于正畸诊疗软件包中。
This paper presents the computerized segmentation algorithm on the 3D digital dental model for separating individual tooth using Borland C++ Builder® and OpenGL. The purpose is to apply the algorithm in the 3D orthodontic diagnosis and treatment software package. The method consists of 5 main steps as follows. First the digital dental model is produced by 3D scanner in STL format and the occlusal plane is calculated. Second the arch form of the model is approximated. Third the panoramic of the dental cast in 3D system is constructed. Fourth, the 3D-panoramic is converted to 2D system to find the cutting points for segmentation of individual tooth, and finally the 2D image is converted back to 3D system for creating the vertical plane for separating teeth into difference colors at the cutting points. The result has shown that the 3D digital dental model can be segmented for separating individual tooth, and the algorithm is ready to apply in orthodontic diagnosis and treatment software package.
