自动获取牙齿等表面全场形状参数的图像处理过程

The An Image Processing Method For Automatically Obtaining The 3D Shape Data of Tooth Whole Surface

为了自动地实现无接触测量牙齿等物体表面形状的全场参数，本文提出了从被物体表面形状干扰的栅线图像信号中提取三维形状信息的方法，结合成熟的计算机图像处理技术，该方法可构成精度、量程、自动化程度方面都具有较强适应性的测量系统。讨论了该方法的原理、系统构成，并给出了一牙齿模型的测量实例。

In this paper, a method by which 3D shape information of tooth surface was obtained from images of the grating lines modulated by that surface, Using technique of computer image processing, the measurement system basing the method is suitable in accuracy,range circumstances and automaticity. An example is given and discussed.
