Pro/E曲面造型技术的牙齿三维模型重建

Tooth 3D solid reconstruction technology based on Pro/E software

提出基于曲面造型功能的三维模型重建方法,并应用Pro/E软件实现口腔牙齿的CT(Computed Tomography)影像的三维实体重建,生成可编辑的牙齿三维实体模型。该方法综合使用Photoshop、AutoCAD、Pro/E图形图像处理软件,主要实现过程为:通过螺旋CT获取断层图像;用Photoshop去除噪点,提取断层轮廓线;用AutoCAD样条拟合断层矢量图;用Pro/E曲面造型技术形成三维实体模型的重建。该模型与螺旋CT三维重建影像比较,具有更好的几何相似性与还原性。

Proposes a 3D tooth model reconstruction method based on surface modeling function of Pro/E software. With applying the Pro/E software,the method achieves the 3D tooth model reconstruction through CT image and successfully creates a 3D tooth model that can be edited. The method applies three image processing software like Photoshop, AutoCAD and Pro/E. It first gets the section image through spiral CT, and then modifies with Photoshop to eliminate the noises, and then taking the profile lines of the section ;later, creating vector graph with AutoCAD;finally, imitating the 3D tooth model with the surface modeling function of the Pro/E software. Comparing with the 3D reconstruction image from spiral CT ,its model has better similarity and reducibility
