摘要
目的应用三维光学扫描及快速成形技术制作人面部软组织三维树脂模型,为研制颌面赝复体计算机辅助设计(computer aided design,CAD)与计算机辅助制作(computer aidedmanufacture,CAM)系统奠定基础。方法采用自主研发的三维光学测量系统对志愿者左右侧面部分别进行扫描,通过 Surfcaq 软件对图像数据进行转换,获得完整的点云数据。以鼻尖点、颏下点、眼眶外侧点作为标定点,在 Geomagic studio 软件中对点云数据进行拼接、拟合,三维重建面部软组织。将三维重建图像导人 Magics RP 软件,进行三角化,并生成2 mm 的厚度,利用快速成形设备制作面部软组织三维树脂模型。结果获得了志愿者面部软组织的三维重建图像,并经快速成形制作出面部软组织三维树脂模型。结论利用三维光学扫描可进行人面部软组织三维重建,利用快速成形技术制作面部软组织三维树脂模型切实可行。
Objective To evaluate application of three-dimensional reconstruction of the facial soft tissue by use of light three-dimensional scanning system and rapid prototyping and to lay a foundation for developing the computer aided design （ CAD ） and computer aided manufacture （ CAM ） system of the maxillofacial defect rehabilitation. Methods The left and right facial profiles of a volunteer were scanned with the light three-dimensional scanning system that was a self-developed one. The complete point and cloud data were obtained by transforming the image data with the Surfcaq software, Then three-dimensional reconstruction was done via transforming the point and cloud data to Geomagic studio 7.0 . The final three-dimensional reconstruction was achieved by way of putting the point and cloud data together with apex nasi, external point of the orbit, menton as the mark points. The image was imported into Magics RP to triangulate and created in the thickness of 2 mm, The three-dimensional resin model was fabricated by fused deposition modeling （FDM）, Results The three-dimensional image of the facial soft tissue of the volunteer was achieved, The three-dimensional resin model of the facial soft tissue of the volunteer was also obtained, Conclusions Light three-dimensional scanning system was feasible for three-dimensional reconstruction.
