目的 介绍三维扫描仪在非接触条件下采集面部软组织精确数据的方法 ,为临床整形提供标准的鼻眶窝三维测量数据。方法 应用三维激光扫描仪和Geomagic软件 ,采集 12例标准汉族人的颜面轮廓 ,并对鼻眶窝进行数据测量和分析。结果 通过三维激光扫描和逆向工程软件可以再现出面部形态有意义的任一角度的三维图像 ,且精确度达到 0 0 1mm ,实验初步确定了鼻眶窝最低点的三维定位 ,描述了鼻眶窝的三维形态特征。结论 此方法可以全面反映鼻眶窝与周围结构形态学上的相互关系 ,三维激光扫描是实现术前设计、手术模拟和术后效果评价的新途径
Objective To introduce the method of acquiring the accurate data of facial soft tissue under the condition of non-contact by three-dimensional scanner, and to provide the standard three-dimensional nasal and nasal fossa data for clinical plastic surgery. Methods Three-dimensional laser scanner and Geomagic software were used to collect the facial contour of 12 Han Chinese people. The data of nasal orbital fossa were measured and analyzed. Results 3D laser scanning and reverse engineering software could reconstruct three-dimensional images of any facial shape with a meaningful facial shape with an accuracy of 0 0 1mm. Experiments initially determined the three-dimensional localization of the lowest point of nasal orbital fossa, Three-dimensional morphological characteristics. Conclusion This method can comprehensively reflect the morphological relationship between the nasolabial fossa and the surrounding structures. 3D laser scanning is a new way to realize the preoperative design, surgical simulation and postoperative evaluation
