项目摘要

Recent investigations in laser scanning technology provide a potentially useful technique for accurate three-dimensional documentation of the face. In this study, linear and area measurements of the facial contour and facial units have been recorded in a variety of chosen facial postures using surface laser scanning combined with three-dimensional lighting techniques on healthy volunteers and patients with facial nerve paralysis.Three-dimensional surface measurement of the face was taken using a laser light scanner. Computer graphics lighting techniques were used to produce facial images constituted by highlights and shadows, which emboss facial contour and units. Then quantitative measurements of changes in facial angles and areas were made to analyze morphological changes of the face accompanying facial expression. Changes of angles and widths of the cheek and nasal units were found to be associated with dimensional changes imposed by the action of the underlying mimetic muscles. This system has potential value for both dynamic monitoring and evaluation of facial contour, units, and movement.

激光扫描技术的最新研究提供了一个潜在的有用的技术，准确的三维文件的脸。在这项研究中，面部轮廓和面部单位的线性和面积的测量已被记录在各种选择的面部姿势使用表面激光扫描结合三维照明技术对健康志愿者和面部神经麻痹患者。面部的三维表面测量使用激光扫描仪。利用计算机图形学光照技术生成由高光和阴影组成的人脸图像，反映人脸的轮廓和单元。然后定量测量面部角度和面积的变化，分析面部表情所伴随的面部形态变化。脸颊和鼻子单位的角度和宽度的变化被发现与尺寸的变化所施加的行动的基础模仿肌肉。该系统对面部轮廓、单元和运动的动态监测和评价具有潜在的应用价值。
