摘　　要：目的探讨三维人脸虚拟整形系统临床应用效果。方法对2017年6月至2018年5月就诊于湘雅医院的行面部整形手术的80例患者(男28例,女52例,年龄18-40岁)连续采集多帧包含人脸的二维人体彩色图像和三维人体点云数据,对采集数据进行人脸检测,对检测到的多帧三维人脸点云进行超分辨率融合,利用融合后的三维人脸点云数据建立三维人脸模型,采用纹理映射技术实现二维彩色图像到三维人脸模型的映射。最后由患者和医生交互式地在三维人脸模型上实施虚拟手术,获取满意的目标三维人脸模型。通过对比虚拟手术前、后三维人脸模型的变化,获取患者面部的整形手术中需调整的数据,并根据数据对80例患者完成面部整形手术。于术后1年重建患者三维人脸模型,与虚拟手术后模型对比,评估整形手术的效果。结果80例患者采用上述方法进行整形手术,其中内眦开大术6例、外眦开大术9例、隆鼻术20例、唇部修薄术25例、全面部脂肪填充20例。术后1年,80例患者均对整形结果表示满意。结论三维人脸虚拟整形系统使得整形设计过程具有个性化、定量化、数字化特点,使患者对预后效果预先有了比较好的了解,便于医、患之间的交流,可减少不必要的医疗纠纷。Objective To explore the clinical application of three・dimensional face virtual plasticsystem. Methods 80 patients ( 28 males and 52 females, aged 18-40 years) who underwent facial plasticsurgery in Xiangya Hospital were sampled with two-dimensional human color images and three-dimensionalhuman point cloud data continuously. Face detection was performed on the collected data, and superresolutionfusion was performed on the detected three-dimensional human point clouds. A three-dimensionalface model was built using the fused three-dimensional face point cloud data, and the texture mappingtechnology was used to realize the mapping from two-dimensional color image to three-dimensional facemodel. Finally, patients and doctors perform virtual surgery on the three-dimensional face modelinteractively to obtain satisfactory target three-dimensional face model. By comparing the changes of threedimensionalface model before and after virtual surgery, the data to be adjusted in the facial plastic surgery were obtained, and 80 patients received facial plastic surgery according to the data. The three-dimensionalface model of patients was reconstructed one year after operation, and then compared with the model ofvirtual surgery to evaluate the effect of plastic surgery. Results 80 patients underwent plastic surgery withthe above method, including 6 cases of medial canthus, 9 cases of lateral canthus, 20 cases of rhinoplasty,25 cases of lip thinning, and 20 cases of facial fat grafting. One year after operation, 80 patients weresatisfied with the result of plastic surgery. Conclusions The three-dimensional virtual facial plastic systemmakes the process of plastic design individualized , quantified and digitized. It enables patients to have abetter understanding of prognosis in advance, facilitating the communication between doctors and patients,and reducing unnecessary medical disputes.
