摘　　要：研究三维人脸模型孔洞修补问题。针对在建模过程中的佩戴饰物遮挡、建模角度等因素的影响,造成三维人脸模型孔洞的存在,人脸模型完整度、清晰度不高的问题。为解决上述问题,提出一种插值算法的三维人脸模型孔洞修补技术。根据已有的人脸模型三维信息,通过进行三角剖分,进行人脸面部轮廓的细化计算,增加孔洞处组成三维人脸的数据点的数目,进而对模型的孔洞处进行修复。实验结果表明,改进方法能够很好的恢复孔洞处三维人脸基本信息,能够大幅增加三维人脸模型的清晰度,有极大的应用价值。Research holes repairing technology of 3-d face models. Wearing accessories cause self-occlusion, which causes 3-d face models holes exist, and face models integrity and definition are not high. In this paper, a kind of interpolation algorithm based on the 3-d face models holes repairing technology was proposed . On the basis of the existing facial model of 3-d information and through triangulations, face facial contour refined calculation was carried out. By adding the number of pixels at the holes in which composed the 3-d face, the voids of model were repaired. Experimental results show that this method can recovery the holes in 3-d face very well and increase the definition of 3-d face model.
