Three‐dimensional (3D) selfie services, one of the major 3D printing services, print 3D models of an individual's face via scanning. However, most of these services require expensive full‐color supporting 3D printers. The high cost of such printers poses a challenge in launching a variety of 3D printing application services. This paper presents a stencil‐based 3D facial relief creation method employing a low‐cost RGBD sensor and a 3D printer. Stencil‐based 3D facial relief is an artwork in which some parts are holes, similar to that in a stencil, and other parts stand out, as in a relief. The proposed method creates a new type of relief by combining the existing stencil techniques and relief techniques. As a result, the 3D printed product resembles a two‐colored object rather than a one‐colored object even when a monochrome 3D printer is used. Unlike existing personalization‐based 3D printing services, the proposed method enables the printing and delivery of products to customers in a short period of time. Experimental results reveal that, compared to existing 3D selfie products printed by monochrome 3D printers, our products have a higher degree of similarity and are more profitable.

从RGBD图像创建基于模板的3D面部浮雕以进行3D打印

三维（3D）自拍服务是主要的3D打印服务之一，可通过扫描来打印个人面部的3D模型。但是，这些服务大多数都需要昂贵的全彩支持3D打印机。这种打印机的高成本对启动各种3D打印应用程序服务构成了挑战。本文介绍了一种使用低成本RGBD传感器和3D打印机的基于模板的3D面部浮雕创建方法。基于模板的3D面部浮雕是一种艺术品，其中的某些部分是孔，类似于模板中的孔，而其他部分则与浮雕中一样突出。通过结合现有的模板技术和浮雕技术，提出的方法创建了一种新型的浮雕。结果，即使使用单色3D打印机，3D打印产品也类似于两种颜色的对象，而不是一种单色的对象。与现有的基于个性化的3D打印服务不同，该方法可以在短时间内将产品打印并交付给客户。实验结果表明，与由单色3D打印机打印的现有3D自拍产品相比，我们的产品具有更高的相似度，并且利润更高。
