Application of 3D Printing Reconstruction Algorithm in Ancient Ceramic Restoration

Abstract

The study of the ancient ceramic is of great significance to the identification of authenticity, value recognition, cultural types, and dissemination channels of the ceramic. In this study, a series of technical problems such as ceramic contour extraction, image distortion correction, and nonlinear contour modeling for 3D printing of rotating body under complex background were solved and a restoration algorithm for the shape of ancient ceramics was proposed. Then, an accurate contour model is established by using the two-dimensional images of the rotating ancient ceramics to reconstruct the three-dimensional model of the ceramic shape. The experimental results show that the modeling algorithm for three-dimensional printed ceramics can accurately obtain the three-dimensional model of rotating ancient ceramics, which is of certain significance to explore a new direction of the research and development of three-dimensional printed ancient ceramics.

A Systematic Review on Virtual Reality Technology for Ancient Ceramic Restoration

“…Wu, H. and Ma Y. reconstructed a 3D model based on 2D images of rotating ancient ceramics through a new reconstruction algorithm. This new algorithm solved the problems of previous image processing methods, for instance, 2D image distortion, complex image background, and large varieties in image quality [26]. This method could yield a high-accuracy 3D model for 3D printing without a high-cost 3D scanner; however, the objects under reconstruction are restricted to rotating shape ceramic.…”

“…Under the realm of VR, virtual restoration technologies include deep learning, 3D printing, and 3D laser scanning, which are widely applied to cultural heritages such as stone sculptures, pottery sculptures, and massive architectures [6,[21][22][23][24]. Since ancient ceramic restoration is a branch of cultural relics restoration, these VR technologies are also applied to ceramic restoration [25][26][27], which is still relatively rare compared to other archaeological categories. In most cases of VR ancient ceramic restoration, the technologies applied mainly include 3D scanning, 3D modeling and 3D printing [28].…”
