3D-Scanning and Computer Reverse Engineering Technology to Preserve Inscriptions at Beihai Park
Special Issues Editor (Nottingham Tent University, United Kingdom (Great Britain))
The rapid development of computer reverse engineering and 3D scanning technologies has changed working practices in many different traditional industries, some in cultural heritage preservation. To document and preserve cultural heritage digitally is widely recognized and implemented today. However, seldom researchers have been involved in preserving stone inscriptions with these technologies. Stone rubbing is still a regular method of preserving calligraphies carvings but it can cause more damage to stone inscriptions. In this paper, we considered preserving fourteen important stone inscriptions of the YueGuLou, located at Beihai Park in Beijing. The YueGuLou has preserved more than 300 pieces of world-famous calligraphy from 135 calligraphers, and more than 500 stone inscriptions. These inscriptions are currently facing deformation, damage and even permanent loss due to physical and environmental factors. In our work here, the geometrical information is acquired with Breuckmann high-precision structured light 3D scanner for documentation and preservation purposes. Then we process with reverse engineering technology. Finally, some analysis is performed to demonstrate efficiency and accuracy advantages gained by this technology. The contribution of this research is: i) it verifies the feasibility of applying computer reverse engineering and 3D scanning technologies to stone inscriptions, and ii) it proves the superiority of efficiency and accuracy. This non-contact technology maximizes the importance of the subject while minimizing damage.
