Virtual restoration method for interactive broken relics

Abstract

The invention relates to a virtual restoration method for interactive broken relics. The method comprises the steps that (1) relic piece data acquisition and classification are carried out; (2) three-dimensional model interaction based on Wiimote is carried out; (3) complementary splicing and virtual restoration of relic pieces are carried out; (4) relic virtual restoration based on template matching is carried out; and (5) relic entity restoration based on three-dimensional printing is carried out. According to the invention, an MSME three shaft accelerometer, a gyroscope and an infrared induction strip are used to realize interaction control of relic models; real-time calibration is carried out on MSME displacement and attitude 6 freedom degree information; the limitation of poor interaction control accuracy caused by gravity acceleration and poor MEMS sensitivity is overcome; the relic piece virtual restoration problems of two conditions that semantic relevance exists while a complementary matching relationship is inconsistent, and a complementary relationship is consistent while strict edge matching cannot be realized are solved; and rapid relic entity restoration can be completed with a three-dimensional printer.

Description

technical field [0001] The invention relates to an interactive virtual restoration method for broken cultural relics in the technical field of digital restoration of cultural relics, in particular to an interactive virtual restoration method and a physical restoration method for broken cultural relics. Background technique [0002] After several years of natural weathering, erosion and man-made destruction, most of the unearthed ancient cultural relics have become incomplete. After archaeologists excavate these broken cultural relics, they need to sort, clean, splicing, bonding, manual restoration and other processes to restore the original appearance of the cultural relics. The main problems to be solved by the staff during the actual repair process are: (1) How to determine the adjacency of fragments, which is essentially a mathematical problem NP-complete problem, and the worst method needs to be matched with each fragment; (2) How to determine the splicing relationship ...
