Digital rubbing method for stone inscription characters

Abstract

The invention discloses a digital rubbing method for stone inscription characters. According to the method, the stone inscription characters are subjected to photo taking in at least three different angles; the photography measuring technology is used for measuring the character three-dimensional dimensions in the photos; one photo with the character plane most similar to the image plane in the photos is selected for distortion correction, and the corrected images are subjected to character division; a real object is used for rubbing the background samples or rock image samples for rubbing background modeling; the divided characters are merged with the rubbing background; and the ink and rice paper diffusion seeping process is adopted for simulating the rubbing effect, and the digital rubbing manufacture is completed. The method provided by the invention realizes the process from the full manual rubbing manufacture to the complete digital manufacture, overcomes the defects of complicated process, low efficiency and high cost of the traditional rubbing manufacture process, and has very important significance on the fast proceeding of a large amount of rubbing treatment of stone inscription and stone inscription rubbing.

Description

technical field [0001] The invention relates to a stone carving rubbing method, in particular to a digital rubbing of stone carving characters. Background technique [0002] Stone carvings play an important role in inheriting history and culture. Most of them are carried by natural mountains dominated by limestone. Over the long years, due to the combined effects of natural and human factors, the surface of stone carvings has been continuously weathered and eroded. The protection of karst landforms and cliff carvings is a global conservation issue. Governments around the world attach great importance to the protection of stone carving culture. At present, most of the domestic stone inscriptions and inscriptions are preserved scattered, resulting in embarrassing storage, difficult collection, and limited use. The degree of loss and damage is quite serious, so that the value of cultural relics, historical materials and actual value of stone inscriptions cannot be used and bet...

AI Technical Summary

Problems solved by technology

[0005] From the rubbing production process above, it can be seen that the traditional production process is all done by hand, the process is cumbersome and time-consuming, and only one rubbing can be generated each time, which is inefficient

Manual production generally requires auxiliary facilities such as brackets and ladders. The production efficiency is low and there is a certain degree of danger. Stone carvings in places where brackets cannot be erected cannot be expanded.

Obtaining rubbings of stone carvings by manual rubbings is unsatisfactory due to the difficulty and heavy workload, and has a very bad influence on the original appearance and durability of stone carvings
