Bronze ware inscription information extraction and recording method based on three-dimensional reconstruction technology

Abstract

The invention discloses a bronze ware inscription information extraction and recording method based on a three-dimensional reconstruction technology. Bronze ware inscriptions are subjected to three-dimensional reconstruction by the three-dimensional reconstruction technology so as to obtain a high-precision three-dimensional bronze ware inscription model; the bronze ware inscriptions are cast inscriptions or engraved inscriptions; the high-precision three-dimensional bronze ware inscription model records grooves or bulges of such characters under high precision; after the three-dimensional model is subjected to curvature analysis, smoother positions without the inscriptions on the model are low in curvature, and positions with inscriptions are high in curvature, so that the character part generates curvature change; by capturing and drawing of characteristic lines at the high-curvature positions, form information of the bronze ware inscriptions is extracted and recorded under high precision; most of the bronze ware inscriptions are not positioned on the same plane; the characteristic lines extracted and recorded based on curvature analysis of the three-dimensional model are form characteristics in a three-dimensional space; by positive projections of characters one by one, a positive projection image of the bronze ware inscriptions is acquired. According to the bronze ware inscription information extraction and recording method, the precision of the inscription information and the efficiency of an extraction process can be guaranteed.

Description

technical field [0001] The invention relates to a method for extracting bronze inscription information, in particular to a method for extracting and recording bronze inscription information based on three-dimensional reconstruction technology. Background technique [0002] At present, the known recording methods of bronze inscriptions are mainly limited to two methods: copying and rubbing. [0003] The imitation refers to the later generations "recording with the method of drawing according to the sample" according to the text form of the bronze inscriptions. It is a description of the strokes of the bronze inscriptions. The recorded result is only the general stroke characteristics of the bronze inscriptions. It is a subjective judgment and record. Undoubtedly, it caused a great loss of bronze inscription information; [0004] Rubbing, on the other hand, is an ancient traditional Chinese art form, which is still applied to the information recording of bronze inscriptions u...

Problems solved by technology

[0005] However, without rubbings, research on archaeology and cultural relics that relies on rubbings is hindered

The unique and distinctive black-and-white form, figure-base relationship, shape outline and other visual information presented by rubbing images have special value and significance for the research on modeling and composition in the field of art, and these features are not available and irreplaceable in ordinary photos
