Cultural relic three-dimensional modeling method

Abstract

The invention discloses a cultural relic three-dimensional modeling method which comprises the following steps of S1, shooting environment preparation, S2, cultural relic surrounding acquisition, S3,cultural relic orientation angle adjustment to realize omnibearing acquisition, S4, data preprocessing, and S5, cultural relic three-dimensional automatic modeling, and relates to the technical fieldof image acquisition. The invention discloses the cultural relic three-dimensional modeling method, cultural relics are comprehensively collected and automatically positioned, the one-time overall three-dimensional modeling of the cultural relics can be realized, the problem that three-dimensional modeling of the bottom and the lower portion of the cultural relic needs manual participation, and consequently the precision of a three-dimensional model is not uniform is solved, the refined three-dimensional modeling of the cultural relic with the small size and thickness is achieved, and therefore, the modeling time is greatly shortened, the application range of three-dimensional modeling is enriched, and the three-dimensional digitization work of the cultural relics can be promoted and developed.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to a three-dimensional modeling method for cultural relics. Background technique [0002] As the digital protection of cultural relics has been promoted to a national strategy, 3D modeling of cultural relics has become the most important technology and data guarantee for the digital protection of cultural relics. [0003] At present, most of the cultural relic modeling fields use 3D laser scanning technology. This technology applies the principle of laser ranging and is a dynamic measurement system. With the help of 3D laser instrument and processing software, the 3D geometric model of the object can be obtained initially. Color and texture maps, and finally generate a complete digital 3D model. 3D laser scanning can only provide accurate spatial geometric information of objects, and the later texture mapping requires a lot of manual participation, resulting in a long 3D ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for three-dimensional modeling of cultural relics, which avoids the geometric model and texture of the existing three-dimensional laser scanning modeling The lack of separation of the mapping process solves the problem that the existing image modeling cannot complete the unified modeling of cultural relics and the bottom, and cannot realize the 3D modeling of cultural relics with small size and thickness
