Automatic historical relic fragment splicing method

Abstract

The invention discloses an automatic historical relic fragment splicing method. The method comprises steps that to-be-spliced historical relic fragments are scanned, and a three-dimensional model of each historical relic fragment is established; meshing of the three-dimensional model is carried out; surface division operation of the three-dimensional model is carried out, vertexes on a same smooth surface are divided into one group, and the vertexes contained by each smooth surface are acquired; an integral invariant of each vertex of the historical relic fragments is calculated; according to acquired sections and the integral invariant of each vertex, characteristic point pairs of each section having the equal integral invariants under a set threshold scope are acquired; a greedy algorithm is employed to acquire matching relationships of the fragments according to the characteristic pairs, and the historical relic fragments are spliced and matched according to the matching relationships.

Description

technical field [0001] The present invention relates to a method for mosaicing cultural relics based on three-dimensional image graphics simulation, involving patent classification number G physics G06 calculation; calculation; Set-up of a different image G06T3 / 40 scaling of the entire or part of the image bit-by-bit. Background technique [0002] The existing splicing and restoration process of fragments of cultural relics needs to rely on the experience and imagination of archaeological restoration personnel to complete the splicing and restoration of a fragmented cultural relic. The manual splicing method is expensive, takes a long period, and is likely to cause secondary damage to the cultural relics.

Problems solved by technology

[0002] The existing process of splicing and repairing fragments of cultural relics needs to rely on the experience and imagination of archaeological restoration personnel to complete the splicing and repairing of a fragmented cultural relic. The manual splicing method is costly and takes a long time, and it is easy to cause secondary damage to cultural relics

[0003] In the prior art, there is also a method based on digitizing two-dimensional irregular fragment images, comparing the digitized fragment images to see if there is an intersection, and then finding the most similar curve based on a vector modulo fragment matching algorithm if there is an intersection. Fragments, and splicing of fragments, but the two-dimensional model cannot accurately reflect the overall characteristics of the cultural relics

[0004] The latest research and development direction in the field is to collect and classify the data of cultural relic fragments, use Wiimote to interactively control the movement of the model, perform complementary splicing and template matching virtual restoration of cultural relic fragments, and then use 3D printing to perform physical restoration of cultural relics, but there are 3. The splicing accuracy is not high, it is sensitive to noise, or the splicing efficiency is low, etc.
