Description
Technical field
The present invention relates to a kind of Portable non-contact historical relic profile and texture collection equipment, it is mainly used in historical relic device shape three-dimensional
Architecture digital and texture information collection are obtained, so as to further carry out artifact cohort study, protection and digitlization natural science
The foundation in shop.
Background technology
Rare cultural relics are digitized with processing, network Digitalization Process of Museums system is built up, can preferably solve
Certainly abundant showpiece and limited exhibition space, the contradiction between the time, further open up museum objects protection, research and open up
The frontier shown, can also realize the modernization of museum management means.Have that profile is complicated due to artifact, should not contact,
The features such as texture information enriches, thus it is how rapid and accurate obtain that artifact is three-dimensional and texture information turns into a key point.
Wherein, digitlization task mainly includes the acquisition and processing of profile, inner chamber and texture information.
Existing cultural relic digitalization method mainly has：Photogrammetric technology, three-dimensional laser scanning technique, laser triangulation and
Industrial Computed Tomography.Photogrammetric technology is by gathering cultural relic images, then imported into host computer and carry out feature point extraction with matching, most
The threedimensional model and surface texture for obtaining historical relic are rebuild afterwards, because it only needs to shoot historical relic picture, in host computer by specialty
Image processing software carries out picture processing, so the features such as having simple, convenient use, rebuild quick, extensive
Applied to three-dimensional reconstruction field；Three-dimensional laser scanning technique, it can quickly obtain solid by laser ranging and two axle movement
Intuitively threedimensional model, and its reflected light path is returned by transmitting light path, therefore do not blocked and influence by debris, to a wide range of text
Research field in terms of thing structure, volume has the unrivaled advantage of other modes；Laser triangulation law technology can be quick
Locus and the structural information of plane historical relic are obtained, there is more advantage for measurement small range object；Industrial Computed Tomography, according to
It is operated according to decrease and absorption characteristic in historical relic is detected is radiated, finally with computer disposal and Image Reconstruction Technology
To show, therefore it can be measured to historical relic device shape inner chamber.
Above technology respectively has feature, but there is following defect for the data acquisition of historical relic device shape：Photogrammetric skill
Art mode, texture information resolution ratio that it is isolated is low, with projection distortion, and obtaining outline point cloud, often noise is more,
Inconvenience is brought to carry out archaeological research；Three-dimensional laser scanning technique, respective scanned equipment price is expensive, is carrying out outwork
Shi Yi is influenceed by weather environment and light, and simple three-dimensional laser scanning technique can't effectively extract texture color letter
Breath, still needs the cooperation of other equipment；For laser triangulation, pure laser trigonometry can not extract texture color information,
Still need the cooperation of other equipment；The huge inconvenience of Industrial Computed Tomography equipment volume is carried, and measurable object size is smaller, price
It is expensive, it is impossible to obtain the reasons such as texture information, be difficult to apply to historical relic device shape profile and texture digital area.
The content of the invention
Study, carry present invention aims at the shortcoming for the existing method carried out to historical relic device shape in three-dimensional reconstruction
For a kind of Portable non-contact historical relic profile and texture collection equipment, realize Quick Acquisition to historical relic device shape three-dimensional data,
Historical relic device shape contour structures and complete texture information unfolded image are quickly obtained, portable historical relic three-dimensional digital has been invented
Equipment, can be that historical relic's protection and cohort study provide more accurate and comprehensive digital model.Present invention mainly solves
Technical problem has：
1. present invention mainly solves the resolution ratio that prior art collects historical relic texture information it is low, with image deformation and profile
The shortcomings of point cloud noise is more.
2. the present invention needs to solve the integration problem that profile collection and texture information are gathered, and realizes profile and texture letter
Cease acquisition system can not quick separating and carry problem.
To realize accurate actual response and measurement historical relic profile and the above-mentioned purpose of data texturing, present invention employs as follows
Technical scheme：
