Description

A kind of hologram material database construction method

Technical field

The present invention relates to a kind of hologram material database construction method, belong to technical field of information processing。

Background technology

In the culture that China is bright, leave the cultural heritage of many preciousnesses。Cultural heritage is divided into matter input and non-material cultural heritage。China's long history of 5000 is pregnant with countless bright culture, and excavation and protection to these valuable cultural heritages also never stopped。Within 1985, China adds contracting party's ranks of " protection world culture and natural heritage pact ", constantly carries out the work declaring all kinds of world heritage between 30 years。So far, China has 45 world cultural heritages, and has 30 non-material cultural heritages to be selected in the non-material cultural heritage register of associating Educational, Scientific and Cultural Organization, occupies very important status in world cultural heritage。

For protecting large number of precious cultural heritage better, China set up state key cultural relics protection unit in various places, and has organized and implemented declaring and arranging of all kinds of tangible, intangible cultural heritage。At present, China has examined by 123 historical cultural cities, five batches of altogether name towns, over one hundred historical village, and ten big classes are amounted to 1530 remainder non-material cultural heritages lists List of National Intangible Cultural Heritage in。

But the dispersion of these cultural heritages is numerous and jumbled, face extinction at any time, it is carried out protection extremely urgent。In every cultural heritage protective measure, it is considered as can one of the mode of persistence cultural core that the digitized of legacy data is preserved。Current China has passed through media approach and cultural heritage is digitized typing and protection。

But the following difficulty of existence of China's cultural heritage protection:

1) region dispersion, not easily integrates

China is a country that vast territory and abundant resources, and unnumbered magnificent culture has been pregnant with on vast territory。But also just because of region vast so that China's cultural heritage is comparatively disperseed, and not easily integrates, and this situation is again with non-material cultural heritage for very。Such as this form of culture of dance of exorcising, exorcise to wave and be put into first national non-something lost register as China's national level non-material cultural heritage in Jiangxi, but dance culture of exorcising not only is present in again Jiangxi Area, according to made, exorcise and wave this form of culture in the ground such as Guangdong, Fujian, Anhui, Hunan, Hubei, but owing to region and humane difference have their own characteristics each again。2008, the dance culture of exorcising on the ground such as Shanxi, Anhui, Fujian, Guangdong, Gansu was put into first extension register of national non-material cultural heritage, has expanded the cultural system of dancing skill art of exorcising further。As can be seen here, owing to cultural heritage regional Characteristics comparatively substantially and is distributed dispersion, and effective information material interoperability is more weak at present, is unfavorable for effectively integrating of overall cultural heritage, and it is bigger that cultural architecture arranges difficulty。

2) form is numerous and jumbled, not easily preserves

In countless cultural heritages, the tangible physical legacy such as existing palace, pottery, also there is the invisible culture such as ballad, dancing, even also have engraving etc. to be attached to the skill in specific crowd, culture type is different, it is impossible to carry out limit by certain one or several protective measure merely。Such as tangible cultural heritage faces material aging even because of the loss that factor can not be resisted to produce, extinction；It is present in local nonmaterial culture virtually and then faces the not easily problem such as record。Generally speaking, how effectively the protection of current China cultural heritage all suffers from the predicament of preservation。For cultural heritage, it is inevitable to a certain extent that the loss of its body is even withered away, and how its record carrying out necessity and data to be retained, and becomes the focus that current culture protection worker endeavours to break through。

For overcoming above-mentioned technical problem, have started to Applied Digital visualization technique and culture data is preserved。Up to now the digital collecting of cultural heritage relies in the multimedia technology such as picture, video。

1) picture

In the digitized of cultural heritage data is retained, picture is one of means that range of application is the widest。No matter it is the material and cultures such as building, artware, or the nonmaterial culture such as skill, folk custom, data retention and reproduction can be carried out by this medium of picture。Additionally, due to picture is easy to collect, arrange, places and reproducing technology require the feature such as relatively low, also become current cultural heritage data for putting on display, the most commonly seen mode such as research。

2) audio frequency and video

Except preserving cultural information with picture, audio frequency and video also begin to occupy increasing proportion in cultural heritage data is retained。Compare picture medium, audio frequency and video have more deep, feature intuitively, and be more suitable for preserving invisible cultural heritage as abstract in folk rhyme, folk activity etc., it is widely used in the purposes such as cultural promotional display, teaching at present, has retained and many be on the verge of lost precious audio frequency and video data。

3) virtual animation

Above two data storage mode is all directly derived from the cultural heritage body of reality, in recent years, along with the development of computer technology, derives based on the virtual cartoon technique restored on real data basis。Compared to directly preserving culture body, virtual animation is more heavily weighted toward the integration to cultural materials and restores, and reaches the effect that many bodies in kind cannot realize, make cultural heritage data be able to more deep, intactly preserve and present。

4) multimedia interactive

In recent years, relying on the interaction technique Fang Xingzheng Chinese mugwort of the Internet, based on the unlatching of two-way propagation theory, cultural heritage data also steps into the multimedia interactive epoch。Multimedia interactive combines the various kinds of medias such as picture, video, animation, is integrated in a certain visualization medium, and provides all kinds of Interactive Experiences to user。Wherein comparatively successfully such as once well-known for a time " the virtual Forbidden City ", it is possible to freely walk in virtual the Forbidden City exchanges with other tourists, visits the Forbidden City collection etc., while cultural heritage is preserved, ensure that it active develops。

But there is following technical problem in current cultural heritage stored digital:

1) dispersion does not become system

Although China retains for the protection of cultural heritage and electronic data processing and has it long ago, but from As-Is, information between every field, each medium and data are also integrated not up to systematization。At present, China's cultural heritage extremely digital material majority resides in local museum or historical relic's protection mechanism, and by factors such as culture type, region, preservation media, data is comparatively disperseed, and lacks unified structuring combing and retention。This brings difficulty to undoubtedly the systematicness protection of future cultural legacy and research, is unfavorable for that cultural heritage is specified more effective protective measure by China。

2) existing media feature is respectively weak

The digitized of cultural heritage material is retained in the process being in a development。Being not difficult to find out in existing various media, the medium such as picture, audio frequency and video, animation is respectively arranged with feature, but is also individually present defect, such as problems such as plane picture three-dimensional can not react each partial information of historical relic exactly, audio frequency and video are linearly play restrictions。In today of technical development, need one new medium more three-dimensional, comprehensive, exercisable of searching badly, existing digit technology is merged, meet needs such as the preservation of cultural heritage data, reproductions better。

Summary of the invention

For overcoming the shortcoming existed in prior art, the goal of the invention of the present invention is to provide a kind of hologram material database construction method, utilizes the data base that the method that this century, invention provided builds, and structuring is strong, and the integrated level of information is high, it is simple to retrieval。

For achieving the above object, the present invention provides a kind of hologram material database construction method, and it at least includes:

S01: set up internal schema for hologram data and correlated characteristic based on relational database；

S02: define the external schema of market demand based on multiple applications；

S03: external schema corresponding relation and transformational relation in setting up；

S0: define externally used interface。

Compared with prior art, the present invention is utilized to provide the hologram data storehouse that hologram material database construction method builds to have the advantage that

1) structuring, systematization

The framework in hologram data storehouse is based on the realization of current hologram technology, by the combination of computer Yu holographic imaging technology, presents the 3-dimensional image with animation effect of solid, clear, various visual angles in screen。This data base can the feature of comprehensive multiple traditional sucroses such as picture, audio frequency and video, animation, originally scattered data are integrated, more completely, systematically by it are presented on the same medium。

2) information can integrated and search

The structure in hologram data storehouse, is not only the data in traditional digital medium simply merged。Relying on hologram technology, these data can be combined into the little entirety that each are different, it is simple to different dimensions screens disaggregatedly and transfers。Construction for Gan culture hologram data storehouse; its various data such as culture, Ceramics Culture, red culture of exorcising carry out integrating and being included into data base; this storehouse can realize the information retrieval of various dimension; as with region for condition, with the age for condition etc.; facilitate screening and the lookup of all kinds of data, the data of cultural heritage is preserved and future studies, protection provide more facility。

3) with the docking of other interactive modes

In the protection of cultural heritage, remove and focus on, to, outside the retention of historical summary, preserving with greater need for it is carried out " activity ", allowing these culture continue to retain in society。Therefore, culture data, on the basis that appropriate typing achieves, also should actively seek international communication, universal channel。In in the past traditional digital media, owing to different medium is difficult to be integrated together, the reasons such as data system is perfect not, cultural heritage data cannot be applied in the aspects such as such as teaching, science popularization as the entirety of one or a certain class comparatively system。The framework in hologram data storehouse, by the integrity using its data flexibly and the convenience taken, meet the use needs of different levels, different purposes, really the data saved merely is activated, expand the range of application of China's cultural heritage data, and then ensure its activity development。

Detailed description of the invention

The present invention is described in detail below in conjunction with accompanying drawing。

Fig. 1 is the flow chart of hologram material database construction method provided by the invention, as it is shown in figure 1, hologram material database construction method provided by the invention at least includes:

Internal schema is set up for hologram data and correlated characteristic based on relational database；

The external schema of market demand is defined based on multiple applications；

External schema corresponding relation and transformational relation in setting up；

Define externally used interface。

More specifically, the method that method provided by the invention builds data is utilized to include:

Data base involved by information management system designs in five steps: Database Requirement Analysis, conceptual design, logical design, physical Design and loading test。

The task of Database Requirement Analysis is for data stream by operational control document fluidisation, divides the border between theme, draws out DFD figure, and completes corresponding data dictionary。

The task of conceptual design is from DFD, draws out the E-R graph of this theme, and lists the skeleton table of each entity and relation。

The task of logical design is from E-R figure and corresponding skeleton table, it is determined that the table name attribute of each entity and relation。

The task of physical Design determines that the type of all properties, width and span, designs the major key of base table, by all of table name and field name English, it is achieved physics builds storehouse, completes atabase Physical Design dictionary。

Loading the overall process that test job works through program test, whole typing, amendment, inquiry, process work all can be considered the loading test job to data base。Design a good Data in Information Management System storehouse, except the function met required by system, it is necessary in accordance with following principle:

The number of base table is more few more good。The number of major key is more few more good。Key is the instrument connected between table, and major key is more few, and the connection between table is more simple。The number of field is more few more good。The design of all base tables all should meet third normal form as far as possible。In the design of data base, how to process the relation of multi-to-multi and how to design major key, being two problems having bigger difficulty, needing emphasis to consider。We analyze the system core technology of this problem from aspects such as SQL application, database Normal Formula and query optimizations and realize difficult point and solve emphatically。

The above is only that embodiments of the present invention describe in detail; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and modification, these improve the protection domain that also should be regarded as invention with modification。
