Description

A holographic video material indexing method

technical field

The invention relates to a holographic video material indexing method, which belongs to the technical field of information processing.

Background technique

In our splendid culture, many precious cultural heritages have been left behind. Cultural heritage is divided into tangible cultural heritage and intangible cultural heritage. The 5,000-year long history of our country has bred countless splendid cultures, and the excavation and protection of these precious cultural heritages have never stopped. In 1985, China joined the ranks of signatories to the Convention on the Protection of World Cultural and Natural Heritage, and has continuously carried out the work of applying for various world heritages for 30 years. So far, my country has 45 items of world cultural heritage, and 30 items of intangible cultural heritage have been selected into the UNESCO list of intangible cultural heritage, occupying a pivotal position in the world cultural heritage.

In order to better protect a large number of precious cultural heritages, our country has set up national key cultural relics protection units in various places, and organized the declaration and arrangement of various tangible and intangible cultural heritages. At present, my country has approved 123 famous historical and cultural cities, five batches of more than 100 famous historical and cultural villages and towns, and a total of more than 1,530 intangible cultural heritage items in ten categories have been included in the national intangible cultural heritage list.

However, these cultural heritages are scattered and complex, and are facing extinction at any time, so it is imminent to protect them. Among various cultural heritage protection measures, the digital preservation of heritage materials is considered to be one of the most permanent ways to preserve the cultural core. At present, my country has digitally entered and protected cultural heritage through various media channels.

However, the protection of cultural heritage in my country has the following difficulties:

1) Geographically scattered and difficult to integrate

my country is a country with vast land and abundant resources. The vast land has bred countless splendid cultures. But it is also because of the vastness of the territory that our country's cultural heritage is relatively scattered and difficult to integrate. This situation is especially true for intangible cultural heritage. Such as the cultural form of Nuo dance, Jiangxi Nuo dance was included in the first batch of national intangible cultural heritage list as my country’s national intangible cultural heritage, but Nuo dance culture does not only exist in Jiangxi. According to data records, Guangdong, Fujian Nuo dance is a cultural form in China, Anhui, Hunan, Hubei and other places, but each has its own characteristics due to regional and cultural differences. In 2008, Nuo dance culture in Shanxi, Anhui, Fujian, Guangdong, Gansu and other places was included in the first batch of extended list of national intangible cultural heritage, further expanding the cultural system of Nuo dance art. It can be seen that due to the obvious regional characteristics of cultural heritage and scattered distribution, and the current effective interoperability of information materials is weak, which is not conducive to the effective integration of the overall cultural heritage, and the systematic arrangement of culture is relatively difficult.

2) The shape is complex and difficult to preserve

Among the countless cultural heritages, there are not only tangible material heritages such as palaces and ceramics, but also intangible cultures such as songs and dances, and even carvings and other skills attached to specific groups of people. The cultural forms are different, and it is impossible to simply use one or several protective measures to exhaust. For example, tangible cultural heritage faces the aging of materials and even the loss and disappearance due to irresistible factors; while the invisible local intangible culture faces problems such as difficulty in recording. Generally speaking, the protection of cultural heritage in our country is facing the dilemma of how to preserve it effectively. For cultural heritage, the loss or even extinction of its ontology is inevitable to some extent. How to make necessary records and data preservation for it has become the focus of current cultural protection workers' efforts to make breakthroughs.

In order to overcome the above-mentioned technical problems, digital visualization technology has been applied to preserve cultural materials. So far, the digitization of cultural heritage has concentrated on relying on multimedia technologies such as pictures and videos. However, the current digital storage of cultural heritage has the following technical problems: it is scattered and not systematic, and the creators have not indexed the keywords according to the user's word habits, which is inconvenient for retrieval and query.

Contents of the invention

In order to overcome the shortcomings in the prior art, the object of the present invention is to provide a method for indexing holographic video materials, which is easy to retrieve and query, has high retrieval efficiency and fast query speed.

In order to achieve the purpose of the above invention, the present invention provides a method for indexing holographic video materials, which at least includes:

Establish and regularly update the keyword database based on the search results of holographic videos on the Internet;

Adjust keyword weight according to keyword usage frequency;

Establish and update the user's local keyword database according to the user's frequency of use;

Based on the above keyword library and the characteristics of the indexed video material, alternative keywords are given;

The indexing keyword is determined according to the user's choice to complete the indexing.

Compared with the prior art, the holographic video material indexing method of the present invention is convenient for retrieval and query, and the retrieval efficiency is high and the query speed is fast.
