Description

Technical Field

[0001] The present invention relates to the technical field of cultural heritage dissemination, and in particular to a cultural heritage information digital dissemination device and method. Background Art

[0002] Cultural heritage refers to the material and intangible wealth with historical, artistic, scientific or cultural value created and passed down by mankind in the course of historical development. These heritages not only reflect the richness and diversity of human civilization, but are also an important link between the past, present and future. Cultural heritage is usually divided into tangible cultural heritage and intangible cultural heritage. Tangible cultural heritage refers to movable and immovable cultural relics and sites with historical, artistic or scientific value. Intangible cultural heritage refers to traditional cultural expressions handed down from generation to generation, as well as related tools, objects, handicrafts and cultural spaces. In order to promote cultural heritage, digital communication devices are used for extensive promotion. Modern digital technology is used to display, disseminate and interact with cultural heritage information. Equipment or systems provide users with immersive and interactive experience through the integration of multimedia technology, interactive interface and intelligent technology, thereby enhancing the understanding and appreciation of cultural heritage.

[0003] There are still some problems in the use of existing cultural heritage information digital communication devices. Some physical objects are too valuable and inconvenient to display. Using imitations for display also requires special maintenance, and the maintenance cost is high. The use of holographic projection technology can reduce this type of cost. However, when using holographic projection technology, there is also the influence of light intensity, temperature and humidity.
