Description

Technical Field

[0001] The present invention relates to the fields of astronomy teaching and astronomy popularization, and in particular to a full-globe AI planetarium. Background Art

[0002] Traditional astronomy education and astronomical science facilities cannot fully meet the growing demand for astronomy education and popularization. Planetarium programs are rigid and lack interaction, and their large coverage radius makes astronomy education and popularization costly and inefficient. Most celestial globes are located in the upper hemisphere. Slightly more advanced digital planetariums can broadcast astronomical programs in the upper hemisphere, but these programs are also less interactive and cannot show the entire celestial sphere. In recent years, full-sphere planetariums have emerged, but these are only full-sphere models with fixed coordinate lines and constellation patterns. They cannot dynamically demonstrate the movement of stars, the alternation of day and night, the changing of seasons, or special astronomical phenomena at any time and location. They cannot calibrate and demonstrate celestial coordinate systems or stellar coordinate values. Therefore, we are developing a global screen AI planetarium. This device, utilizing AI astronomical image generation technology and fisheye projection technology, intelligently generates celestial images at any time and location, automatically demonstrating the apparent motions of various celestial bodies; automatically introducing both foreign constellation systems and the Chinese star system; and automatically demonstrating celestial coordinate systems and calibrating stellar coordinates. This significantly enhances the automation and intelligence of astronomy teaching and popular science equipment. Technological innovation empowers astronomy instruction, enhancing interaction, improving efficiency, stimulating interest, and disseminating knowledge. This is crucial for cultivating national space science talent from an early age, given the country's medium- and long-term space science development plan. Summary of the Invention
