The system can accurately and efficiently realize the functions of cultural relic identification and detection, acquisition of cultural relic related information, 3D appreciation of cultural relic and interaction between users and cultural relics. Meanwhile, it can provide users with immersive experience, and facilitate the identification and appreciation of cultural relics for fans of cultural relics, thus providing strong support for the realization of digital management of cultural relics.
