Abstract: Cultural relics are the crystallization of historical, artistic, and scientific values in the development of human civilization, and it contains historical and cultural information. Cultural relics digitization is an important link for their protection, restoration, and reconstruction. As an important supplement of traditional cultural relics digitization ways, hyperspectral remote sensing can quickly and non-destructively obtain the material, pigment, and processing traces of cultural relics, and provide physical and chemical properties of cultural relics surface for the digital resources of cultural relics. In this paper, the equipment and methods of hyperspectral information collection in the field are summarized and analyzed, and then the key technologies of hyperspectral information processing in the field of cultural relics protection are reviewed, and summarized the four aspects of information increase, information extraction, information classification and visualization, and compares and analyzes the common methods. Based on the comparison and analysis of the common methods, the typical application of hyperspectral technology in the field of cultural preservation is summarized, including the analysis and recognition of pigment species, the extraction of hidden information and the recognition of repaired traces. Finally, the future research directions of hyperspectral cultural relics applications are prospected.
