Research On Immovable Cultural Relics Security System Based On Special Spectrum Technology

As an irreplaceable and non-renewable special resource,immovable cultural relics have witnessed and recorded the development process of human civilization and are of great value.At present,due to the lack of security monitoring technology and equipment that can be effectively applied to immovable cultural relics,man-made damage and excavation are emerging one after another.Protecting immovable cultural relics resources and building a strong cultural relics safety line are the urgent needs of cultural relics protection.It is urgent to study a lossless,real-time and effective immovable cultural relics monitoring system.Relying on the national key R & D project "Research on key technologies and equipment of security(anti-theft and anti-destruction)of immovable cultural relics(project number: 2020YFC1522900)",this thesis designs and develops a security monitoring system of immovable cultural relics based on special spectrum technology to realize the protection of immovable cultural relics.The main work of this thesis is as follows:(1)The factors affecting the imaging quality of hyperspectral camera are explored,and the standard data acquisition specification of hyperspectral camera is established.The reflectance spectra of cultural relics are analyzed.According to the spectral characteristics and the needs of cultural relics protection,the special spectrum tags of notch plate and quantum dot are designed.(2)According to the measurement requirements,the special spectrum monitoring equipment is designed,the design of system light source is completed,and the special spectrum security monitoring hardware system with very low impact on the appreciation of cultural relics,strong concealment and no damage to cultural relics is realized.(3)Based on the special spectrum monitoring equipment,the special spectrum security monitoring software system is designed.Through the design of reasonable image processing method,the special spectrum tag is recognized from the image collected by hardware,and the determination of cultural relic safety is realized by designing the cultural relic safety discrimination algorithm.The software system realizes the functions of login,real-time monitoring,parameter configuration,historical data query and so on.The reflection spectrum database of immovable cultural relics is established,and the search and matching of spectral data are realized.The reliability of the special spectrum security monitoring system is verified by experiments.The output of the system in various scenarios is tested.The results show that the system can correctly judge the safety status of cultural relics,and can also detect the changes of system hardware in time to remind maintenance personnel to deal with them.Compared with the traditional security monitoring methods of immovable cultural relics,the special spectrum security monitoring system of immovable cultural relics designed in this thesis has high reliability and automation,no damage to cultural relics and does not affect the viewing of cultural relics.It has good innovation and practical value.Various characteristics are suitable for the security monitoring of immovable cultural relics.
