Cultural relic anti-theft spectrum monitoring method and system based on filter wheel camera

Abstract

The invention discloses a cultural relic anti-theft spectrum monitoring method and system based on a filter wheel camera. The method comprises the following steps: firstly, determining a coding tag bit and a spectrum characteristic on a to-be-monitored cultural relic; then determining the type of an optical filter on a filter wheel according to the spectral characteristics, and rotating the optical filter on a camera shooting lens; shooting a frequency spectrum image; and finally, state information of the to-be-monitored cultural relic is judged. According to the cultural relic anti-theft spectrum monitoring method provided by the invention, real-time monitoring and coding of the cultural relic are realized by placing the label with the specific spectrum on the surface of the cultural relic, the coding label is identified and the code of the coding label is obtained by using a method of switching the optical filter by using the filter wheel, and when the specific spectrum can be detected, it is considered that the cultural relic is not stolen; and when the specific spectrum cannot be detected, it is considered that the cultural relics have the risk of being stolen. The method is low in cost and high in automation degree, manual guard is not needed after installation is completed, and the system can achieve automatic real-time monitoring. The measurement accuracy is high, false alarms are not likely to happen, and high-reliability monitoring can be achieved.

Description

technical field [0001] The invention relates to the technical field of cultural relics monitoring, in particular to a anti-theft spectrum monitoring method for cultural relics based on a filter wheel camera. Background technique [0002] The current situation of cultural relics protection is not optimistic. Many cultural relics such as stone statues and murals are often partially damaged. [0003] At present, with the continuous development of science and technology, the monitoring methods used for cultural relics protection are also more diversified, and new monitoring methods emerge in endlessly. At present, there are many monitoring methods for cultural relics protection, and each method has its advantages and disadvantages, such as ranging method, vibration measurement method, video monitoring method, multi-spectral monitoring method, etc. For example, the application number is CN201610419995.4, and the patent name is a built-in passive monitoring cultural relic capsule...

AI Technical Summary

Problems solved by technology

For example, the application number is CN201610419995.4, and the patent name is a built-in passive monitoring cultural relic capsule and its manufacturing method. There is a transparent observation window, and the temperature and humidity in the capsule can be obtained through the monitoring module, so it is impossible to monitor whether the cultural relics are stolen or not.

Another example is that the patent application number is CN201320618637.8, and the patent name is a wireless out-of-position alarm system based on RFID. The out-of-position alarm of cultural relics is realized through RFID tags, but the tags are set on the base of the cultural relics, not on the cultural relics themselves. The cultural relics were stolen and could not be found in time, posing a security risk
