Detailed Description
The invention provides a cultural relic protection monitoring method based on contrast label material spectrum difference monitoring, which is shown in figure 1 and comprises the following steps: pre-manufacturing a material comparison label; the material comparison label is provided with a material which is different from the material of the surface of the preset detection position on the detected cultural relics; during monitoring, material spectrum information of a preset detection position on the measured cultural relics is collected in real time, whether the measured cultural relics are abnormal is judged according to whether the difference of the material spectrum information of the preset detection position on the monitored cultural relics, which is collected by monitoring, relative to the material spectrum information of the material comparison label, is changed, and cultural relic protection early warning operation is executed when the measured cultural relics are abnormal.
According to the cultural relic protection monitoring method, material spectrum information is used as identification information, and material spectrum information difference comparison is carried out between material comparison labels with different materials and preset detection positions of the monitored cultural relics, so that cultural relic protection monitoring is realized; therefore, if the detected cultural relics are stolen, moved or the local parts of the preset detection positions are damaged, the detected cultural relics can be detected due to the change of the material spectrum information of the preset detection positions of the detected cultural relics, the conditions of theft prevention, damage and the like of the cultural relics can be comprehensively monitored, and the method is based on the material spectrum information for identification, so that the method is not interfered by ambient light, cannot interfere with the monitoring result by using a physical photo, has fewer technical defects, and can be more comprehensively applied to different cultural relic protection monitoring environments.
In the specific application implementation, the prefabricated material contrast label can be a block or a sheet directly formed by materials, or a structural member formed by attaching or fixing another material on the surface of a substrate of the block or the sheet. The specific mode of collecting and recording the material spectrum information of the preset detection position on the detected cultural relics shown in the application scene in fig. 2 can be that a multispectral image of the detected cultural relics 2 is shot by utilizing a multispectral camera 1, and the spectrum information of one or more appointed local pixel areas in the pixel areas of the detected cultural relics in the multispectral image is used as the material spectrum information of the preset detection position on the detected cultural relics, wherein each appointed local pixel area is a pixel array area containing m rows and n columns of pixels, and m and n are set pixel array parameter values which are all positive integers; typically, each specified local pixel region mxn is not greater than 30×30 to avoid excessive computation.
The preset detection position on the measured cultural relics can be selected according to the specific conditions of the measured cultural relics; for example, a position point on the surface of the measured cultural relic, which is convenient for shooting and observation by a multispectral camera, can be selected as a preset detection position so as to monitor whether the measured cultural relic moves in a position change or not through comparison; for another example, some vulnerable parts and other position points on the surface of the measured cultural relics can be selected as preset detection positions, so that after the collected material spectrum information is observed through a multispectral camera, whether the measured cultural relics are damaged, aged and other abnormal conditions are compared and monitored. Meanwhile, the preset detection position on the measured cultural relics is relative to the photographed image of the multispectral camera, that is, one or more pixel area positions on the measured cultural relics are designated as the preset detection positions in the photographed image of the multispectral camera, so that even if the measured cultural relics move, the preset detection positions designated in the photographed image of the multispectral camera do not move.
During monitoring, the difference comparison processing of the material spectrum information of the preset detection position on the detected cultural relics relative to the material spectrum information of the material comparison label and the judgment processing of whether the detected cultural relics are abnormal can be completed by computer equipment with information operation processing capability. Meanwhile, the difference comparison technology of the material spectrum information is also a relatively mature prior art, and a detailed description is not expanded here. The comparison mode for judging whether the difference of the material spectrum information of the preset detection position on the measured cultural relics relative to the material spectrum information of the material comparison label is changed can be that the material spectrum information difference of the current moment obtained after real-time acquisition is compared with the material spectrum information difference of the previous 1 moment (or the previous k moment), or the material spectrum information difference of the current moment obtained after real-time acquisition is compared with the material spectrum information difference average value of the previous k moments, wherein k is an integer larger than 1, and the value of k is not more than 10 generally so as to avoid excessive redundancy of calculated amount and the comparison calculation efficiency of the material spectrum information difference; the difference of the material spectrum information is a judging mode of change, generally, the change amount of the material spectrum information of the preset detection position on the measured cultural relics relative to the difference of the material spectrum information of the material comparison label is judged, if the change amount is not larger than a preset material spectrum information difference change amount threshold value, the material spectrum information difference is judged to be unchanged, otherwise, the material spectrum information difference is judged to be changed. The cultural relic protection and early warning operation executed when the occurrence of the abnormality of the measured cultural relic is judged can be in the operation modes of displaying early warning information, executing early warning audible and visual alarm, sending remote early warning information number and the like.
In the implementation of specific application, the specific implementation mode for judging whether the detected cultural relics are abnormal or not can have various forms when the cultural relic protection monitoring method based on the comparison label material spectrum difference monitoring is adopted for monitoring. The invention is further illustrated by the following examples.
Embodiment one:
as an optional implementation manner, in the cultural relic protection monitoring method based on the contrast label material spectrum difference monitoring, the material contrast label can be designed and fixedly arranged at a preset label arrangement position on the monitored cultural relic; here, the preset label arrangement position on the measured cultural relic is different from the preset detection position, meanwhile, a position point on the surface of the measured cultural relic, which is convenient for the multispectral camera to shoot and observe, can be selected as the preset label arrangement position, so that the material spectrum information of the material contrast label of the preset label arrangement position is acquired and observed through the multispectral camera, and meanwhile, the preset label arrangement position on the measured cultural relic is relative to the shooting image of the multispectral camera, that is, one or more pixel area positions on the measured cultural relic are designated in the shooting image of the multispectral camera as the preset label arrangement position, so that even if the measured cultural relic moves, the preset label arrangement position designated in the shooting image of the multispectral camera does not move; in the monitoring process, when the material spectrum information of the preset detection position on the measured cultural relics is monitored and collected, the material spectrum information of the material comparison label of the preset label arrangement position on the measured cultural relics is also monitored and collected.
In this way, when the cultural relic protection monitoring method based on the contrast label material spectrum difference monitoring is adopted for monitoring, the specific mode for judging whether the monitored cultural relic is abnormal is designed as follows: judging whether the difference of the material spectrum information of the preset detection position on the monitored and collected measured cultural relics relative to the material spectrum information of the material comparison label of the preset label arrangement position is kept unchanged; if the difference is kept unchanged, judging that the measured cultural relics are not abnormal; if the difference changes, the detected cultural relics are judged to be abnormal.
According to the monitoring scheme, the material comparison label is fixedly arranged on the measured cultural relics, the monitoring mode is to collect and detect whether the material spectrum information difference between the preset detection position and the preset label arrangement position on the measured cultural relics changes or not, the material comparison label has the main effect of enhancing the material difference between the material comparison label and the material on the surface of the measured cultural relics, so that the material spectrum difference is more obvious, and the error of monitoring and judging is reduced; meanwhile, as the material spectrum information of the preset detection position and the preset label arrangement position on the detected cultural relics are required to be acquired and detected simultaneously for difference comparison during monitoring, any position between the detection position and the preset label arrangement position changes, the material spectrum information difference value between the detection position and the label arrangement position changes, the multipoint monitoring on the detected cultural relics is realized, and the sensitivity of monitoring abnormal conditions such as displacement or damage of the detected cultural relics is improved.
In this embodiment, as a preferred design, a plurality of material areas may be disposed on the surface of the prefabricated material comparison label, and each material area may be disposed with a different kind of material. In this way, when judging whether the measured cultural relics are abnormal, the material spectrum information of the preset detection position on the monitored and collected measured cultural relics is respectively compared with the material spectrum information of each material region in the material comparison label of the preset label arrangement position, and if and only if the material spectrum information of the preset detection position is respectively unchanged relative to the difference of the material spectrum information of each material region in the material comparison label of the preset label arrangement position, the measured cultural relics are judged not to be abnormal; and judging that the measured cultural relics are abnormal if only the difference between the material spectrum information of the preset detection position on the collected measured cultural relics and the material spectrum information of any material area in the material comparison label corresponding to the arrangement position of the preset label is monitored to change.
According to the monitoring scheme, the plurality of material areas are arranged on the surface of the material comparison label, and different kinds of materials are arranged in each material area, so that on one hand, the irreplaceability of the material comparison label can be enhanced, and the situation that the material comparison label is imitated and impersonated can be avoided; on the other hand, when judging whether the measured cultural relics are abnormal, the material spectrum information of the preset detection position on the measured cultural relics which are collected through monitoring is compared with the material spectrum information of each material region in the material comparison label of the preset mark arrangement position, so that the identification amount of the comparison information is increased, and because a plurality of material regions on the material comparison label can have certain arrangement positions, if the measured cultural relics are subjected to translation, rotation, local damage displacement and other conditions, the arrangement positions of the material regions on the material comparison label can be changed in rotation and the like, so that the change of the material spectrum information difference value is caused, and the monitoring mode is also more beneficial to accurately judging whether the measured cultural relics are subjected to abnormal conditions such as rotary displacement or local damage.
In this embodiment, as another preferred scheme, a plurality of preset label arrangement positions on the measured cultural relics may be designed, and material comparison labels with different material types are fixedly provided on the preset label arrangement positions on the measured cultural relics. In this way, when judging whether the measured cultural relics are abnormal, the material spectrum information of the preset detection positions on the monitored and collected measured cultural relics are respectively compared with the material spectrum information of the material comparison labels of the arrangement positions of the preset labels, and if and only if the material spectrum information of the preset detection positions is respectively unchanged relative to the difference of the material spectrum information of the material comparison labels of the arrangement positions of the preset labels, the measured cultural relics are judged not to be abnormal; and judging that the measured cultural relics are abnormal if only the difference between the material spectrum information of the preset detection position on the collected measured cultural relics and the material spectrum information of the material comparison label corresponding to the arrangement position of any preset label is monitored to change.
According to the monitoring scheme, the material comparison labels with different material types are respectively and fixedly arranged at the plurality of preset label arrangement positions on the measured cultural relics, when judging whether the measured cultural relics are abnormal or not, the material spectrum information of the preset detection positions on the monitored cultural relics and the material spectrum information of the material comparison labels at the preset label arrangement positions are respectively compared, on one hand, the identification amount of the comparison information is increased, on the other hand, if the measured cultural relics are subjected to translation, rotation, local damage displacement and the like, one or more of the material comparison labels can be displaced, and accordingly the change of the material spectrum information difference value is caused, and therefore the monitoring mode is also more beneficial to accurately judging whether the measured cultural relics are subjected to abnormal conditions such as rotary displacement or local damage and the like.
Embodiment two:
the monitoring scheme of the first embodiment has a technical feature that a material comparison label needs to be fixedly arranged at a preset label arrangement position on a measured cultural relic, so that the technical requirement is not applicable to some cultural relic types because the material comparison label is inconvenient to arrange or the label is arranged to cause corrosion damage to the surface of the cultural relic.
For these situations, another alternative implementation manner of the second embodiment may be adopted, and in the cultural relic protection monitoring method based on the comparison tag material spectrum difference monitoring of the present invention, the material comparison tag may not need to be fixedly disposed on the monitored cultural relic, but the material spectrum information of the material comparison tag is stored and recorded after being collected in advance.
Then, during monitoring, the specific mode for judging whether the measured cultural relics are abnormal is designed as follows: judging whether the difference of the material spectrum information of the preset detection position on the monitored and collected measured cultural relics relative to the material spectrum information of the stored and recorded material comparison label is kept unchanged; if the difference is kept unchanged, judging that the measured cultural relics are not abnormal; if the difference changes, the detected cultural relics are judged to be abnormal.
According to the monitoring scheme, a material comparison label is not required to be arranged on a monitored cultural relic, an actual monitoring mode is to acquire and detect whether the difference between material spectrum information of a preset detection position on the monitored cultural relic and material spectrum information of a material comparison label stored and recorded in advance is changed, the material comparison label plays a main role of serving as invisible comparison basic data, and meanwhile, the material spectrum difference is made to be obvious so as to be helpful for reducing monitoring judgment errors, and as the material comparison label does not exist in a monitored cultural relic site, but only serves as a comparison basic data form to participate in a monitoring judgment processing process, so that other people are difficult to acquire the actual situation of the difference value of the material spectrum information of the preset detection position in comparison with the material spectrum information of the material comparison label stored and recorded in monitoring, the calculation processing flow of the monitoring process used by the cultural relic protection monitoring method is greatly enhanced, and the monitoring influence and interference are not easy to be broken by a third party, and the information security of the cultural relic protection method is facilitated to be enhanced.
In this embodiment, as a preferred embodiment, a plurality of material areas may be disposed on the surface of the prefabricated material comparison label, and each material area may be disposed with a different kind of material. In this way, when judging whether the measured cultural relics are abnormal, the material spectrum information of the preset detection positions on the measured cultural relics which are collected by monitoring are respectively compared with the material spectrum information of each material region in the stored and recorded material comparison label, and if and only if the difference of the material spectrum information of the preset detection positions relative to the material spectrum information of each material region in the stored and recorded material comparison label is kept unchanged, the measured cultural relics are judged not to be abnormal; and if the difference between the material spectrum information of the preset detection position on the collected measured cultural relics and the material spectrum information of any material area in the material comparison label corresponding to the stored record is monitored to change, judging that the measured cultural relics are abnormal.
According to the monitoring scheme, the plurality of material areas are arranged on the surface of the material comparison label, and different types of materials are arranged in each material area, so that on one hand, when the material spectrum information of each material area in the material comparison label stored and recorded is involved in the monitoring and judging of the measured cultural relics with different materials, the different material spectrum information differences can be reflected more easily, the situation that the difference value of the material spectrum information before the material spectrum information of the surface material of some cultural relics possibly is smaller than that of the material spectrum information before the single material of the material comparison label is avoided, the difference change amount detection error is easy to generate, and even the condition that the difference change amount detection is difficult to accurately detect is avoided, and the method is widely applicable to the protection and monitoring of various cultural relics; on the other hand, as the material spectrum information of the material comparison label of the storage record becomes more diversified along with the material spectrum information, the material spectrum information of the preset detection position is correspondingly more diversified relative to the material spectrum information difference data of each material area in the material comparison label of the storage record, so that the confidentiality of the calculation processing flow of the monitoring process is further enhanced, and the detection process is less prone to being broken by a malicious third party.
In this embodiment, as another preferable scheme, a plurality of preset detection positions of the measured cultural relics may be designed; in this way, when judging whether the measured cultural relics are abnormal, the material spectrum information of each preset detection position on the measured cultural relics which are collected by monitoring is respectively compared with the material spectrum information of the material comparison label which is stored and recorded, and if and only if the difference of the material spectrum information of each preset detection position relative to the material spectrum information of the material comparison label which is stored and recorded is kept unchanged, the measured cultural relics are judged not to be abnormal; and if the difference of the material spectrum information of any one preset detection position on the collected measured cultural relics relative to the material spectrum information of the stored and recorded material comparison label is changed, judging that the measured cultural relics are abnormal.
According to the monitoring scheme, the material spectrum information of a plurality of preset detection positions on the measured cultural relics is monitored to be respectively compared with the material spectrum information of the material comparison label recorded by storage, so that on one hand, the identification amount of the comparison information is increased, the monitoring sensitivity is improved, on the other hand, if the measured cultural relics are subjected to translation, rotation, local damage displacement and the like, the material spectrum information of one or more preset detection positions is possibly changed, and accordingly the material spectrum information difference value is changed, and therefore the monitoring mode is also more beneficial to accurately judging whether the measured cultural relics are subjected to abnormal conditions such as rotary displacement or local damage and the like.
In this embodiment, as still another preferable scheme, while a plurality of preset detection positions of the measured cultural relics are designed, a plurality of prefabricated material comparison labels are also designed, corresponding material spectrum information is stored and recorded for each material comparison label, and each preset detection position of the measured cultural relics is designed to correspond to one material comparison label; in this way, when judging whether the measured cultural relics are abnormal, judging whether the difference of the material spectrum information of the preset detection position on the monitored and collected measured cultural relics relative to the material spectrum information of the corresponding material comparison label is kept unchanged; if and only if the difference of the material spectrum information of each preset detection position on the monitored and collected measured cultural relics relative to the material spectrum information of a corresponding material comparison label is kept unchanged, judging that the measured cultural relics are not abnormal; and if the difference of the material spectrum information of any one preset detection position on the collected measured cultural relics relative to the material spectrum information of the corresponding material comparison label is monitored to change, judging that the measured cultural relics are abnormal.
According to the monitoring scheme, the identification amount of the contrast information is increased, the monitoring sensitivity is improved, whether the detected cultural relics are subjected to abnormal conditions such as rotary displacement or local damage or not is more facilitated to be accurately judged, meanwhile, different preset detection positions can correspond to different material contrast labels, so that the difference data of the material spectrum information are more diversified, the protection monitoring method is more widely applicable to protection monitoring of various cultural relics, the predictability of the calculation processing flow of the monitoring process is further reduced, confidentiality is further enhanced, and the method is less prone to being broken by a third party maliciously.
