Problems solved by technology

However, these methods are not specific to cultural heritage conservation, and there is not even a method specific to the analysis and visualization of mural disease at present.
[0005] Although many investigations and research works have been carried out and more and more census and monitoring data on murals are stored in databases, the analysis, visualization, and understanding of diseases are very challenging due to the following reasons, first , the complexity of the disease partly depends on the complexity of the structure of the mural itself; second, due to the diversity of data acquisition methods and descriptions, the data is heterogeneous, multi-dimensional, and multi-attribute; third, the degradation of the mural disease The mechanism is very complicated, because most of the diseases are the result of a combination of factors; fourth, most of the murals have experienced a long history before they were discovered, so the time that has been monitored and recorded is relatively short Therefore, the information and data used to study the disease are limited, especially the information on the formation process and mechanism is very little; fifth, the disease has different characteristics, and is often divided into stable diseases and active diseases

Embodiment 1

[0035] Embodiment 1, the symbiosis pattern of disease:

[0036] According to the steps of the method of the present invention, the concentric ring diagram reflecting the disease type information of the grotto murals is obtained, and the information of two types of diseases, cracks and hollows, which exist in the grotto murals are selectively displayed therefrom, such as image 3 As shown, it can be clearly concluded that most of the caves have cracks and hollows, and the dark gray and light gray histograms represent cracks and hollows respectively, which occupy most of the area of ​​the ring. And hollowing and cracking appear almost at the same time, so we can think that cracking and hollowing are symbiotic, that is, when one disease exists, another disease will exist at the same time. Experts in the field were consulted on the basis of the observations, who affirmed the result and explained the symbiosis: since both diseases are related to the stability of the cave building s...

Embodiment 2

[0037] Embodiment 2, the relevant disease pattern of dynasty

[0038] According to the steps of the method of the invention, concentric ring diagrams reflecting the information of cave mural disease types are obtained, and caves built in different periods are selectively displayed therefrom. As shown in Figure 4(a), a total of 8 caves were built during the Northern Liang Dynasty, 7 of which were built on the third floor, and 1 was built on the second floor, and the distribution of disease colors in the figure can be It can be seen that most of the mural diseases in the caves of this dynasty are cracks, hollows, peeling, and falling off. As shown in Figure 4(b), a total of 90 caves were built in the Sui Dynasty, most of the caves were located on the second and third floors, and only 5 caves were on the ground floor. There are 4 out of the 5 caves in the bottom layer with chorizo ​​disease (80%); 9 out of 64 caves in the middle layer have chorizo ​​disease (14%); in the 21 cave...

Embodiment 3

[0039] Embodiment 3, spatial disease clustering mode

[0040] According to the steps of the method of the present invention, a concentric ring diagram reflecting the type information of cave mural diseases is obtained. We select each type of disease to be displayed separately in order to test their distribution patterns, and two of the eight types of diseases show clustering. As shown in Figure 5(a) the dark gray histogram represents that most of the sulfhydric acid is distributed in the outermost layer, and as shown in Figure 5(b) the light gray histogram represents that most of the herpes are distributed in the outermost layer. We guess that these two diseases seem to be related to the ground. According to this phenomenon, experts in the field were consulted. They affirmed this result and gave an explanation, because these two diseases are caused by soluble salt and water, and the closer to the ground cave The more moisture, and therefore the higher the potential to trigger ...

Abstract

The invention discloses a method for determining a disease mode of ancient stone cave temple wall paintings based on visual analysis. The method includes that a foundation database of stone cave temple caverns is established, the database contains location information and construction dynasty of the caverns, disease information and general survey time, and all disease information is high-dimensional feature vectors. The location information of a certain stone cave temple is read from the foundation database of the stone cave temple caverns. And then by the aid of a multilayered circular ring, the disease information of each layer of caverns of the stone cave temple under a same general survey time is at intervals distributed in the circular ring covered by a sector area in a same rotation direction with a bar graph form for simulating the effect of a heritage site panorama so as to discover the disease mode of the whole stone cave temple. By the aid of the method, work efficiency of related personnel in the field of culture heritage can be improved, and a solid foundation is established for cultural heritage protection.

Description

technical field [0001] The invention relates to a visual analysis and interactive technical means to realize the disease analysis system of ancient grotto temple murals, in particular to a method for determining the disease pattern of ancient grotto temple murals based on visual analysis. Background technique [0002] Cultural heritage is the precious wealth left to people by history. In today's globalization, the protection of traditional culture has gradually become a major focus of attention of governments and people around the world. As a world cultural heritage, the murals of cave temples, such as the Dunhuang Mogao Grottoes in my country, are famous for their exquisite murals in the caves. However, these precious murals are suffering from man-made damage and degradation caused by the natural environment. They may be the result of physical, chemical, biological and other factors, including natural aging, environmental degradation and human activities. Therefore, the mu...
