Problems solved by technology
However, the use of these information technologies mostly focuses on the research and analysis of mural structure and image texture, and the extracted features cannot completely and accurately represent the attributes of mural disease itself.
[0004] There are various diseases of murals. Scientific monitoring and analysis of murals is an important basis for the protection and restoration of ancient murals. At present, there is no comprehensive and effective monitoring method

Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0032] see figure 1 As shown, the embodiment of the present invention provides a mural monitoring method based on three-dimensional hyperspectral imaging, which includes:
[0033] Execute step A at regular intervals to generate multiple 3D models of murals at different times, where step A includes:
[0034] A1: Obtain the digital image of the mural, and generate the basic model of the mural based on the digital image;
[0035] A2: Obtain the spectral image and infrared image of the mural, and attach the spectral information corresponding to each pixel in the spectral image and the infrared information corresponding to each pixel in the infrared image to the basic model of the mural after calculation and processing to generate a three-dimensional mural Model;
[0036] The three-dimensional models of murals generated at different times were c...

The invention discloses a three-dimensional hyperspectral imaging-based wall painting monitoring method, and relates to the technical field of wall painting monitoring. The method comprises the stepsof executing the step A per certain time, and generating a plurality of wall painting three-dimensional models at different times, wherein the step A comprises the steps of A1, acquiring a digital image of a wall painting, and generating a wall painting basis model according to the digital image; and A2, acquiring a spectrum image and an infrared image of the wall painting, attaching spectrum information corresponding to each pixel point in the spectrum image and infrared information corresponding to each pixel point in the infrared image to the wall painting basis model to generate the wall painting three-dimensional model after operation and processing; and performing comparison and analysis on the wall painting three-dimensional models generated at different times to obtain change of apigment layer, phenotype and an internal structure of the wall painting. By the method, comprehensive monitoring of the pigment layer change, the phenotype change and the internal structure change ofthe wall painting can be achieved.
Description
technical field [0001] The invention relates to the technical field of mural monitoring, in particular to a mural monitoring method based on three-dimensional hyperspectral imaging. Background technique [0002] Murals are the product of the combination of history and art. They reflect the economic and cultural development and ideology of various historical periods from different aspects. The information helps archaeologists to understand the development track and state of history. Today, as the protection of cultural relics is becoming more and more important, the factors of man-made destruction of murals have been basically eliminated, but the damage of natural factors to high murals is becoming more and more obvious, and there are signs of acceleration. The damage forms include damp running water, mold, hollowing, cracks, peeling, Peeling, fading or even collapsing. [0003] With the development of information technology, technologies such as digital photography and imag...
