Problems solved by technology

Traditionally, the extraction and analysis of mural disease information mainly use the transparent grid method and CAD method. These two methods not only involve a lot of manual work, but also have the disadvantages of strong subjectivity, low efficiency, and time-consuming and labor-intensive.

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0042] Hyperspectral image information has a very broad spectrum coverage, including visible light, near-infrared, mid-infrared and thermal infrared bands. In these spectral ranges, it accurately records the spectral reflectance of the target. Due to the continuity of the spectrum, it can Provide a continuous spectrum curve to realize the simultaneous recording of target spectral information and spatial information. Hyperspectral imaging technology has high spectral resolution and small spectral intervals, so adjacent spectra contain a large amount of overlapping information, which provides the possibility for continuous imaging of images. Due to the differences in the material composition of different ground objects, they have different spectral reflectance characteristic cu...

Abstract

The invention discloses a wall painting information extraction method based on hyperspectral imaging. The method comprises the following steps of: 1, acquiring original hyperspectral image information of a wall painting in a preset region; and 2, extracting draft information of the wall painting, pigment information of the wall painting and disease information of the wall painting according to the original hyperspectral image information. According to the wall painting information extraction method based on the hyperspectral imaging, the wall painting information is extracted and analyzed according to the advantages of a hyperspectral technology, so that the shortcomings of large working amount, large error, multiple manmade factors and the like of the conventional wall painting information investigation and analysis method are overcome; the wall painting information extraction method has the characteristics of quickness and effectiveness; the shortcoming of insufficient spectral information in dispersion wave band in a multi-spectrum technology is overcome; and the wall painting information extraction method has the advantages of spectrum continuity and rich data and is favorable for quick, effective and scientific analysis of wall painting information, so that instruction and basis are supplied to deep research and protective repair on the wall painting information.

Description

technical field [0001] The invention relates to a mural information extraction method, in particular to a mural information extraction method based on hyperspectral imaging. Background technique [0002] Murals are the product of the combination of history and art. It reflects the economic and cultural development and ideology of various historical periods from different aspects. Its information helps archaeologists understand the development track and state of history and analyze early art studies It is helpful to guide the mural protection workers to formulate reasonable protection and restoration plans. [0003] At present, the extraction of mural manuscript information only uses the visible light band, which has the limitation of incomplete information. With the expansion of the spectral range, the visualization range of mural information has been increased, but the extraction of mural manuscript information still uses visual recognition. method with low efficiency. ...
