Problems solved by technology

This is because: 1. The collection of precious murals generally does not allow damage sampling
2. The sampling points cannot fully represent the overall situation of the murals in the collection
3. The samples are completely separated from the murals as a whole, so any analysis, detection, and evaluation of the murals in the collection cannot represent the overall situation of the murals

Embodiment 1

[0054] 1. For a mural in the collection of Inner Mongolia with an area of ​​about 3 square meters as the implementation object, it is divided into 24 areas according to the cutting line when it was removed, and the area of ​​each area is about 0.125 square meters, which are numbered sequentially. NMBH1-NMBH24.

[0055] Use a digital camera to take digital photos of the murals in each area, and select a total of 421 sample points in blue, green, black, orange-red, pink, red, white, gray, yellow, and brown for each area to mark , where the measurement points in one area (NMBH20) are marked as image 3 shown.

[0056] 2. Use a standard white board to calibrate the colorimeter and measure the sample points. Measure each sample point 3 times, calculate the average value, and establish a tolerance ball model, such as selecting blue, green, red, white, and yellow The samples are evaluated, and the standard colors are 19-4220TC, 19-0309TC, 19-1217TC, 17-0207TC, 17-1410TC in the pant...

Abstract

The invention discloses a non-destructive analysis method for surface pigment characteristics of a wall painting in a museum, in which a non-destructive testing analysis technology is adopted. The method as a quantifiable, workable, comparable and non-destructive evaluation method comprises the steps of evaluation analysis (quantitative analysis) on colors by establishing a tolerance sphere model, quality statistical analysis (quantitative analysis) on the pigment in a unit surface area of a wall paining, surface microscopic characteristic analysis (qualitative analysis) and pigment thickness analysis (quantitative analysis). By virtue of the non-destructive analysis method, a scientific conclusion on the preservation state of the wall painting is ensured, and a scientific evidence is provided for the technological protection and restoration of the wall paining by dividing zones on the painting wall in the museum and selecting a plurality of measurement points with comprehensive consideration of various factors. Moreover, abundant scientific detection data resources are provided for wall painting pigment database development and long-term preservation, protection, restoration, exhibition and management of the wall painting through statistics and analysis on a large amount of measurement data.

Description

technical field [0001] The invention belongs to the technical field of analysis, research and protection of murals in collections, and in particular relates to a non-destructive analysis method for surface pigment characteristics of murals in collections. [0002] It involves the acquisition and comparative analysis of the characteristic indicators of the surface pigments of the murals in the collection. Using non-destructive testing and analysis technology, a systematic evaluation method for the surface pigments of the murals in the collection is established, and a scientific conclusion is given on the preservation status of the murals, which provides a scientific basis for the scientific protection and restoration of murals. The large amount of data established provides technical parameters for the preservation, utilization and display of murals. The "non-destructive analysis method for surface pigment characteristics of murals in collections" of the present invention can pr...
