Embodiment Construction
[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0038] The invention provides a method for monitoring color decay of color paintings of ancient buildings. The color paintings are irradiated by two symmetrical D65 standard light sources, and the color of the color paintings is collected by a two-dimensional color luminance meter under the condition that the illumination of the color paintings is consistent. information, by calculating the color difference to evaluate the degree of color decay of the color painting.
[0039] like figure 1 As shown, a method for monitoring color decay of an ancient architectural color painting of the present invention comprises the following steps:
[0040] (1) When the sky is completely dark, u...

The invention discloses a method for monitoring the color decay of colored paintings of ancient buildings. When the sky is completely dark, two D65 standard light sources are used to irradiate the colored paintings, so as to ensure that the picture is evenly and softly lighted and has no strongly reflected light spots during measurement; The position and posture of the light source arrangement are repositioned to ensure that the illumination distribution on the surface of the color painting is the same as that of the last monitoring; the chromaticity of the color painting is detected by a two-dimensional color luminance meter, and the color coordinate value and lightness of the color painting are obtained value; according to the color coordinates and lightness value of the color painting, use the CIE DE2000 formula to calculate the color difference, and evaluate the degree of color decay of the color painting. The monitoring period is at least one quarter. The invention fills up the gap in the monitoring part of colored paintings in the field of ancient building protection, and has high environmental adaptability, good flexibility, quickness, convenience and high precision. The calculated color difference value reflects the color decay of the color painting, so as to scientifically and effectively evaluate the health status of the color painting, and provide data support for the protection of the color painting.
Description
technical field [0001] The invention relates to the field of protection and detection of ancient buildings, in particular to a color decay monitoring method for color paintings of ancient buildings. Background technique [0002] As a special part of cultural relics and buildings, colored paintings are not only beautiful and colorful, but also reflect the information of a specific historical era, and have high cultural and artistic value. However, colored paintings are one of the most sensitive types of cultural relics to changes in the natural environment, and are extremely vulnerable to erosion and damage. In order to strengthen the protection of the color paintings of ancient buildings, it is necessary to monitor the current status of them. At present, domestic and foreign research on the protection of color paintings in ancient buildings focuses on the degradation mechanism, maintenance methods, and restoration methods. [0003] Color is the most intuitive form of ancie...
