Problems solved by technology
At present, in the field of digital protection of cultural relics and artworks, the existing color cards are mostly international standard color cards. Most of these color cards are made by using matte paint to simulate the spectral characteristics of typical objects in nature. For creative materials and color cards The digital protection of cultural relics and artworks with similar material properties can play a good role in correcting color accuracy, but for painted cultural relics (such as Dunhuang painted cultural relics) mainly made of high-saturation mineral pigments, due to the material characteristics As a result, the commonly used standard color cards cannot control the color of such painted cultural relics very well.
Regarding the above problems, neither academia nor industry has yet proposed a method to accurately control the color of cultural relics in the process of digital protection of painted cultural relics made of high-saturation mineral pigments from the perspective of making color cards

Embodiment Construction
[0032] The technical solution of the present invention can be implemented by those skilled in the art using the raw materials, digital collection and reproduction equipment, color measurement equipment and supporting computer software technology produced by Dunhuang colored painted cultural relics. With reference to the drawings, a detailed description of the embodiments of the present invention is provided as follows.
[0033] Such as figure 1 As shown, the embodiment provides a method for making color correction color cards for Dunhuang painted cultural relics, which can solve the problem of color distortion in the digital protection process of Dunhuang painted cultural relics, and greatly improve the accuracy and color control of Dunhuang painted cultural relics. Control efficiency. The embodiment uses a Canon EOS 600D and a Canon EOS 6D digital camera as the acquisition device, an EIZO CG301W liquid crystal display with a hood as the reproduction device, and uses the Profilem...

The invention discloses a manufacturing method of a color correction color card for a painted cultural relic. The manufacturing method comprises the following steps: researching and studying painting color categories, a painting manufacturing process and an applying skill to construct a painting simulation sample set by taking a framed white cardboard as a base, oxhide gelatin as a binder and a paint as a dispersion phase; measuring spectral and chromatic information of the painting simulation sample set to establish a paint color database; performing color control evaluation between single-color simulation samples of different granularities aiming at the simulation samples of different granularities in the database to establish an initial painting color card; guiding color control testing of a digital camera and a display with the preliminarily determined color card, and supplementing and perfecting the color card through subjective and objective comprehensive evaluation to determine a final color card; typesetting, numbering and naming the finally determined color card to form a painting color card entity. The color card manufactured by the method has better color control capacity to acquisition and representation of painted artworks.
Description
[0001] technical field [0002] The invention belongs to the technical field of digital protection of cultural relics and artworks, and in particular relates to a method for making a color correction color card for painted cultural relics, in particular a method for making a color correction color card for painted cultural relics made of high-saturation mineral pigments. [0003] Background technique [0004] The digital protection methods and theories of cultural heritage are one of the mainstream technologies in the field of cultural relics protection at home and abroad. This technology digitally collects the original information of current cultural relics and artworks, and then establishes a corresponding artwork database for digital preservation and three-dimensional immersive display. Compared with the traditional artificial "damage" restoration method of protection of cultural relics and artworks, this digital protection technology for cultural relics minimizes the da...
