Description

Technical Field

[0001] The present invention relates to the technical field of calligraphy and painting evaluation, and in particular to a calligraphy and painting evaluation method. Background Art

[0002] In recent years, calligraphy and painting collections have become a new form of financial management, and their value is a topic of great concern to collectors and the public. However, it is difficult to have an authoritative organization or a generally accepted method to judge or evaluate the value and price of calligraphy and painting. A major characteristic that distinguishes calligraphy and painting from other commodities is their heterogeneity. That is, each piece of calligraphy and painting is unique, and there is no direct comparability between different works of calligraphy and painting, and it is impossible to calculate the average price of multiple pieces of calligraphy and painting through arithmetic methods.

[0003] After checking the publication number: CN115099879A, a method and device for evaluating the value of calligraphy and painting are disclosed. This technology discloses "a method and device for evaluating the value of calligraphy and painting, the method comprising: obtaining sample data to be trained, the sample data to be trained being historical transaction data of calligraphy and painting; extracting characteristic variables of the sample data to be trained, and cleaning the characteristic variables; using the characteristic variables to train a characteristic price model, and evaluating the value of calligraphy and painting based on the characteristic price model". The technical solution has the following technical effects: "using a large amount of real calligraphy and painting transaction data as sample data to train the characteristic price model, and testing and optimizing the model. It can be seen from the experimental data that the characteristic price model obtained by the present invention is used to evaluate the price of calligraphy and painting, and a relatively accurate and objective evaluation result can be obtained".

[0004] Existing calligraphy and painting valuation methods primarily rely on the subjective judgment of the evaluator, which can lead to inconsistent results due to differences in personal experience, preferences, or cognition, making it difficult to guarantee objectivity and accuracy. Furthermore, market transactions may contain unusually high or low prices. Relying solely on a single case as a reference can easily distort the valuation results and fail to truly reflect market conditions. Furthermore, due to the lack of systematic quantitative standards, valuation results often lack scientific basis, making it difficult to meet the demand for reliable value references in fields such as collection, trading, and insurance. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a calligraphy and painting evaluation method, which quantifies the differences between the evaluation subject and the sample in terms of popularity, artistic level, size, mounting and integrity through a coefficient formula, making the correction value more accurate; and eliminates the randomness of a single sample by averaging the correction values ​​of multiple samples.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A calligraphy and painting evaluation method comprises the following steps:

[0007] S1, confirm the authorship of calligraphy and painting, determine the creation time of the work, and measure the size of calligraphy and painting;

[0008] S2, authenticates calligraphy and painting through style analysis, technical testing, inscriptions and seals;

[0009] S3, select multiple market transaction cases of the same author of the evaluation target as comparison samples;

[0010] S4, correct the samples separately, and the correction formula is: Correction value = sample value × well-known coefficient × art coefficient × size coefficient × mounting coefficient × intact coefficient, where the sample value represents the actual transaction price of the same artist's calligraphy and painting works in the market;

[0011] S5, calculate the fame coefficient, artistic coefficient, size coefficient, mounting coefficient, and intact coefficient. The corresponding coefficient is the ratio of the corresponding parameter value of the target to the corresponding parameter value of the sample;

[0012] S6, averaging the multiple correction values ​​to obtain an evaluation value.

[0013] Preferably, the style analysis in S2 is to compare with other works of the author, analyze the characteristics of brushwork, composition, and color, and judge whether it conforms to the author's artistic style; the technical inspection is to use professional equipment to detect materials, pigments, and ink marks, and confirm the age and authenticity of the work; the inscription and seal identification is to compare with the author's known inscriptions and seals to confirm their authenticity.

[0014] Preferably, the parameters corresponding to the well-known coefficient in S4 include: well-known works, famous works, well-known works, fine works, and general works, and the corresponding parameter values ​​are 5, 4, 3, 2, and 1 respectively.

[0015] Preferably, the parameters corresponding to the art coefficient in S4 include: customized works, creative works, ordinary works, social works, and essay works, and the corresponding parameter values ​​are 5, 4, 3, 2, and 1 respectively.

[0016] Preferably, the parameter corresponding to the size coefficient in S4 is the size area of ​​the work.

[0017] Preferably, the parameters corresponding to the mounting coefficient in S4 include: original mounting, old mounting, and new mounting, and the corresponding parameter values ​​are 3, 2, and 1, respectively.

[0018] Preferably, the parameters corresponding to the intact coefficient in S4 include: intact works, basically intact works, generally damaged works, and seriously damaged works, and the corresponding parameter values ​​are 4, 3, 2, and 1, respectively.

[0019] Preferably, the coefficient formula in S5 is:

[0020]

[0021] The parameter values ​​in the formula are the corresponding parameter values ​​of the samples in terms of popularity, artistic level, size, mounting, and completeness.

[0022] Preferably, the evaluation value formula in S6 is:

[0023]

[0024] Where ∑correction value represents the sum of the correction values ​​of all samples, and the number of samples represents the total number of samples.

[0025] The present invention provides a calligraphy and painting evaluation method. Compared with the prior art, it has the following advantages:

[0026] 1. The coefficient formula quantifies the differences between the evaluation subject and the sample in terms of popularity, artistic level, size, mounting, and intactness, making the correction value more accurate. The coefficient formula is based on mathematical calculations, avoiding the arbitrariness of subjective judgment and making the evaluation results more scientific and objective. In addition, it is applicable to works of different authors, different eras, and different themes, and has strong versatility.

[0027] 2. By averaging the corrected values ​​of multiple samples, the impact of the randomness of a single market transaction case on the evaluation results can be avoided; using the average of multiple samples as the evaluation value can better reflect the overall market conditions, rather than just the performance of a single case.

[0028] 3. Style analysis involves comparing the work with other works by the author, analyzing the characteristics of the brushwork, composition, and color, and determining whether they conform to the author's artistic style. Technical testing involves using professional equipment to test materials, pigments, and ink marks to confirm the age and authenticity of the work. Inscription and seal authentication involves comparing the work with the author's known inscriptions and seals to confirm their authenticity. Through style analysis, technical testing, and inscription and seal authentication, the authenticity of the work can be verified from multiple dimensions, significantly improving the accuracy of the authentication results.

[0032] S1, confirm the authorship of calligraphy and painting, determine the creation time of the work, and measure the size of calligraphy and painting;

[0033] S2, authenticates calligraphy and painting through style analysis, technical testing, inscriptions and seals;

[0034] S3, select multiple market transaction cases of the same author of the evaluation target as comparison samples;

[0035] S4, correct the samples separately, and the correction formula is: Correction value = sample value × well-known coefficient × art coefficient × size coefficient × mounting coefficient × intact coefficient, where the sample value represents the actual transaction price of the same artist's calligraphy and painting works in the market;

[0038] In this implementation plan, by confirming the author's identity, creation time and size, basic data is provided for the evaluation to ensure the accuracy and scientific nature of the evaluation; secondly, by combining style analysis, technical testing and inscription and seal identification, the authenticity of the work is verified in multiple dimensions, significantly improving the accuracy and credibility of the identification results; then, market transaction cases of the same author are selected as comparison samples, and the quantitative correction formula fully considers the differences in the works' popularity, artistic level, size, mounting, preservation status, etc., making the evaluation results more scientific and objective; finally, by averaging multiple correction values, the randomness of a single sample is eliminated, making the evaluation results more representative and reliable. This method has clear steps and is easy to operate. It is applicable to calligraphy and painting works of various types and ages, and can provide a reliable market value reference for collection, trading, insurance, etc., with high practicality and versatility.

[0039] Specifically, the style analysis in S2 is to compare the author's other works, analyze the characteristics of brushwork, composition, and color, and determine whether they conform to the author's artistic style. Technical inspection is to use professional equipment to detect materials, pigments, and ink marks to confirm the age and authenticity of the work. Inscription and seal identification is to compare the author's known inscriptions and seals to confirm their authenticity.

[0040] In this embodiment, style analysis can be carried out by analyzing the brushstrokes, lines, strength, etc. of the work to determine whether it conforms to the author's writing habits, analyzing the layout, spatial relationship, theme expression, etc. of the work to determine whether it conforms to the author's composition characteristics, analyzing the color matching, tonal application, etc. of the work to determine whether it conforms to the author's color style; in technical inspection, microscopes, ultraviolet lamps and other equipment can be used to detect the material and aging degree of paper and silk, spectral analysis and other technologies can be used to detect the composition and age of pigments, and infrared scanning and other technologies can be used to detect the penetration and distribution of ink; in the inscription and seal identification, the author's known inscriptions can be compared to analyze whether the font, handwriting, content, etc. are consistent, and the author's known seals can be compared to analyze whether the seal text, ink color, seal shape, etc. are consistent; through style analysis, technical inspection and inscription and seal identification, the authenticity of the work can be verified in multiple dimensions, significantly improving the accuracy of the identification results.

[0041] Specifically, the parameters corresponding to the fame coefficient in S4 include: well-known works, famous works, well-known works, fine works, and general works, and their corresponding parameter values ​​are 5, 4, 3, 2, and 1 respectively.

[0042] In this embodiment, a well-known work (parameter value 5) indicates that the work is the most representative work of the author, with extremely high popularity and market recognition; a famous work (parameter value 4) indicates that the work is an important work of the author, with high popularity and market recognition; a well-known work (parameter value 3) indicates that the work is a well-known work of the author, with a certain degree of market recognition; a fine work (parameter value 2) indicates that the work is a fine work of the author, with a high artistic level but relatively low popularity; an ordinary work (parameter value 1) indicates that the work is an ordinary work of the author, with average artistic level and popularity; the popularity coefficient is used to quantify the popularity of the work, making the evaluation result more accurate and able to accurately reflect the impact of popularity on the value of the work. The higher the popularity, the higher the value.

[0043] Specifically, the parameters corresponding to the art coefficient in S4 include: customized works, creative works, ordinary works, social works, and casual works, and their corresponding parameter values ​​are 5, 4, 3, 2, and 1 respectively.

[0044] In this embodiment, customized works (parameter value 5) indicate that the works are carefully created by the author according to specific needs or themes, and have extremely high artistic level and uniqueness; creative works (parameter value 4) indicate that the works are completed by the author during the peak period or important stage of creation, and have high artistic level and innovation; ordinary works (parameter value 3) indicate that the works are daily creations of the author, with average artistic level, but still have certain artistic value; social works (parameter value 2) indicate that the works are completed by the author for social occasions or social occasions, with low artistic level, and are mostly perfunctory works; essay works (parameter value 1) indicate that the works are created casually by the author, with the lowest artistic level, and are mostly exercises or drafts; the artistic level of the works is quantified through the artistic coefficient, making the evaluation results more accurate and able to accurately reflect the impact of the artistic level on the value of the works. The higher the artistic level, the higher the value.

[0045] Specifically, the parameter corresponding to the size coefficient in S4 is the size area of ​​the work.

[0046] In this embodiment, the size of the work = length of the work × width of the work. The size coefficient is used to quantify the size difference between the evaluation target and the sample, making the correction value more accurate. The size coefficient can accurately reflect the impact of the size on the value of the work. Generally, the larger the size, the higher the value.

[0047] Specifically, the parameters corresponding to the mounting coefficient in S4 include: original mounting, old mounting, and new mounting, and the corresponding parameter values ​​are 3, 2, and 1, respectively.

[0048] In this embodiment, original mounting and original decoration (parameter value 3) indicates that the work maintains its original decoration state and has not been repaired or re-mounted, and has high historical and artistic value; old mounting and old decoration (parameter value 2) indicates that the work has been re-mounted in history, and the mounting materials and techniques are similar to the original mounting, and has certain historical value; new mounting and new decoration (parameter value 1) indicates that the work has been re-mounted in modern times, and the mounting materials and techniques are modern processes, and has lower historical value; through the mounting coefficient, the mounting quality of the work is quantified, making the evaluation result more accurate and able to accurately reflect the impact of the mounting quality on the value of the work. The better the mounting quality, the higher the value.

[0049] Specifically, the parameters corresponding to the intact coefficient in S4 include: intact works, basically intact works, generally damaged works, and severely damaged works, and their corresponding parameter values ​​are 4, 3, 2, and 1 respectively.

[0050] In this embodiment, an intact work (parameter value 4) indicates that the work is well preserved, without any damage, stains, insect bites, or other problems, and is completely framed; a basically intact work (parameter value 3) indicates that the work has slight damage, but does not affect the overall viewing and preservation, such as slight creases, local fading, etc.; a generally damaged work (parameter value 2) indicates that the work has moderate damage, which may affect the viewing and preservation, such as local damage, obvious stains, etc.; a seriously damaged work (parameter value 1) indicates that the work is severely damaged, affecting the overall viewing and preservation, such as large-scale damage, severe fading, etc. The intact coefficient is used to quantify the preservation condition of the work, making the evaluation result more accurate and accurately reflecting the impact of the preservation condition on the value of the work. The better the preservation condition, the higher the value.

[0051] Specifically, the coefficient formula in S5 is:

[0052]

[0053] The parameter values ​​in the formula are the corresponding parameter values ​​of the samples in terms of popularity, artistic level, size, mounting, and completeness.

[0054] In this embodiment, the differences between the evaluation subject and the sample in terms of popularity, artistic level, size, mounting, and intactness are quantified through a coefficient formula, making the correction value more accurate; the coefficient formula is based on mathematical calculations, avoiding the arbitrariness of subjective judgment and making the evaluation results more scientific and objective; and it is applicable to works of different authors, different eras, and different themes, and has strong versatility.

[0055] Specifically, the evaluation value formula in S6 is:

[0056]

[0057] Where ∑correction value represents the sum of the correction values ​​of all samples, and the number of samples represents the total number of samples.

[0058] In this embodiment, the average calculation is performed through the corrected values ​​of multiple samples, which can avoid the impact of the randomness of a single market transaction case (such as an abnormally high price or low price) on the evaluation result; using the average value of multiple samples as the evaluation value can better reflect the overall market conditions, rather than just the performance of a single case; and the average calculation is a statistical method that can reduce the interference of subjective judgment and make the evaluation results more scientific and objective. The method of calculating the average value is simple and intuitive, easy to understand and operate, and suitable for practical applications.
