Problems solved by technology

This technical solution mainly establishes a feature point database, and then analyzes the specificity of the feature point data and compares them. However, there are differences in the identification of feature points in different works, and the compatibility of the algorithm needs to be verified. An image with more than 3 million pixels is used as a record, that is, the multiple does not change, so it is impossible to compare under different multiples, and it cannot effectively guarantee the authority of the appraisal

Embodiment 1

[0033] The calligraphy and painting record identification device based on multi-level magnification includes a semi-closed housing 1 with an opening at the bottom, a main board (not shown in the figure) arranged in the housing, and a display screen 5 electrically connected to the data output end of the main board. , a data storage unit electrically connected to the data input end of the main board, a matching degree analysis module electrically connected to the data input end of the main board, a wireless communication module connected to the data output end of the main board, and several images electrically connected to the data input end of the main board Acquisition device, the image acquisition devices are N with the same or different magnifications at a fixed relative distance, N≥2, and M image acquisition devices with different magnifications, M≥2, N≥M. In this embodiment, the low-magnification camera 2, the medium-magnification camera 3, and the high-magnification camera...

Embodiment 2

[0044] In step 2), judge the spatial correspondence in one of the filing areas. In order to simplify the structure of the device and reduce the size of the screen, the identification device only judges the spatial parameters and will not display the corresponding images (if the screen is large enough, it can simultaneously display two registered pictures corresponding to different spatial relationships, and display images of corresponding multiples of the area in real time), for example, Figure 8 In the filing area A, when the distance between the high-magnification and medium-magnification cameras is constant, there are a pair of "△" and "○" corresponding to each other in the high-magnification area and the medium-magnification area, and when one of the features ("△" When the position of another feature ("○" or "△") is determined, the position of another feature ("○" or "△") must also be determined, so that when authenticating a work, even if the imitation imitates two differ...

Embodiment 3

[0048] Such as Figure 7 As shown, in the auxiliary identification algorithm, assuming a1 is the deviation vector between the real-time image and the record picture under the current multiple (30X), assuming b1 is the moving vector of the real-time image under the current multiple (30X), there is a deviation a1-b1, Assuming that a2 is the deviation vector between the real-time image and the filing picture under the condition of adjacent high magnification (600X), there is a deviation a1-b1-a2, and c is set as the minimum side length of the filing area under the condition of adjacent high magnification (600X), which is constant.

[0049] It is set that when |a1-b1-a2|≥c, that is, when the deviation is greater than the minimum side length of the filing area under high magnification conditions, it is judged as an original painting that is not registered.

Abstract

The invention provides a calligraphy and painting record authentication device based on multistage magnification times. The device comprises a housing, a main board, a display screen, a storage unit and image acquisition devices. The technical key points are that the number of the image acquisition devices, of which the relative distance is fixed and magnification times are same or different, is N, N>=2; and the number of the image acquisition devices, of which the magnification times are different, is M, M>=2, and N>=M. The calligraphy and painting record authentication device has the advantages of simple system, high record and authentication efficiency, reliable authentication result, low authentication cost, high anti-counterfeiting capability and easy popularization and the like.

Description

technical field [0001] The invention relates to the field of calligraphy and painting appraisal equipment, in particular to a calligraphy and painting record appraisal device based on multi-stage magnification. Background technique [0002] There are a large number of counterfeit goods in the calligraphy and painting industry, which makes the calligraphy and painting market chaotic and indistinguishable from real and fake, artists are infringed, and collectors suffer economic losses. For this reason, the state advocates the establishment of identity information for works of art such as calligraphy and painting. A large number of record identification methods and equipment have emerged in the calligraphy and painting industry. High, weak anti-counterfeiting ability, high cost. [0003] A calligraphy and painting magnified hundreds of times will reveal the internal microstructure, and the probability of the internal microstructure of different calligraphy and painting or diff...
