Problems solved by technology

Although the evaluation of Tibetan exhibition materials has been proposed for some time, there are many difficulties in the evaluation of Tibetan exhibition materials, and a fast and effective system has not been formed so far
The main difficulty is that the Oddy method takes a long time to test the material, and the cycle is 28 days. After the test piece is obtained, the material is mainly graded through manual visual observation. The classification depends on manual visual observation, which has certain subjectivity and error. larger

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] see figure 1 , the evaluation method of the present invention is as follows:

[0039] 1) Utilize the nano film test piece method to obtain the copper or silver test piece for detecting Tibetan exhibition materials

[0040]In 1973, Mr. Oddy of the British Museum proposed a detection method called "Oddy method" for Tibetan exhibition materials. This method uses lead sheets, copper sheets, and silver sheets as probes for detecting corrosive gases. During the experiment, put a piece of metal sheet and sample material in the experiment bottle, and put 1mL pure water (high relative humidity) at the same time. The test bottle is completely sealed, heated to 60°C, and kept warm for 28 days. Each experiment was repeated twice. Make a blank sample for each test, and then visually evaluate the test results. The material is acceptable if the sample material d...

Abstract

The invention relates to a method for quickly evaluating an exhibition material based on image processing, which comprises the following steps: firstly adopting a nano film test piece method to test the material, next using a designed image acquisition device to acquire images of the test piece, finally applying an image processing method to divide the acquired images of the test piece, and using the obtained division result to calculate the corroded area ratio of the test piece so as to grade the material, wherein the result is basically consistent with manual visual estimation and does not rely on human subjectivity. The method adopts the technology of material science, image processing, preservation of cultural relics and the like, effectively applies the image processing in the field of the preservation of cultural relics, and acquires better effect than other methods.

Description

technical field [0001] The invention relates to a rapid evaluation method of Tibetan exhibition materials, in particular to a rapid evaluation method of Tibetan exhibition materials based on image processing. Background technique [0002] The evaluation of collection and exhibition materials is to test and grade the materials often used by museums or art galleries in collection or display, so as to determine the applicability of materials. Due to its huge potential application in cultural relics protection and collection, it has been paid more and more attention. Although the evaluation of Tibetan exhibition materials has been proposed for some time, there are many difficulties in the evaluation of Tibetan exhibition materials, and a fast and effective system has not been formed so far. The main difficulty is that the Oddy method takes a long time to test the material, and the cycle is 28 days. After the test piece is obtained, the material is mainly graded through manual v...
