Locating membrane

Abstract

The embodiment of the invention provides a locating membrane. The locating membrane is applied to an evidence taking scene of an evidence taking object; the locating membrane covers the surface of the evidence taking object during evidence taking, the locating membrane is a transparent membrane, and the surface of the transparent membrane is provided with at least one locating area and identification information of the locating area; the locating membrane can be used for realizing accurate location and accurate recording of feature points and characteristic regions of the evidence taking object, solving the problem of inaccurate manual annotation of the feature points and the characteristic regions on a copied part or a mini-printed part, and also solving the problem of data error caused by manual recording, comparison of the characteristic region and a microimage and the like; and besides, the locating membrane is only required to be cover the surface of the evidence taking object to acquire an image in the whole evidence taking process, the micro evidence taking process is greatly simplified, the efficiency is improved, and the locating membrane can protect the evidence taking object when covering the evidence taking object.

Description

technical field [0001] The invention relates to the technical field of artwork anti-counterfeiting identification equipment, in particular to a positioning film. Background technique [0002] At present, the art market is booming, and more and more investors are beginning to pay attention to the field of art investment. However, as original works come out continuously, more and more imitations and counterfeit products are also produced. Counterfeiting and counterfeiting involve various categories of art collections, such as calligraphy and painting, ceramics, jade, bronze and so on. Therefore, the anti-counterfeiting identification of artworks is particularly important. [0003] The commonly used art anti-counterfeiting appraisal method is to compare and verify the microstructure of the artwork to be appraised and the filed artwork. Mistakes in the filing process will not only make the entire identification process meaningless and even have negative effects. [0004] In t...

[0005] However, in this process, the method of manually marking and determining the feature points on the image of the work that has been reduced several times is very imprecise, and the actual area of ​​the picture circled by a circle with a diameter of about 4mm may be very large on the evidence. Moreover, the method of manually recording the position of feature points is also very error-prone and low in efficiency.
