Abstract

The invention provides an article fingerprint extraction method and device and an article identity authentication method and device, and the article fingerprint extraction method comprises the steps: determining a fingerprint region on the surface of an article, and determining the guidance information of the fingerprint region; performing feature extraction on the image of the fingerprint area to obtain a target fingerprint; sending the target fingerprint to a database for storage for fingerprint verification, wherein the target fingerprint comprises a plurality of fingerprint vectors, each fingerprint vector comprises description information and feature information, and the feature information comprises a feature center coordinate, a neighborhood diameter and a feature direction. The fingerprint of the article is extracted through the fingerprint area on the surface of the article to determine the identity of the article, an anti-counterfeiting mark does not need to be additionally added, and distribution of anti-counterfeiting mark numbers and manufacturing of the anti-counterfeiting mark can be omitted. In addition, the fingerprint vector comprises a description vector, a feature center coordinate, a neighborhood diameter and a feature direction, the features of the fingerprint area can be accurately described, and the difficulty of counterfeiting the identity information of the article can be improved.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method and device for extracting fingerprints of articles and identifying the identity of articles. Background technique [0002] In order to avoid counterfeiting of items, it is necessary to identify the items, such as some commercially available high-grade ceramics, handicrafts and ancient relics. The anti-counterfeiting methods of current article labels or packaging include such as barcodes, fluorescent marks, holographic marks and watermarks, etc., which are all industrialized printing production. [0003] There is a problem that the identification information of the item is out of touch with the item itself in the current method for identifying the item's identity information, such as the above-mentioned barcode, fluorescent mark, holographic mark and water mark. These have brought great difficulties to market supervision, consumer identification and product tra...
