Embodiment Construction

[0033] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] The main solution of the embodiment of the present invention is:

[0035] Obtain the logo image on the paper to be collected;

[0036] judging whether the logo image completely falls within the first preset image frame;

[0037] When the identification image completely falls within the first preset image frame, the texture image of the paper to be captured is collected.

[0038] Because in the prior art, the texture image of the paper can only be collected by the user subjectively judging the collection area and manually clicking to take pictures, the accuracy of the collection result is low.

[0039] The present invention provides a solution, so that the terminal can automatically collect the texture image of the paper when the logo image completely falls into the preset image frame, so that the collection o...

Abstract

The invention discloses a paper texture acquisition method. The paper is provided with an identifier, and the paper texture acquisition method comprises the following steps: acquiring an identifier image on the paper to be acquired; judging whether the identification image exceeds a first preset image frame or not; and when the identification image exceeds the first preset image frame, acquiring atexture image of the to-be-acquired paper. The invention further discloses a paper texture acquisition device and a storage medium. According to the invention, the object distance can be controlled by identifying the size of the image, so that the pixel points of the image corresponding to the paper in the unit area in the acquired paper texture image are enough to analyze clear texture features,and the texture image acquisition of the paper is more accurate.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a method, a device and a storage medium for collecting paper texture. Background technique [0002] The natural texture of paper can be used for anti-counterfeiting due to its irreproducibility. However, since the natural texture of paper is very complex, the texture information needs to be obtained through analysis. Therefore, the texture image is generally collected through the terminal, and then the texture image is analyzed to obtain the texture feature information. [0003] When collecting the texture image of paper, the object distance can only be controlled by the user's subjective judgment, and the accuracy of the collection result is low. [0004] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0005] T...
